As the title says, I'd like to run a macOS 27 VM on my Mac (the host is on macOS 26.5.1) in order to test my apps without having to update my host to a beta. My virtualization app of choice (VirtualBuddy) fails on installation when I use the restore image for macOS 27.0 (26A5353q) from the developer website.
The developer of VirtualBuddy believes this is a macOS limitation (https://github.com/insidegui/VirtualBuddy/discussions/683). (I filed FB22977958, but I'm not sure if they filed their own bug.)
Is there a workaround? It'd be very nice to have access to this during WWDC week. Usually I'd look for device support files on the developer website for download and/or install the Xcode beta first, but I've already installed the Xcode beta and there don't seem to be any device support files available.
