I am running Catalina beta on several systems. VMware Fusion 11 is fine after setting up the various privacy exceptions and allowing the KEXTs.
BootCamp on a partition of the main disk is fine.
However, one of my system uses a complete disk for BootCamp. It works with SIP enabled on Mojave and earlier following the procedure in KB 2151780 - VMware Knowledge Base
However, under Catalina it fails with SIP enabled. This is most likely due to the fact that a PrivilegedHelperTool com.vmware.DiskHelper is moved to the /Library/PrivilegedHelperTools folder, but cannot be enabled for Full Disk access under Privacy settings.
Has anybody found a work around?
VMware - I would be glad to test whatever you have to offer.
I generally like to keep SIP enabled.
