Errant reference in macOS 15.2 seems to confirm M4 MacBook Airs for 2025

The macOS 15.2 update that was released earlier today came with a handful of new features, plus something unexpected: an apparently accidental reference to the upcoming M4 MacBook Airs. MacRumors reports that the “Mac16,12” and “Mac16,13” model identifiers reference 13- and 15-inch models of the M4 Air and that both are coming in 2025.

That a MacBook Air refresh is planned for next year isn’t much of a surprise at this point—in reporting that pretty much nailed the details of the first M4 Macs, Bloomberg’s Mark Gurman has said that the Air, the Mac Studio, and the Mac Pro are all slated for updates throughout 2025.

But a reference in the current release of macOS could point to a launch sooner rather than later; the M4 Mac mini was referenced in a macOS update in mid-September around a month and a half before it was released. The M3 Airs came out in March this year, but Apple has been known to put out new Macs as early as January in recent years.

The M4 isn’t a gigantic update over the M3—we tested its performance in the M4 iMac, though a passively cooled MacBook Air version would likely be a bit slower at heavier workloads—but the fully enabled version does come with two extra CPU cores and some nice quality-of-life updates. Those updates include Thunderbolt 5 ports and support for a total of three displays (two external and the built-in screen), up from a total of two for the M1, M2, and M3 MacBook Airs.

We didn’t get M4 MacBook Airs in November, but Apple did “update” the M2 and M3 versions from 8GB to 16GB of RAM without increasing their prices. The RAM increase will be useful for all kinds of things, though it could be a harbinger of increased memory requirements for upcoming Apple Intelligence features.

Join us tomorrow for Ars Live: How Asahi Linux ports open software to Apple’s hardware

One of the key differences between Apple’s Macs and the iPhone and iPad is that the Mac can still boot and run non-Apple operating systems. This is a feature that Apple specifically built for the Mac, one of many features meant to ease the transition from Intel’s chips to Apple’s own silicon.

The problem, at least at first, was that alternate operating systems like Windows and Linux didn’t work natively with Apple’s hardware, not least because of missing drivers for basic things like USB ports, GPUs, and power management. Enter the Asahi Linux project, a community-driven effort to make open-source software run on Apple’s hardware.

In just a few years, the team has taken Linux on Apple Silicon from “basically bootable” to “plays native Windows games and sounds great doing it.” And the team’s ultimate goal is to contribute enough code upstream that you no longer need a Linux distribution just for Apple Silicon Macs.

On December 4 at 3: 30 pm Eastern (1: 30 pm Pacific), Ars Technica Senior Technology Reporter Andrew Cunningham will host a livestreamed YouTube conversation with Asahi Linux Project Lead Hector Martin and Graphics Lead Alyssa Rosenzweig that will cover the project’s genesis and its progress, as well as what the future holds.

Review: The fastest of the M4 MacBook Pros might be the least interesting one


Not a surprising generational update, but a lot of progress for just one year.

In some ways, my review of the new MacBook Pros will be a lot like my review of the new iMac. This is the third year and fourth generation of the Apple Silicon-era MacBook Pro design, and outwardly, few things have changed about the new M4, M4 Pro, and M4 Max laptops.

Here are the things that are different. Boosted RAM capacities, across the entire lineup but most crucially in the entry-level $1,599 M4 MacBook Pro, make the new laptops a shade cheaper and more versatile than they used to be. The new nano-texture display option, a $150 upgrade on all models, is a lovely matte-textured coating that completely eliminates reflections. There’s a third Thunderbolt port on the baseline M4 model (the M3 model had two), and it can drive up to three displays simultaneously (two external, plus the built-in screen). There’s a new webcam. It looks a little nicer and has a wide-angle lens that can show what’s on your desk instead of your face if you want it to. And there are new chips, which we’ll get to.

