MacVoices #20210: Joe Kissell Takes Control of Big Sur (1) Joe Kissell helps you get up and running with Apple’s latest version of macOS in Take Control of Big Sur.

Joe takes us through some things that you should be aware of before, during, and after the upgrade, including a potential limitation on being able to boot from a backup, and a caveat regarding Time Machine.
