The internal HDD on my iMac (late 2015, OSX 10.15.7) crashed with I was upgrading the OS. Various rescue attempts did not work. I took it into the Genius Bar. They were able to erase and reformat the HDD, so it is now in the state of a new Mac.
Before the crash, I had all system files on the internal drive and all user date files (User directories) on an external drive. I have redundant backups of both the internal and external drives made using SuperDuper. The iMac will boot from the backup of the internal drive, but it is slow, so I want to use Migration Assistant to migrate the system back to the internal drive.
(I understand the internal drive may not be reliable. I’m just trying to get by until the Mac Minis are, hopefully soon, upgraded to M2s.)
Anyway, I’m wondering what the proper procedure is for migrating from two HDDs. Do I connect both the system disk and the data disk during the migration? Or do I connect the system disk only, then connect the data disk after the migration is complete?
If it helps, I am able to boot using the system disk only, then log into an admin account I kept solely on that drive, so I could likely get a working system migrating with only the system disk. The question is whether my user accounts would work properly if I waited until after the migration to connect the data drive.
Thanks in advance for any assistance.