That is essentially the end of the list. If you are still using an Intel-era MacBook Pro, I’ll point you to our previous reviews, which mostly celebrate the improvements (more and different kids of ports, larger screens) while picking one or two nits (they are a bit larger and heavier than late-Intel MacBook Pros, and the display notch is an eyesore).

New chips: M4 and M4 Pro

That leaves us with the M4, M4 Pro, and M4 Max.

We’ve already talked a bunch about the M4 and M4 Pro in our reviews of the new iMac and the new Mac minis, but to recap, the M4 is a solid generational upgrade over the M3, thanks to its two extra efficiency cores on the CPU side. Comparatively, the M4 Pro is a much larger leap over the M3 Pro, mostly because the M3 Pro was such a mild update compared to the M2 Pro.

The M4’s single-core performance is between 14 and 21 percent faster than the M3s in our tests, and tests that use all the CPU cores are usually 20 or 30 percent faster. The GPU is occasionally as much as 33 percent faster than the M3 in our tests, though more often, the improvements are in the single or low double digits.

For the M4 Pro—bearing in mind that we tested the fully enabled version with 14 CPU cores and 20 GPU cores, and not the slightly cut down version sold in less expensive machines—single-core CPU performance is up by around 20-ish percent in our tests, in line with the regular M4’s performance advantage over the regular M3. The huge boost to CPU core count increases multicore performance by between 50 and 60 percent most of the time, a substantial boost that actually allows the M4 Pro to approach the CPU performance of the 2022 M1 Ultra. GPU performance is up by around 33 percent compared to M3 Pro, thanks to the additional GPU cores and memory bandwidth, but it’s still not as fast as any of Apple’s Max or Ultra chips, even the M1-series.

M4 Max

And finally, there’s the M4 Max (again, the fully enabled version, this one with 12 P-cores, 4 E-cores, 40 GPU cores, and 546GB/s of memory bandwidth). Single-core CPU performance is the biggest leap forward, jumping by between 18 and 28 percent in single-threaded benchmarks. Multi-core performance is generally up by between 15 and 20 percent. That’s a more-than-respectable generational leap, but it’s nowhere near what happened for the M4 Pro since both M3 Mac and M4 Max have the same CPU core counts.

The only weird thing we noticed in our testing was an inconsistent performance in our Handbrake video encoding test. Every time we ran it, it reliably took either five minutes and 20 seconds or four minutes and 30 seconds. For the slower result, power usage was also slightly reduced, which suggests to me that some kind of throttling is happening during this workload; we saw roughly these two results over and over across a dozen or so runs, each separated by at least five minutes to allow the Mac to cool back down. High Power mode didn’t make a difference in either direction.

CPU P/E-cores GPU cores RAM options Display support (including internal) Memory bandwidth
Apple M4 Max (low) 10/4 32 36GB Up to five 410GB/s
Apple M4 Max (high) 12/4 40 48/64/128GB Up to five 546GB/s
Apple M3 Max (high) 12/4 40 48/64/128GB Up to five 409.6GB/s
Apple M2 Max (high) 8/4 38 64/96GB Up to five 409.6GB/s

We shared our data with Apple and haven’t received a response. Note that we tested the M4 Max in the 16-inch MacBook Pro, and we’d expect any kind of throttling behavior to be slightly more noticeable in the 14-inch Pro since it has less room for cooling hardware.

The faster result is more in line with the rest of our multi-core tests for the M4 Max. Even the slower of the two results is faster than the M3 Max, albeit not by much. We also didn’t notice similar behavior for any of the other multi-core tests we ran. It’s worth keeping in mind if you plan to use the MacBook Pro for CPU-heavy, sustained workloads that will run for more than a few minutes at a time.

GPU performance in our tests varies widely compared to the M4 Max, with results ranging from as little as 10 or 15 percent (for 4K and 1440p GFXBench tests—the bigger boost to the 1080p version is coming partially from CPU improvements) to as high as 30 percent for the Cinebench 2024 GPU test. I suspect the benefits will vary depending on how much the apps you’re running benefit from the M4 Max’s improved memory bandwidth.

