Transfer of Certain Files to a new iMac
I want to change from my iMac 21.5" (Late 2015) to a new iMac with the Apple M1 chip. I don't want to transfer all my current files, just certain ones. How do I select certain files and photos for the transfer ? Can I use a Thumb drive to copy for my current iMac and reload in the new machine ?I assume this might be laborious.
Thank you for your help.
