Here’s an APFS (Encrypted) volume that isn’t encrypted, and an unencrypted volume with FileVault active. Something must be wrong.
diskutil
Should you run First Aid on every volume, then each container? And why can it return status 65? How can you work around that?
Once, you could run diskutil to ‘fix’ broken permissions in your Home folder, then it was replaced by repairHomePermissions in Recovery. Apple no longer documents this, but it’s still there. Should you use it?
Apple could have chosen to make APFS open source or to document it fully, to help third parties develop maintenance tools. It chose not to, but Disk Utility still doesn’t work as it should.
APFS backup disks offer different possibilities for adding volumes for your own use, alongside the backup volume. How do you decide what’s best?
