    Am I correct in assuming Catalina is not (yet) supported as a guest OS on Parallels 15.0? Parallels is running under Mojave 10.14.6.

    Parallels Desktop 15 can currently utilize macOS Catalina as a VM, with support for Catalina as a host operating system.

    Hmmm, then something is amiss. After installing, the macOS (Catalina) window hangs but with 200% processor usage. The screen colored like dark ode. I thought it may be the external monitor so disconnected that but still no joy. Still hangs.

    Reset and it now is running. Should have thought of that before!

    Is the Guest OS fast? It is very slow for me...

    Seems reasonably responsive to me. I've assigned 4 processors and 4 GB to the VM. Installed the VM to see what Catalina is like. Personally, I'm staying with Mojave since I don't want to spend the money needed to upgrade a lot of infrequently used but occasionally needed apps.

    I missed the fact that your host OS is Mojave. I am on Catalina as host (and guest) - unfortunately cannot go back to Mojave because I am on the 16" MBP.

    Fusion makes it simple to test nearly any OS and app on a Mac TalkToWendys.

    I've running into the same issue: I have a Catalina VM on Catalina which is barely usable, even with 2 CPU, 8GB of virtual RAM.
    The UI is extremely sluggish, even opening a terminal takes 5 seconds.
    Just to note, I come from VMware Fusion and never seen something like this: the same VM configuration and software runs just fine :/
    I've generated my tech report [336029810] for you to see if there is anything weird.
