So is this the actual bug then? Because I just used Disk Utility (in Tahoe) to check and repair an AFPS volume and it appeared to do the right thing, with the caveat that I had to "eject" it manually since Disk Utility complained that stuff was using it. Presumably, booting into macOS Recovery would've worked, too.

If the author's reading, is there a way we can help amplify any existing bug report(s)?
