M2 Air won’t draw new buyers in, but if you like iPads, these do all you need.

  • In portrait mode. The 13-inch model is a little large for dedicated tablet use, but if you do want a gigantic tablet, the $799 price is appealing.

  • The Apple Pencil Pro attaches, pairs, and charges via a magnetic connection on the edge of the iPad.

  • In the Magic Keyboard. This kickstand-less case is still probably the best way to make the iPad into a true laptop replacement, though it’s expensive and iPadOS is still a problem.

  • The tablet’s USB-C port, used for charging and connecting to external accessories.

The iPad Air has been a lot of things in the last decade-plus. In 2013 and 2014, the first iPad Airs were just The iPad, and the “Air” label simply denoted how much lighter and more streamlined they were than the initial 2010 iPad and 2011’s long-lived iPad 2. After that, the iPad Air 2 survived for years as an entry-level model, as Apple focused on introducing and building out the iPad Pro.

The Air disappeared for a while after that, but it returned in 2019 as an in-betweener model to bridge the gap between the $329 iPad (no longer called “Air,” despite reusing the first-gen Air design) and more-expensive and increasingly powerful iPad Pros. It definitely made sense to have a hardware offering to span the gap between the basic no-frills iPad and the iPad Pro, but pricing and specs could make things complicated. The main issue for the last couple of years has been the base Air’s 64GB of storage—scanty enough that memory swapping doesn’t even work on it— and the fact that stepping up to 256GB brought the Air too close to the price of the 11-inch iPad Pro.

Which brings us to the 2024 M2 iPad Air, now available in 11-inch and 13-inch models for $599 and $799, respectively. Apple solved the overlap problem this year partly by bumping the Air’s base storage to a more usable 128GB and partly by making the 11-inch iPad Pro so much more expensive that it almost entirely eliminates any pricing overlap (only the 1TB 11-inch Air, at $1,099, is more expensive than the cheapest 11-inch iPad Pro).

I’m not sure I’d go so far as to call the new Airs the “default” iPad for most buyers—the now-$349 10th-gen iPad still does everything the iPad is best at for less money, and it’s still all you really need if you just want a casual gaming, video streaming, and browsing tablet (or a tablet for a kid). But the M2 Air is the iPad that best covers the totality of everything the iPad can do from its awkward perch, stuck halfway between the form and function of the iPhone and the Mac.

Not quite a last-gen iPad Pro

The new iPad Airs have a lot in common with the M2 iPad Pro from 2022. They have the same screen sizes and resolutions, the same basic design, they work with the same older Magic Keyboard accessories (not the new ones with the function rows, metal palm rests, and larger trackpads, which are reserved for the iPad Pro), and they obviously have the same Apple M2 chip.

Performance-wise, nothing we saw in the benchmarks we ran was surprising; the M2’s CPU and (especially) its GPU are a solid generational jump up from the M1, and the M1 is already generally overkill for the vast majority of iPad apps. The M3 and M4 are both significantly faster than the M2, but the M2 is still unquestionably powerful enough to do everything people currently use iPads to do.

That said, Apple’s decision to use an older chip rather than the M3 or M4 does mean the new Airs come into the world missing some capabilities that have come to other Apple products announced in the last six months or so. That list includes hardware-accelerated ray-tracing on the GPU, hardware-accelerated AV1 video codec decoding, and, most importantly, a faster Neural Engine to help power whatever AI stuff Apple’s products pick up in this fall’s big software updates.

The 13-inch Air’s screen has the same resolution and pixel density (2732×2048, 264 PPI) as the last-generation 12.9-inch iPad Pro. And unlike the 13-inch Pro, which truly is a 13-inch screen, Apple’s tech specs page says the 13-inch Air is still using a 12.9-inch screen, and Apple is just rounding up to get to 13.

The 13-inch Air display does share some other things with the last-generation iPad Pro screen, including P3 color, a 600-nit peak brightness. Its display panel has been laminated to the front glass, and it has an anti-reflective coating (two of the subtle but important quality improvements the Air has that the $349 10th-gen iPad doesn’t). But otherwise it’s not the same panel as the M2 Pro; there’s no mini LED, no HDR support, and no 120 Hz ProMotion support.

Issues seem to be related to security fixes made in Apple’s latest OS.

USB hubs, printers, Java, and more seemingly broken by macOS 14.4 update

A couple of weeks ago, Apple released macOS Sonoma 14.4 with the usual list of bug fixes, security patches, and a couple of minor new features. Since then, users and companies have been complaining of a long list of incompatibilities, mostly concerning broken external accessories like USB hubs and printers but also extending to software like Java.

