10.12.6 to 10.13.6 becoming a nightmare on MacPro mid 2010 despite following instructions
I put OSX 10.13.6 on an SSD with a firmware update, and IT WORKED!
Then I moved that SSD to another bay (native SATA) and it does NOT work.
I returned the SSD to the original bay and it does NOT work.
I tried to redo the update on that SSD from a 10.12.6 disk as before this way:
https://support.apple.com/kb/DL1970?locale=en_US
and got the message below, even tho the failing disk IS 10.13.6,
even tho I was on 10.12.6 the first time the upgrade succeeded,
Then I went to the app store and tried and got the next message below.
The "250" is APFS (Case-insensitive). This is the 10.13.6 that wont boot anymore.
The "240" is Mac OS Extended, 10.12.6 and I get the same message.
Dont know what to do now, and I dont know how to change the journaling
even when looking at disk utility. Any advice appreciated. Thanks
Mac Pro, macOS 10.12
