Has anybody been able to create a Catalina boot USB from an OSX VM running on unraid (i'm trying to set up a hackintosh but have no access to a legit mac)?
I have managed to deploy High Sierra in a VM with a USB thumb stick passed through and accessible but whenever I try to format it it fails with this error:
POSIX: reports: The operation couldn't be completed. Invalid argument. Operation failed.
I've tried a few USB sticks which I know are working fine.
