U key on keyboard not working, no spill or damage
one my key, the letter between Y and I (I can’t type coz this hey not working) is not working, there’s no spill or damage. help
iMac 21.5″, macOS 15.7
stuff can become defect without physical or moisture damage
if it was me then I would verify that was the case by if its not a macbook or sorts then test the keyboard with another computer, would not need to be a mac
otherwise I would try to login as guest and see if it works here
