unfortunately the problem is still the same with Big Sur 11.2.2 - the wireless function between my MacBook Pro and my HP Deskjet has stopped - nothing that Apple has suggested has fixed the problem. I'm sure it is simple enough to sort - Please Apple, can you fix this issue with Big Sur 11.2.2 ASAP - it is proving to be a disaster and a total hindrance to my work. Thank you.

Oh dear Apple - Big Sur is a bit of a disaster. The whole point of Macs and MacBook Pro is the speed and efficiency. However, Big Sur should be called Big Slow. My MacBook Pro is now operating so slowly it is like going back to using a PC - probably even worse. On top of that, the MacBook keeps crashing - several times a times an hour - often two or three times in quick succession. It is very frustrating and very annoying. Please get this problems identified in this thread of feedback about Big Sur sorted as soon as possible - i.e. at your earliest convenience. It is making using a Mac a total misery at the moment. Big Sur has not been a successful upgrade of the OS.
