My MacBook Pro 2018 has had lots of trouble. It's the second, the first one locked me (and everyone else) out permanently.
In short.
- Struggling with getting Bootcamp to work, I ended up with some sort of encryption warnings on the fstree during Disk First Aid
- I fixed that g creating another container and cloning the drive.
- I then erased the original container, cloned the drive back and upgraded it to Mohave Beta.
The Beta resolved all my BootCamp installation issue after about 1½ days of trying stuff.
But now I get an error trying to change the Startup Security Settings in the recovery partition - Recovery is trying to change system settings, no administrator was found.
There are two admins on each partition. None of them have changed from previous incarnations.I hoped the system was smart enough to add new admins, if I added another admin user. Not so.
I finally got the darned thing to work overall. Only one more day left installing apps and tweaking the whole thing. I will not do wipe and Network Recovery, which killed my first MacBook so I had to send it back.
Anybody from Apple here? I am hesitant to call support, they will ask for a wipe and restore, even if it kills the machine as it did last time.
