I just completed my first ever Time Machine migration… or I thought I had.
I just got a new 1TB SSD & PCIe mount to lift my speeds up to full SATA III on an old Mac Pro normally limited to SATA II speeds.
I decided now would be time to clean up a bit so I'd do a fresh, clean install then migrate, rather than my usual trick of simply cloning it with Carbon Copy Cloner.
All appeared to go well. Install went smoothly, I was presented with the Migration tool & asked it to migrate from my Time Machine drive [also internal, last updated only 30 minutes prior]. I selected everything - about 500GB, half full drives, old & new.
It busied itself with the copying for a good while, then presented a very long list of esoteric things it couldn't copy - no explanation was given. The list was far too long to give more than a cursory glance to. I thought I could probably get away with missing a few bits, so long as the main stuff had transferred, so I stepped on to the next part of setup, signing into iCloud etc [there was no other choice but to accept the list of fails, it was OK or nothing.]
On finally arriving at the desktop I quickly realised that absolutely nothing had been migrated at all. No Apps, no docs, no music, pictures… zero.
So, I'm currently making a new CCC clone.
Anyone have any idea what may have gone wrong, so much so that absolutely nothing happened after a good half hour of 'being busy'?
Mac Pro 5,1 Mojave 10.14.6 [both old & new installs] 2 x 1TB SSD, 4 other HDs inc one for Time Machine.
I've now tried this perhaps 7 times using different strategies. The slimmest version was a brand new Time Machine with a single manual backup, restoring just one account to a wiped SSD. No other drives connected. Both drives on the regular SATA bus, no PCIe card. SIP disabled.
Single file restoration is fine now, though was really broken before I disabled SIP. All apps showed as 'grey with a no-chance sign'.
Migration just will not work, neither will a direct Restore from Time Machine to a blank drive.
