My favorite macOS Sequoia feature so far might be the old-timey Mac wallpaper

Combo wallpaper-screen saver is a walk down memory lane for classic Mac users.

I’m still in the very early stages of poking at macOS 15 Sequoia ahead of our customary review later this fall, and there are quite a few things that aren’t working in this first developer beta. Some of those, like the AI features, aren’t working on purpose; I am sure some of the iCloud sync issues I’m having are broken by accident.

I’ve already encountered a few functional upgrades I like, like iCloud support inside of virtual machines, automated window snapping (at long last), and a redesigned AirDrop interface in the Finder. But so far the change that I like the most is actually a new combo wallpaper and screen saver that’s done in the style of Apple’s Mac operating system circa the original monochrome Mac from 1984. It’s probably the best retro Mac Easter egg since Clarus the Dogcow showed up in a print preview menu a couple of years ago.

The Macintosh wallpaper and screen saver—it uses the animated/dynamic wallpaper feature that Apple introduced in Sonoma last year—cycles through enlarged, pixelated versions of classic Mac apps, icons, and menus, a faithful replica of the first version of the Mac interface. Though they’re always monochrome, the default settings will cycle through multiple background colors that match the ones that Apple uses for accent colors.

If you’re too young to be familiar (or if you were using MS-DOS in the mid-’80s instead of a Mac), this Mac theme hearkens back to the days before Mac OS (then Mac OS X, then OS X, then macOS) was called Mac OS. The first seven versions of the software were simply called System or System Software, all the way up through 1991’s System 7. The Mac OS name didn’t appear until the System 7.5.1 update in 1995, and the name was formally changed in the 7.6 update in 1997 (OS updates were obviously released at a more leisurely pace back then).

If you want to poke at a live, interactive version of the monochrome System Software, developer Mihai Parparita’s Infinite Mac project hosts classic System, Mac OS, and NeXTStep versions that will all run in a browser window using ports of various emulators.

My only complaint is that now I want more of these screen savers. As a millennial, my exposure to Systems 1 through 6 was fairly minimal, but I’d definitely take a color version of the screen saver modeled on Mac OS 9, or an early Mac OS X version with shiny candy-colored Aqua-themed buttons and scroll bars.

Apple quietly improves Mac virtualization in macOS 15 Sequoia

It only works for macOS 15 guests on macOS 15 hosts, but it’s a big improvement.

We’ve written before about Apple’s handy virtualization framework in recent versions of macOS, which allows users of Apple Silicon Macs with sufficient RAM to easily set up macOS and Linux virtual machines using a number of lightweight third-party apps. This is useful for anyone who needs to test software in multiple macOS versions but doesn’t own a fleet of Mac hardware or multiple boot partitions. (Intel Macs support the virtualization framework, too, but only for Linux VMs, making it less useful.)

But up until now, you haven’t been able to sign into iCloud using macOS on a VM. This made the feature less useful for developers or users hoping to test iCloud features in macOS, or whose apps rely on some kind of syncing with iCloud, or people who just wanted easy access to their iCloud data from within a VM.

This limitation is going away in macOS 15 Sequoia, according to developer documentation that Apple released yesterday. As long as your host operating system is macOS 15 or newer and your guest operating system is macOS 15 or newer, VMs will now be able to sign into and use iCloud and other Apple ID-related services just as they would when running directly on the hardware.

This is still limiting for developers, who might want to run an older version of macOS on their hardware while still testing macOS 15 in a VM, or those who want to do the reverse so that they can more easily support multiple versions of macOS with their apps. It also doesn’t apply to VMs that are upgraded from an older version of macOS to Sequoia—it has to be a brand-new VM created from a macOS 15 install image. But it’s a welcome change, and it will steadily get more useful as Apple releases more macOS versions in the future that can take advantage of it.

“When you create a VM in macOS 15 from a macOS 15 software image… Virtualization configures an identity for the VM that it derives from security information in the host’s Secure Enclave,” Apple’s documentation reads. “Just as individual physical devices have distinct identities based on their Secure Enclaves, this identity is distinct from other VMs.”

If you move that VM from one host to another, a new distinct identity will be created, and your iCloud account will presumably be logged out. This is the same thing that happens if you backup a copy of one Mac’s disk and restore it to another Mac. A new identity will also be created if a second copy of a VM is launched on the same machine.

Mac users hoping to virtualize the Arm version of Windows 10 or 11 will still need to look to third-party products for help. Both Parallels and VMware offer virtualization products that are officially blessed by Microsoft as a way to run Windows on Apple Silicon Macs, and Broadcom recently made VMware Fusion free for individuals.
