My Z key isn’t working and now weird characters come up when i type random keys fast.
PLS HELP
Have you checked there is no dust, crumb ? You could try to use a vacuum cleaner to bl ow air and try to remove.
What else do you want other developers to do ?
Replace the z key !!!! Or go to a repair shop.
In any case, that's the wrong forum. This is for developing apps, not hardware or software issues. You'd better post there: https://discussions.apple.com/welcome
