Section of my wireless keyboard stopped working.
7,8,9,U,I,O,J,K,L,M and the . keys stopped responding. The comma key works just fine though. I’ve followed the “Systems Preferences” advice on other posts and disconnected and repaired (interestingly the code to re-pair it included keys which don’t respond and were accepted just fine when pressed for that purpose.) Still no luck. Any other ideas anyone?