Power efficiency in the M4 Max isn’t dramatically different from the M3 Max—it’s more efficient by virtue of using roughly the same amount of power as the M3 Max and running a little faster, consuming less energy overall to do the same amount of work.

Credit: Andrew Cunningham

Finally, in a test of High Power mode, we did see some very small differences in the GFXBench scores, though not in other GPU-based tests like Cinebench and Blender or in any CPU-based tests. You might notice slightly better performance in games if you’re running them, but as with the M4 Pro, it doesn’t seem hugely beneficial. This is different from how it’s handled in many Windows PCs, including Snapdragon X Elite PCs with Arm-based chips in them because they do have substantially different performance in high-performance mode relative to the default “balanced” mode.

Nice to see you, yearly upgrade

The new MacBook Pros are all solid year-over-year upgrades, though they’ll be most interesting to people who bought their last MacBook Pro toward the end of the Intel era sometime in 2019 or 2020. The nano-texture display, extra speed, and extra RAM may be worth a look for owners of the M1 MacBook Pros if you truly need the best performance you can get in a laptop. But I’d still draw a pretty bright line between latter-day Intel Macs (aging, hot, getting toward the end of the line for macOS updates, not getting all the features of current macOS versions anyway) and any kind of Apple Silicon Mac (fully supported with all features, still-current designs, barely three years old at most).

Frankly, the computer that benefits the most is probably the $1,599 entry-level MacBook Pro, which, thanks to the 16GB RAM upgrade and improved multi-monitor support, is a fairly capable professional computer. Of all the places where Apple’s previous 8GB RAM floor felt inappropriate, it was in the M3 MacBook Pro. With the extra ports, high-refresh-rate screen, and nano-texture coating option, it’s a bit easier to articulate the kind of user who that laptop is actually for, separating it a bit from the 15-inch MacBook Air.

The M4 Pro version also deserves a shout-out for its particularly big performance jump compared to the M2 Pro and M3 Pro generations. It’s a little odd to have a MacBook Pro generation where the middle chip is the most impressive of the three, and that’s not to discount how fast the M4 Max is—it’s just the reality of the situation given Apple’s focus on efficiency rather than performance for the M3 Pro.

The good

  • RAM upgrades across the whole lineup. This particularly benefits the $1,599 M4 MacBook Air, which jumps from 8GB to 16GB
  • M4 and M4 Max are both respectable generational upgrades and offer substantial performance boosts from Intel or even M1 Macs
  • M4 Pro is a huge generational leap, as Apple’s M3 Pro used a more conservative design
  • Nano-texture display coating is very nice and not too expensive relative to the price of the laptops
  • Better multi-monitor support for M4 version
  • Other design things—ports, 120 Hz screen, keyboard, and trackpad—are all mostly the same as before and are all very nice

The bad

  • Occasional evidence of M4 Max performance throttling, though it’s inconsistent, and we only saw it in one of our benchmarks
  • Need to jump all the way to M4 Max to get the best GPU performance

The ugly

  • Expensive, especially once you start considering RAM and storage upgrades

apple’s-m4,-m4-pro,-and-m4-max-compared-to-past-generations,-and-to-each-other

Apple’s M4, M4 Pro, and M4 Max compared to past generations, and to each other

The M4 Max is also the only chip where memory bandwidth and RAM support changes between the low- and high-end versions. The low-end M4 Max offers 410GB/s of memory bandwidth, while the fully enabled M4 Max offers 546GB/s.

For completeness’ sake, there is a third version of the M4 that Apple ships, with nine CPU cores, 10 GPU cores, and 8GB of RAM. But the company is only shipping that version of the chip in M4 iPad Pros with 256GB or 512GB of storage, so we haven’t included it in the tables here.

