Mark has been having issues where he can't do a time machine backup on his new M1 Mac. It gives him a "can't write a file" error. Does he have enough memory for it? Leo says it's not related to memory. It's likely a Time Machine issue. One of the reasons why Leo doesn't rely on Time Machine. Leo uses SuperDuper or ChronoSync to do a backup. RSync is native to the Mac, which ChronoSync harnesses. And SuperDuper is in beta on a bootable backup with the M1. So it's the way to go.
