I have an OSstatus -22 error with Catalina while trying to restore any ISO/DMG to a USB flash drive using Disk Utility. I can use the terminal option just fine, but does anyone know of a reason why this error appears? I never had it under Mojave. Been looking for a solution to flash old PowerPC images in Apple Partition Format; used to work fine without any 3rd party tools. This is the closest solution I came to: Disk Utility fails with OSStatus error 22 during cloning/recovery operation
Thanks!