Compared to the M2 and M3

CPU P/E-cores GPU cores RAM options Display support (including internal) Memory bandwidth
Apple M4 (low) 4/4 8 16/24GB Up to two 120GB/s
Apple M4 (high) 4/6 10 16/24/32GB Up to three 120GB/s
Apple M3 (high) 4/4 16 8/16/24GB Up to two 102.4GB/s
Apple M2 (high) 4/4 10 8/16/24GB Up to two 102.4GB/s

One interesting thing about the M4: This is the first time that the low-end Apple Silicon CPU has increased its maximum core count. The M1, M2, and M3 all used a 4+4 split that divided evenly between performance and efficiency cores, but the M4 can include six efficiency cores instead.

That’s not a game-changing development performance-wise (the “E” in “E-core” does not stand for “exciting”), but we’ve seen over and over again in chips from Apple, Intel, and others that adding more efficiency cores does meaningfully improve CPU performance in heavily multithreaded tasks.

CPU P/E-cores GPU cores RAM options Display support (including internal) Memory bandwidth
Apple M4 Pro (low) 8/4 16 24/48/64GB Up to three 273GB/s
Apple M4 Pro (high) 10/4 20 24/48/64GB Up to three 273GB/s
Apple M3 Pro (high) 6/6 18 18/36GB Up to three 153.6GB/s
Apple M2 Pro (high) 8/4 19 16/32GB Up to three 204.8GB/s

The M4 Pro is the most interesting year-over-year upgrade, though this says more about the M3 Pro than anything else. As we noted last year, it was a bit of an outlier, the only one of the M3-generation chips with fewer transistors than its predecessor. A small decrease in GPU cores and a large decrease in high-performance CPU cores explains most of the difference. The result was a very power-efficient chip, but also one that was more of a sidestep from the M2 Pro than a real upgrade.

apple’s-first-mac-mini-redesign-in-14-years-looks-like-a-big-aluminum-apple-tv

Apple’s first Mac mini redesign in 14 years looks like a big aluminum Apple TV

Apple’s week of Mac announcements continues today, and as expected, we’re getting a substantial new update to the Mac mini. Apple’s least-expensive Mac, the mini, is being updated with new M4 processors, plus a smaller design that looks like a cross between an Apple TV box and a Mac Studio—this is the mini’s first major design change since the original aluminum version was released in 2010. The mini is also Apple’s first device to ship with the M4 Pro processor, a beefed-up version of the M4 with more CPU and GPU cores, and it’s also the Mac mini’s first update since the M2 models came out in early 2023.

The cheapest Mac mini will still run you $599, which includes 16GB of RAM and 256GB of storage; as with yesterday’s iMac update, this is the first time since 2012 that Apple has boosted the amount of RAM in an entry-level Mac. It’s a welcome upgrade for every new Mac in the lineup that’s getting it, but the $200 that Apple previously charged for the 16GB upgrade makes an even bigger difference to someone shopping for a $599 system than it does for someone who can afford a $999 or $1,299 computer.

The M4 Pro Mac mini starts at $1,399, a $100 increase from the M2 Pro version. Both models go up for preorder today and will begin arriving on November 8.

A brand-new design for a little box

The new Mac mini is larger than the Apple TV by a bit—5×5 inches instead of 3.66×3.66 inches—but its proportions are roughly similar. That makes its footprint significantly smaller than the old mini (and the current Studio), which was 7.75×7.75 inches. But it’s also a fair bit taller: 2 inches, up from 1.4 inches.

Like the Studio, it’s made primarily of aluminum and has a pair of 10 Gbps USB-C ports on the front, plus an indicator light and a headphone jack for connecting headphones or speakers. On the back, it sheds all of its remaining USB-A ports in favor of Thunderbolt/USB-C ports (note that, like some Mac Studio models, the ports on the back have Thunderbolt capabilities and the ones on the front don’t). Compared to the old M2 mini, this is a net gain of one rear Thunderbolt port, but you’re giving one up compared to the M2 Pro Mac mini—the extra ports on the front should make up for this, but it’s worth noting if you have something connected to every single Thunderbolt port on your current box. All Mac mini models still include a gigabit Ethernet port and a full-size HDMI port, so USB-A is the only port you’ll need a dongle for that you didn’t need one for before.

