I originally purchased the base M1 Air. However, I needed more memory so I bought the 512/16 M1 Air. I will return the base model for a refund. The 16GB RAM Air arrived yesterday - well ahead of schedule. What's the best way to transfer my files/settings/everything from one computer to the other? Migration Assistant? Time Machine? CCC? I would like a good, clean install, but retain all of my settings.
