So, I have just upgraded to PD13, on the latest High Sierra beta, and noticed that, if "Optimize full screen for games" is "on" then whenever I try to switch back to the main space (i.e. tme macOS desktop space) from the full screen Windows 10 VM, that macOS desktop space is filled with the same full screen Windows 10 VM. In other words, no more macOS desktop space, I have to shut down the Windows 10 VM in order to be able to do any macOS operation. Disabling "Optimize full screen for games" gets rid of this unwanted behavior.
Hi @MihaiE , Parallels Desktop for Mac will not support any Beta versions of Mac Os Please wait for the official release.