Apple’s newest iPhones and Apple Watches don’t come out until later this week, but the rumor mill is already indicating that Apple is planning a product announcement for October to refresh some of the products that didn’t get a mention at the iPhone event. Apple scheduled its release calendar similarly last year, when it announced and released new iPhones in September and then launched the first wave of M3 Macs around Halloween.

Bloomberg’s Mark Gurman believes that the event will mainly focus on the first wave of Macs with M4 processors, following the standard M4’s introduction in the iPad Pro earlier this year. As he has reported previously, he expects new MacBook Pro models with the M4 and “pro-level M4 chip options,” presumably the M4 Pro and M4 Max. He also expects an M4 version of the 24-inch iMac.

But the most interesting of the new Macs will still be the redesigned Mac mini, which hasn’t gotten an M3 update at all and has been using the same basic external design since 2010. This Mac mini is said to be closer in size to the Apple TV than the current mini, but still uses an internal power supply so that owners won’t have to wrangle a power brick. At least some of the current device’s ports will be replaced by USB-C and/or Thunderbolt ports, something that MacRumors apparently confirmed earlier today when they found a reference to an “Apple silicon Mac mini (5 ports)” in an Apple software update (some of those ports are reportedly on the front of the device, a nice Mac Studio design upgrade that I’d like to see on a new Mac mini).

The “five port” descriptor does imply that there will be another model with either more or fewer ports—Apple used similar terminology to distinguish the two- and four-port versions of some MacBook Pro models in the Intel days. The current M2 Mac mini models have fewer ports than the models with the M2 Pro chip, because the more powerful processor also has more I/O capabilities—assuming we get one Mac mini with an M4 and an upgraded model with an M4 Pro, we’d expect the Pro version to have more ports.

Gurman says that other Mac models, including the Mac Studio, Mac Pro, and MacBook Air, will see M4-series updates throughout 2025. Of those, the Mac Studio and the Mac Pro have gone the longest without an update—they’re all still using M2-series chips.

Apple is also said to be planning some new lower-end iPads for the October event—not the first time that Macs and iPads have shared billing for one of these late-fall product announcements. The $349 iPad 10 and the iPad mini have both gone over a year without any kind of hardware update; it seems likely that they’ll both get newer chips, if not significantly updated designs.

Apple reportedly plans updated M4 Mac mini that’s actually mini

What was “mini” in 2010 is not particularly mini in 2024.

Apple hasn’t updated its Mac mini desktop lineup since the beginning of 2023, when it added M2 and M2 Pro chips and discontinued the last of the Intel models. Bloomberg’s Mark Gurman reports that the update drought will end later this year, when the mini will skip right from the M2 to the M4, something he originally reported back in April.

But the mini will reportedly come with more than just new chips: it will also get a new, smaller design, which Gurman says will be closer in size to an Apple TV box (specifically, he says it may be a bit taller, but will have a substantially smaller footprint). The new mini could have “at least three USB-C ports,” as well as a power connector and an HDMI port.

This would be Apple’s first overhaul of the Mac mini’s design since the original aluminum unibody version was released back in June of 2010. That model did include a slot for a built-in SuperDrive DVD burner, something Apple dropped from later models as optical drives became less necessary, but the M2 Mac mini has the same basic design and the same footprint as that Core 2 Duo Mac mini introduced over a decade ago.

Intel and other PC makers have been releasing computers smaller than the Mac mini for years now, starting with Intel’s (discontinued, then handed off) NUC desktops and proliferating from there. Often, these systems would save space by including an external power brick, while the mini has always used an integrated power supply. But the Apple TV, also powered by Apple Silicon chips and also with an internal power supply, suggested that it was possible to design a physically smaller system without making that particular design compromise.

