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

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.

Well, this is good news that makes me happy. I know a number of devs will be appreciative of this, even in its limited present-form. Presumably, we just need the march of time for older OSes to be supported (starting now with 15 and going forward, I mean – as in, they might not backport, but I don’t expect them to take 15 away when they ship 16).
