migration
How can I use migration assistant to transfer files from a backup on an external hard drive? I didn't use Time Machine to back up, but rather Acronis true image for Western Digital. The backups are TBX files and they aren't recognized. When I plugged the HD into the Mac, it started a Time Machine backup. Migration assistant doesn't recognize the drive.
FWIW I just updated my 2013 Mac to Monterrey using OpenCore Legacy Patcher and erased the Mac in the process so it's like a new Mac.
