I have had several problems with Monterey but another one has now materialised. I don't use my magic keyboard much with my 2020 iMac as I prefer my MX Mac keyboard but I was trying to use it this afternoon. I realised that the numbers 789 and letters VIOJKLM don't work. When I connected the magic keyboard to my MacBook Air it worked perfectly. The letters are also missed out if I use the magic keyboard plugged into the iMac. Maybe connected to the problem but also my Magic Mouse is performing poorly with the cursor stopping for a few seconds every ten seconds or so. A weird one, not too sure what to do. I reinstalled Monetary the other day to try to cure some of the problems I have had so I don't know if I need to reinstall again?
