Whenever I do an operation in Disk Utility the last day it seems that I end up with my APFS partitions set to an unknown partition type (
This has happened three times now both after extending APFS partitions, and after splitting a HFS partition and creating a new APFS partition. Once it changed the partition type of an APFS partition that wasn't even involved in the resize operation.
Every time this happens I'm forced to manually change the partition type back using e.g.
gdisk to make the system bootable again.
Is this a generally known bug in the community, or what's going on here? Why is it insistent on breaking the system partition after a resize?
- It has happened with Disk Utility in macOS 10.14 Mojave and 10.15 Catalina
- The resize operations were initiated by simply selecting trailing "free space" and removing it.
