Based on reports from others (reporting success when cloning an m-series Mac with CCC), I tried creating a bootable backup on an old drive -- and failed.
My hardware:
2021 MacBook Pro 14" (base model).
OS 12.2
The target drive is an OLD 40-pin platter based drive (P-SATA or IDE?), in a Rosewill 40-pin to USB2 case.
The drive mounts and erases to APFS without problems.
I ran CCC using the "Legacy" option.
The clone takes a while, but completed successfully (as reported by CCC).
I then shut down and re-booted to "startup options", and the backup drive shows as bootable in the choice of startup drives.
However... the boot will begin... and then eventually "stall"...and then... it suddenly "finishes up", but to the INTERNAL drive, and presents a "your computer was restarted because of a problem" alert.
I also tried starting the process from scratch, this time using SuperDuper instead -- and the results are the same.
The "Data" portion of the clone gets done as intended.
But the drive won't successfully boot.
I'm thinking that this might be due to one or more factors:
- old 40-pin parallel ATA type hard drive
- controller on the drive
- controller in the Rosewill enclosure
- a combination of the above, or something else.
Guess I'll have to try either an SSD or a SATA-based drive.
Perhaps the new OS's can't handle older drive technology...
