[Solved] Is there any tool yet that repairs APFS containers?
So it seems that something is wrong with the snapshots on the SSD of my MacBook Pro - migrated to APFS via normal upgrade going from 10.12 to 10.13. It is now on 10.14.2. (I’ve never previously needed to do a clean install.)
Disk Utility, via Recovery mode, gives me the error below. ie. It can’t fix it.
I have a suspicion I might need to do a clone, wipe the drive, then clone back?
There is not such a tool so far, so no upgrade to High Sierra or Mojave is recommended. This is a deal breaker!
OK - so I created/confirmed a Carbon Copy Cloner clone on an external SSD (this Samsung T5 is pretty good!), then used a USB stick with the Mojave installer to fully erase the internal drive, then install 10.14, then created a temporary user to allow a login that could perform the 10.14.2 update, then ran Migration Assistant to pull everything back from the external SSD.
All went pretty well, though I think the existence of the "temporary" user account, which meant my usual account was created with id 502 rather than 501, caused Little Snitch to revert to "factory" rules.
I have run Disk Utility First Aid and it now completes successfully (as below).
Tip/Discovery: First Aid seems to now allow repairs to be run on the current startup disk but says that it will "freeze" other apps while it is doing it !??!
