Again lost the date in menubar clock in the latest beta (6). Anyone has terminal command line to restore the date? It was posted in an early thread on Big Sur back in June but I can't find them....
Fixed it for now. Had to fire up terminal and use the following. The changes didn't take effect until I opened up the Date and Time preference panel and selected the Time Zone tab. I rebooted and the changes seemed to stick. If you don't want seconds you can omit the ':ss' as shown below.
With seconds:
defaults write com.apple.menuextra.clock "DateFormat" "EEE MMM d h:mm:ss"
Without seconds:
defaults write com.apple.menuextra.clock "DateFormat" "EEE MMM d h:mm"
