Yes, Lume supports running macOS Big Sur as a guest on Apple Silicon (M1 or later) hosts running Monterey or newer, as long as you’re using an ARM64 build of Big Sur.
However, App Store sign-in is currently not supported inside macOS VMs due to how Apple handles hardware entitlements and secure boot in virtualized environments.
That said, with macOS Sequoia, Apple has relaxed some constraints — you can now sign into iCloud inside a VM, which enables direct downloads of stable or beta Xcode installers without needing the App Store. More details here:
Thanks, but the issue is I don't need XCode.
It's a weird use case, I know - I need to be able to access App Store to download old versions of Apple's Motion/Final Cut Pro, ones that are only available for Big Sur.
If this is somehow possible, then I would really appreciate any tips, thanks!
