MacVoices #20211: Joe Kissell Takes Control of Big Sur (2) The second part of our conversation with Joe Kissell about Take Control of Big Sur focuses on how to get the most out of the new version of macOS, from the more iOS-influenced look to the features that you won’t be able to access until you buy an Apple Silicon-based machine. Joe discusses some of the updated productivity features, why you don’t have to upgrade to Big Sur to enjoy the latest privacy protections in Safari, and why he is excited by the return of the startup chime.
