Our discussion with Joe Kissell, the author of the fourth edition of Take Control of Backing Up Your Mac, continues with more examples of things that have changed in the world of backups. This time, Joe talks about what you can and can’t do with APFS snapshots, how to think about them, anda why they are a huge  benefit to data safety. Joe also touches on booting M1 Macs from external USB-C and Thunderbolt drives, and why they are not created equal. (Part 2) Today's MacVoices is sponsored by Upstart. Fair and fast personal loans.
