In case you were wondering, you can easily run macOS 15 in a VM by downloading the IPSW from developer.apple.com and using it to create a new machine in VirtualBuddy (https://github.com/insidegui/VirtualBuddy). Thanks @_inside for your continued work on this!

@chris @_inside Does this still have the limitation that you cannot use AppleID (…developing in Xcode, iCloud) withing the VM?
@hannesoid macOS 15 removed this limitation
@dayglojago @hannesoid Only on macOS 15 host.