Though the design is changing, Apple’s general approach to the Mac mini is staying the same as it is now. There will be a base model with a regular Apple M4 processor in it, and an upgraded model with the yet-to-be-released M4 Pro in it to help bridge the gap between the low-end mini and the more powerful Mac Studio. If the new mini has dramatically fewer ports than current models, that would also be a point of differentiation, though hopefully it would continue to include enough USB-C ports to support multiple external monitors along with other accessories.

Gurman doesn’t know whether Apple will change the pricing of the Mac mini to go with the new design, though he does think the new mini “may be cheaper to make.”

The new Mac minis will reportedly be available later in the year, though the M4 Pro models could be announced or released later than the standard M4 models. Gurman says that new iMac and MacBook Pro models with M4-series chips could release “as early as this year,” while M4 MacBook Airs would wait for the spring of 2025, and Mac Studio and Mac Pro desktops wouldn’t be updated until “the middle of next year.”

The M4 chip was introduced in this year’s iPad Pro refresh, just a few months after the launch of the M3; this was the first time one of Apple’s M-series processors debuted in anything other than a Mac.

M4 iPad Pro review: Well, now you’re just showing off

Samuel Axon

The new iPad Pro is a technical marvel, with one of the best screens I’ve ever seen, performance that few other machines can touch, and a new, thinner design that no one expected.

It’s a prime example of Apple flexing its engineering and design muscles for all to see. Since it marks the company’s first foray into OLED beyond the iPhone or Watch, and the first time a new M-series chip has debuted on something other than a Mac, it comes across as a tech demo for where the company is headed beyond just tablets.

Still, it remains unclear why most people would spend one, two, or even three thousand dollars on a tablet that, despite its amazing hardware, does less than a comparably priced laptop—or at least does it a little more awkwardly, even if it’s impressively quick and has a gorgeous screen.

Specifications

There are some notable design changes in the 2024 iPad Pro, but really, it’s all about the specs—and it’s a more notable specs jump than usual in a couple of areas.

M4

First up, there’s the M4 chip. The previous iPad Pro had an M2 chip, and the latest Mac chip is the M3, so not only did the iPad Pro jump two whole generations, but this is the first time it has debuted the newest iteration of Apple Silicon. (Previously, new M-series chips launched on the Mac first and came to the iPad Pro a few months later.)

Using second-generation 3 nm tech, the M4’s top configuration has a 10-core CPU, a 10-core GPU, and a 16-core NPU. In that configuration, the 10-core CPU has four performance cores and six efficiency cores.

A lower configuration of the M4 has just nine CPU cores—three performance and six efficiency. Which one you get is tied to how much storage you buy. 256GB and 512GB models get nine CPU cores, while 1TB and 2TB get 10. Additionally, the two smaller storage sizes have 8GB of RAM to the larger ones’ 16GB.

This isn’t the first time Apple has tied RAM to storage configurations, but doing that with CPU cores is new for the iPad. Fortunately, the company is upfront about all this in its specs sheet, whereas the RAM differentiation wasn’t always clear to buyers in the past. (Both configurations claim 120GB/s memory bandwidth, though.)

Can the M4 help the iPad Pro bridge the gap between laptop and tablet? Mostly, it made me excited to see the M4 in a laptop.

Samuel Axon

Regardless of the specific configuration, the M4 promises substantially better CPU and GPU performance than the M2, and it supports hardware-accelerated ray-tracing via Metal, which some games and applications can take advantage of if developers put in the work to make it happen. (It looked great in a demo of Diablo Immortal I saw, but it’s unclear how often we’ll actually see it in the wild.)

Apple claims 1.5x faster CPU performance than the M2 and up to 4x faster graphics performance specifically on applications that involve new features like ray-tracing or hardware-accelerated mesh shading. It hasn’t made any specific GPU performance claims beyond those narrow cases.

