I started out creating a macOS 15.5 guest on my macOS 15.5 host (an Intel 16" 2019 MacBook Pro, MacBookPro16,1). This worked fine. Then I copied over the InstallAssistant.pkg file from a macOS 26 Beta 3 full installer, ran this to copy the full installer to /Applications, then ran "Install macOS 26 Beta". This worked, after a fashion. But it was *very* slow, and the VM I ended up has a badly broken UI and is very unstable. The Desktop is solid grey, and the Dock is completely missing. I can do things there, but it's *incredibly* slow -- it took more than an hour to run the XCode 16 Beta 3 for the first time, and another hour to install the Beta 2 Commandline Tools. The VM often hangs or crashes. So ... As I understand it, Parallels still supports macOS guests on Apple Intel boxes. Are they working to fix these problems? Will we be able to count on running the macOS 26 release as a guest in a Parallels VM on an Intel box?