MacRumors has a good rundown of the list of issues, which has been steadily getting longer as people have run into more problems. It started with reports of malfunctioning USB hubs, sourced from users on Reddit, the Apple Support Communities forums, and elsewhere—USB hubs built into various displays stopped functioning for Mac users after the 14.4 update.

Other issues surfaced in the days after people started reporting problems with their USB hubs, including some instances of broken printer drivers, unexpected app crashes for some Java users, and problems launching apps that rely on the PACE anti-piracy software (and iLok hardware dongles) to authenticate.

At least some of the problems seem localized to Apple Silicon Macs. In fact, iLok recommends running digital audio software in Rosetta mode as a temporary stopgap while Apple works on a fix. According to iLok, Apple has acknowledged this particular bug and is working on an update, but “[has] not indicated a timeline.”

The USB hub issue may be related to the USB security prompts that Apple introduced in macOS 13 Ventura, asking users to confirm whether they wanted to connect to USB-C accessories that they were connecting to their Mac for the first time. Some users have been able to get their USB hubs working again after the 14.4 update by making macOS request permission to connect to the accessory every time the accessory is plugged in; the default behavior is supposed to recognize USB devices that you’ve already connected to once.

Scanning Apple’s release notes or security update disclosures for the update doesn’t reveal any smoking guns, but many of the security bugs were addressed with “improved checks” and “improved access permissions,” and it’s certainly possible that some legitimate accessories and software were broken by one or more of these changes. The Oracle blog post about the Java problems refers to memory access issues that seem to be causing the crashes, though that may or may not explain the problems people are having with external accessories. The blog post also indicates that these bugs weren’t present in the public developer betas of macOS 14.4.

My desktop M2 Mac Studio setup, which is connected to a 4K Gigabyte M28U with a built-in USB hub, hasn’t exhibited any unusual behavior since the update, so it’s also possible that these issues aren’t affecting every user of every Mac. If you haven’t updated yet, it may be worth waiting until Apple releases fixes for some or all of these issues, even if you don’t think you’ll be affected.

M3 MacBook Air refresh boosts storage speeds for 256GB models

in a flash —

For the M2 Air, getting better storage speeds required a 512GB (or larger) SSD.

When Apple upgraded its Macs with the M2 chip, some users noticed that storage speeds were actually quite a bit lower than they were in the M1 versions. Both the 256GB M2 MacBook Air and the 512GB M2 MacBook Pro had their storage speeds roughly halved compared to M1 Macs with the same storage capacities.

Teardowns revealed that this was because Apple was using fewer physical flash memory chips to provide the same amount of storage. Modern SSDs achieve their high speeds partly by reading from and writing to multiple NAND flash chips simultaneously, a process called “interleaving.” When there’s only one flash chip to access, speeds go down.

Early teardowns of the M3 MacBook Air suggest that Apple may have reversed course here, at least for some Airs. The Max Tech YouTube channel took a 256GB M3 Air apart, showing a pair of 128GB NAND flash chips rather than the single 256GB chip that the M2 Air used. BlackMagic Disk Speed Test performance increases accordingly; read and write speeds for the 256GB M2 Air come in at around 1,600 MB/s, while the M3 Air has read speeds of roughly 2,900 MB/s and write speeds of about 2,100 MB/s. That’s roughly in line with the M1 Air’s performance.

For the other M3 MacBook Airs, storage speed should be mostly comparable to the M2 versions. Apple sent us the 512GB configuration of the 13- and 15-inch M3 Airs, and storage speeds in the BlackMagic Disk Speed Test were roughly the same as for the 512GB M2 Airs—roughly 3,000 MB/s for both reading and writing.

Though this appears to be good news for M3 Air buyers, it doesn’t guarantee that any given 256GB MacBook Air will come configured this way. Apple uses multiple suppliers for many of the components in its devices, and the company could ship a mix of 128GB and 256GB chips in different 256GB MacBook Airs based on which components are cheaper or more readily available at any given time. (The Max Tech channel speculates that a single 128GB NAND chip costs Apple more than a single 256GB NAND chip, though Max Tech doesn’t cite a source for this, and we just don’t know what prices Apple negotiates with its suppliers for these components.)