A lot of both Apple’s attention and that of the media is focused on the Neural Engine, which is what Apple calls the NPU in the M-series chips. That’s because the company is expected to announce several large language model-based AI features in iOS, macOS, and iPadOS at its developer conference next month, and this is the chip that will power some of that on the iPad and Mac.

Some neat machine-learning features are already possible on the M4—you can generate audio tracks using certain instruments in your Logic Pro projects, apply tons of image optimizations to photos with just a click or two, and so on.

Apple

In a major shake-up of its chip roadmap, Apple has announced a new M4 processor for today’s iPad Pro refresh, barely six months after releasing the first MacBook Pros with the M3 and not even two months after updating the MacBook Air with the M3.

Apple says the M4 includes “up to” four high-performance CPU cores, six high-efficiency cores, and a 10-core GPU. Apple’s high-level performance estimates say that the M4 has 50 percent faster CPU performance and four times as much graphics performance. Like the GPU in the M3, the M4 also supports hardware-accelerated ray-tracing to enable more advanced lighting effects in games and other apps. Due partly to its “second-generation” 3 nm manufacturing process, Apple says the M4 can match the performance of the M2 while using just half the power.

As with so much else in the tech industry right now, the M4 also has an AI focus; Apple says it’s beefing up the 16-core Neural Engine (Apple’s equivalent of the Neural Processing Unit that companies like Qualcomm, Intel, AMD, and Microsoft have been pushing lately). Apple says the M4 runs up to 38 trillion operations per second (TOPS), considerably ahead of Intel’s Meteor Lake platform, though a bit short of the 45 TOPS that Qualcomm is promising with the Snapdragon X Elite and Plus series. The M3’s Neural Engine is only capable of 18 TOPS, so that’s a major step up for Apple’s hardware.

Apple’s chips since 2017 have included some version of the Neural Engine, though to date, those have mostly been used to enhance and categorize photos, perform optical character recognition, enable offline dictation, and do other oddities. But it may be that Apple needs something faster for the kinds of on-device large language model-backed generative AI that it’s expected to introduce in iOS and iPadOS 18 at WWDC next month.

The wait between the M1 and M2 and the wait between the M2 and M3 were each about a year and a half. With as few technical details as Apple has announced, it’s tough to know what to make of the faster turnaround between the M3 and M4. It could be that the M3 was behind schedule and the M4 was on time or ahead; it could also be that the M4 is a relatively modest architectural update to the M3. We’ll need to test the hardware ourselves to determine exactly how the M3 and M4 stack up to each other.

The fast introduction of the M4 makes it a little clearer why Apple might choose not to update devices like the Mac mini with an M3 chip. Either the M3 processor generation will be uncommonly short, or Apple plans to sell a mix of M3 and M4 devices this year.

What to expect from Apple’s May 7 “Let loose” event

On May 7, Apple will host a product announcement event at 9 am ET. Labeled “Let loose,” we expect it will focus on new iPads and iPad accessories.

We won’t be liveblogging the stream, but you can expect some news coverage as it happens. Below, we’ll go over our educated guesses about why Apple might be doing this.

Why hold an event now?

It’s unusual for Apple to host an event shortly before WWDC. New products debut at that event all the time, so if it’s just a faster chip and a nicer screen for the iPad Pro and iPad Air, why not wait until June?

We’re not completely sure what the answer is, but we can make educated guesses.

Apple has been criticized by commentators over the past few weeks for three things. First, iPads have not been selling well. Second: While the Vision Pro introduced a new product category that may grow over time, its initial launch didn’t sell that well. Lastly, Apple is perceived by many as way, way behind on generative AI tech, which is already transforming other companies. There have also been rumors that Microsoft might announce a new silicon that will be fiercely competitive with Apple Silicon for AI tasks, and Microsoft’s chips could be announced at a planned event between May 7 and the start of WWDC.

