I'lll just continue to use Parallels Desktop to run releases of macOS earlier than Big Sur on my Monterey Mac, because I absolutely need to! I have decided to abandon the notion, only because I believe that my Mac isn't powerful enough to actually drive the system, thanks to the underpowered integrated graphics on my machine. I can't rely on macOS-on-macOS emulation with Parallels Desktop 17.1.4 (51567). Reducing transparency, reducing motion and increasing contrast in the guest OS (Settings > Accessibility > Display) actually tends to help by making the performance of Metal emulation better by making less demands on the GPU, but these tricks only go so far if an application makes great demands on the GPU, the emulation falters, and causes applications to start displaying malfunctions, or get terminated (if the system survives the problems in the first place).

However, there are some things which tend to ease the congestion on the GPU.
Parallels desktop for mac support update#
Just recenltly, Visual Studio Code for Mac has stopped working (it was working at some point a few months ago, but a recent update has now broken this), and Microsoft Teams has always been unrealiable, both because the window contents cannot be rendered properly in the guest OS. I have to concede that I cannot make much use of macOS as a guest OS on my Mac, only because the larger apps like to malfunction or crash in the guest OS. I don't know whether the Metal support that Parallels Desktop/Apple system software offer either requires a larger, more powerful GPU, or is just plain broken. Running macOS Monterey on macOS Monterey on a MacBook Pro with Intel Iris 550 graphics is pretty abysmal.