Though it’s nice that the M3 Air’s baseline storage speeds are increasing, it’s too bad that a new Air is still offering the same storage speed as the M1 Airs released over three years ago. It’s frustrating that Apple can’t improve storage speeds along with CPU and GPU performance, especially when the standard M.2 SSDs in PCs are getting faster and cost less money than what Apple sells in its Mac lineup.

Asahi Linux project’s OpenGL support on Apple Silicon officially surpasses Apple’s

Newest driver supports the latest versions of OpenGL and OpenGL ES.

Slowly but surely, the Asahi Linux team is getting Linux up and running on Apple Silicon Macs.

Enlarge / Slowly but surely, the Asahi Linux team is getting Linux up and running on Apple Silicon Macs.

Apple/Asahi Linux

For around three years now, the team of independent developers behind the Asahi Linux project has worked to support Linux on Apple Silicon Macs, despite Apple’s total lack of involvement. Over the years, the project has gone from a “highly unstable experiment” to a “surprisingly functional and usable desktop operating system.” Even Linus Torvalds has used it to run Linux on Apple’s hardware.

The team has been steadily improving its open source, standards-conformant GPU driver for the M1 and M2 since releasing them in December 2022, and today, the team crossed an important symbolic milestone: The Asahi driver’s support for the OpenGL and OpenGL ES graphics have officially passed what Apple offers in macOS. The team’s latest graphics driver fully conforms with OpenGL version 4.6 and OpenGL ES version 3.2, the most recent version of either API. Apple’s support in macOS tops out at OpenGL 4.1, announced in July 2010.

Developer Alyssa Rosenzweig wrote a detailed blog post that announced the new driver, which had to pass “over 100,000 tests” to be deemed officially conformant. The team achieved this milestone despite the fact that Apple’s GPUs don’t support some features that would have made implementing these APIs more straightforward.

“Regrettably, the M1 doesn’t map well to any graphics standard newer than OpenGL ES 3.1,” writes Rosenzweig. “While Vulkan makes some of these features optional, the missing features are required to layer DirectX and OpenGL on top. No existing solution on M1 gets past the OpenGL 4.1 feature set… Without hardware support, new features need new tricks. Geometry shaders, tessellation, and transform feedback become compute shaders. Cull distance becomes a transformed interpolated value. Clip control becomes a vertex shader epilogue. The list goes on.”

Now that the Asahi GPU driver supports the latest OpenGL and OpenGL ES standards—released in 2017 and 2015, respectively—the work turns to supporting the low-overhead Vulkan API on Apple’s hardware. Vulkan support in macOS is limited to translation layers like MoltenVK, which translates Vulkan API calls to Metal ones that the hardware and OS can understand.

Apple’s OpenGL support has been stuck at the 4.1 level since macOS 10.9 Mavericks was released in 2013. Since then, the company has shifted its focus to its proprietary Metal graphics API, which, like DirectX 12 and Vulkan, is a “low-overhead” API meant to reduce the performance overhead sometimes associated with older APIs like OpenGL. But despite declaring OpenGL officially deprecated in 2018, Apple has left its existing OpenGL implementation alone since then, never updating it but also maintaining support even as it has transitioned from Intel’s processors to its own CPUs and GPUs.

Rosenzweig’s blog post didn’t give any specific updates on Vulkan except to say that the team was “well on the road” to supporting it. In addition to supporting native Linux apps, supporting more graphics APIs in Asahi will allow the operating system to take better advantage of software like Valve’s Proton, which already has a few games written for x86-based Windows PCs running on Arm-based Apple hardware.

Though there are still things that don’t work, Fedora Asahi Remix is surprisingly polished and supports a lot of the hardware available in most M1 and M2 Macs—including the webcam, speakers, Wi-Fi and Bluetooth, and graphics acceleration. Other features, like Thunderbolt, running displays over USB-C, the system’s built-in microphone, and the Touch ID fingerprint sensors, remain non-functional. Asahi’s most recent update blog post, published in mid-January, highlighted HDMI support, support for DRM-protected websites via Google’s proprietary Widevine package, Touchbar support for the handful of Apple Silicon Macs that use one, and more.

As for the newest wave of M3 Macs, Asahi developer Hector Martin said in October 2023 that basic support for the newest chips would take “at least six months.” Among other things, the team will need time to support the M3 GPU in their drivers; the team also relies primarily on Mac mini models for development, and the M3 Mac mini doesn’t exist yet.

Apple's Vision Pro headset.