Given all that, our best guess is that Apple wants to focus its messaging—and the time window for that messaging—on the right targets without muddying the message by trying to address everything at once.

Talking about the iPad’s challenges while also preempting Microsoft with a new chip announcement could be Apple’s focus for this event. Getting those things out of the way now would allow WWDC and its new operating system announcements to focus heavily on AI, which is the bigger question the company is looking to answer.

What new iPads might look like

Given that an Apple Pencil is in the event’s promotional image—a much more explicit hint than Apple usually provides—there’s no question iPads will be a focus.

As is often the case these days, we have a plethora of leaks, supply chain reports, and, of course, insider reporting at sites like Bloomberg and The Information to give us a rough idea of what to expect from Apple’s new hardware.

iPad Pro

It’s likely that the star of the show will be a significant redesign of the iPad Pro for the 11-inch and 12.9-inch sizes.

Both are rumored to get OLED displays, a huge step up over the LCD display in the current 11-inch iPad Pro. The 12.9-inch iPad Pro has a MiniLED display, which competes directly with OLED in the consumer TV space, so it won’t be as big a leap for that device, but we can still expect better contrast and richer colors.

Apple reportedly plans M4 Mac mini for late 2024 or early 2025, skipping the M3

But this would be a faster turnaround time than we saw for the M3 or the M2.

Bloomberg’s Mark Gurman thinks that Apple’s M4 chips for Macs are coming sooner rather than later—possibly as early as “late this year,” per a report from earlier this month. Now Gurman says Apple could completely skip the M3 generation for some Macs, most notably the Mac mini.

To be clear, Gurman doesn’t have specific insider information confirming that Apple is planning to skip the M3 mini. But based on Apple’s alleged late-2024-into-early-2025 timeline for the M4 mini, he believes that it’s “probably safe to say” that there’s not enough space on the calendar for an M3 mini to be released between now and then.

This wouldn’t be the first time an Apple Silicon Mac had skipped a chip generation—the 24-inch iMac was never updated with the M2, instead jumping directly from the M1 to the M3. The Mac Pro also skipped the M1 series, leapfrogging from Intel chips to the M2.

But if the M4 does come out by the end of 2024, it would be a much faster turnaround than we’ve seen for other Apple Silicon chips so far. Roughly a year and a half passed between the introduction of the first M1 Macs in late 2020 and the first M2 Macs in the summer of 2022; about the same amount of time passed between mid-2022 and the late-2023 introduction of the first M3 Macs. If Apple holds to a more typical 18-month gap between the first M3 Macs and the first M4 Macs, there’s still plenty of time for an M3-based Mac mini refresh to be released.

Apple last updated the Mac mini in January of 2022, replacing the M1 model with an M2 version and introducing a new variant with an M2 Pro chip that included more Thunderbolt ports, better external display support, and better CPU and GPU performance. Most of Apple’s desktops—both Mac minis, as well as the Mac Studio and Mac Pro—are still using Apple’s M2 chips, while all of the laptops and the iMac have gotten an M3 refresh at this point.

Gurman’s previous reporting on the M4 suggests that it will be an “AI-focused” chip series, which probably means that it will beef up the processors’ Neural Engine to power the on-device generative AI features that are expected to come with iOS 18 and Apple’s other major operating system updates this year. Apple already has a head start on the PC ecosystem in this respect—all of the M-series chips and A-series chips going all the way back to 2017’s A11 Bionic have included a version of the Neural Engine. Intel and AMD’s processors have only begun to include similar neural processing units (NPUs) within the last year or so.

Gurman hasn’t reported on the M4 series’ specifications, but he has said it will include at least three performance tiers: a base model codenamed “Donan,” a midrange version codenamed “Brava,” and a high-end model codenamed “Hidra.” It remains to be seen which of these chips would replace the Pro, Max, and Ultra processors in current-generation M2 and M3 Macs.
