Re: What is the Author actually asking for?
Windows 10 VMs on VMware Fusion (note VMware is not "VMWare") or Parallels run really well. Catalina as a VM on VMware Fusion or Parallels is dogshit. It's uselessly bad. I have VMs for every macOS/OS X version that supports running in a VM and Catalina has never run correctly in a VM in any version, beta to today. Native Apple applications (e.g. Music, TV, News) take minutes to respond. I thought it was intentional, but macOS 11 Big Sur beta runs pretty well in VM. Catalina is just terrible.