Samuel Axon

Apple’s Vision Pro went up for preorder this morning at 8 am ET. As expected, shipment dates for preorders quickly backed up to March as initial supply was accounted for. Regardless of whether you’re in for the start or taking a wait-and-see approach with Apple’s ultra-pricey new device, though, we have access to a little more information about the device than we did before thanks to updates to the Apple Store website.

The product page for Vision Pro reveals configurations and pricing, and a new specs page clarifies answers to some questions we’ve had for a while now.

You’ll find all the relevant new information below. We’ve also updated our “What to expect from Apple Vision Pro” roundup with new information from the specs page.

Hardware specifications

As previously rumored, the Vision Pro has a variant of the M2 chip with an 8-core CPU (4 performance cores and 4 efficiency), a 10-core GPU, and a 16-core NPU. It has 16GB of unified memory.

There’s also the new R1 chip, which Apple claims achieves “12‑millisecond photon‑to‑photon latency” and 256GB/s memory bandwidth.

As for the display, we didn’t learn too much new here. As Apple has stated before, the two displays push 23 million pixels combined. They support refresh rates of 90 Hz, 96 Hz, and 100 Hz, and support playback of 24 fps and 30 fps video. Apple claims 92 percent DCI-P3.

The specs page also reveals that Vision Pro supports AirPlay at up to 1080p on iPhones, Macs, Apple TVs, and AirPlay-capable smart TVs.

Storage comes in three configurations. The base 256GB model costs $3,499. Bumping up to 512GB adds $200, and going to 1TB adds another $200.

The device’s camera supports both spatial photo and video capture, and Apple lists the specs as an 18 mm, ƒ/2.00 aperture at 6.5 stereo megapixels.

Additionally, there are six world-facing tracking cameras, four eye-tracking cameras, a TrueDepth sensor, a lidar scanner, four inertial measurement units, a flicker sensor, and an ambient light sensor. The headset authenticates the user by looking at their iris.

On the audio front, we’re looking at a six-mic array for audio capture. Apple isn’t super specific on the specs page about the speakers, noting only that the device offers “spatial audio with dynamic head tracking” like AirPods Pro and “personalized Spatial Audio and audio ray tracing.” Vision Pro also supports low-latency, lossless audio with the second generation of AirPods Pro.

Connectivity options include Wi-Fi 6 and Bluetooth 5.3.

Apple promises two hours of battery life for “general use” and says video watching can be up to 2.5 hours. The specs page also clarifies that Vision Pro can be used while charging the battery, which is something Apple had previously stated but then confusingly removed from its online documentation. This page seems to settle that.

The headset weighs between 21.2 and 22.9 ounces (600–650 g) depending on the light seal and headband used. That doesn’t include the battery pack, which weighs 353 g. That means Apple made the headset substantially lighter by pushing the battery to a separate unit.

Accessories and additional purchase options

As with its other hardware products, Apple offers AppleCare+ for Vision Pro. It’s $499 for two years, or $24.99 per month for perpetual coverage.

That price might seem awfully steep, but Apple lists the repair fees for the device on its service page and repairs without AppleCare+ will be even pricier—up to $2,399, depending on what’s broken. Any damage to the front glass panel will cost $799 to fix.

There are also a few optional accessories or replacement components you can buy, including:

  • Apple Vision Pro Travel Case ($199) – A pill-shaped case that contains and protects the headset along with its attachments and battery.
  • Apple Vision Pro Battery ($199) – A replacement for the battery that comes with the headset. You could also buy one of these to double your capacity while traveling, like for a long flight.
  • Apple Vision Pro Light Seal ($199) – The soft part of the headset that conforms to your face when you put the device on your head. This includes two light seal cushions, each in a different size.
  • Apple Vision Pro Light Seal Cushion ($29) – This attaches to the end of the light seal, and is intended to be removed for cleaning. It’s available in four sizes: N, N+, W, and W+.
  • Apple Vision Pro Solo Knit Band ($99) – One of two variations of the band that keeps Vision Pro on your head. This is the version that simply wraps around the back of your head. It’s available in three sizes: small, medium, and large.
  • Apple Vision Pro Dual Loop Band ($99) – The version that wraps around both the back of your head and the top. This also comes in small, medium, and large.
  • ZEISS Optical Inserts ($99+) – Lens inserts for those who wear glasses, as glasses won’t fit inside the device. Available in prescription and reader variations. You don’t need these if you wear soft contact lenses.
  • Belkin Battery Holder for Apple Vision Pro ($49.95) – A third-party accessory for either attaching Vision Pro’s battery to your belt or pants, or securing it with a cross-body strap.
