Hi, I updated my MacBook Pro (late 2016) this morning from Big Sur beta 3 to beta 4 and now almost all icons in the menu bar and all menus are lost/disappeared: All I can see are empty boxes which should contain the menu lists.
I did a PRAM reset and had Disk Utility "repair" all volumes (but it did not find any errors or problems). Before I re-install the entire system with 1 TB of data (taking some 8-10 hours): Does anyone have any idea? Or did this happen elsewhere and I/we may hope that Apple will provide a fix soon?
