Like others, I am debating how best to migrate over to my new iMac. I’m coming from a 2007 iMac, used extensively, and no doubt containing all sorts of unused detritus, orphan files, and orphans of orphans. 12 years is a long time in the life of a computer. So Time Machine back up, iCloud Backup, Carbon Copy, and manual file transfer? Some sort of combination of these? I honestly don’t know how I will proceed. Very open to thoughts and suggestions. Thanks.
