Have spent the past day doing similar. Moving from 13” MBP to 11” MBA. THat means all my heavy files can’t fit. So they’re going on the home iMac. DATA! DUPLICATES! WHAT WILL I LOSE? STAY TUNED!
I had to offload over 400 GB to fit on the Mini’s internal drive. I will soon find out if the official “Movies” folder can be external. I’m glad I have backups galore.
Backups Galore. Wasn’t that a Bond girl?
