Dead characters on iMac Mojave, NOT keyboard-related












2















2002 iMac running Mojave with Apple wireless keyboard



Today, a cluster of characters on the right side of the keyboard (7 8 9 u i o j k l m .) quit working, both caps and lowercase.



To narrow down the problem, I replaced the keyboard with a spare and re-booted. The issue remained, leading me to believe it's not a keyboard problem.



I enabled the keyboard viewer and all keys work when clicked.



SOLVED — The problem was inadvertently enabling Mouse Keys.

  • 2002 iMac? Do you mean a 2012? Try booting in Safe Mode (hold shift while booting). If the issue goes away, it's something being loaded and intercepting those keys.

  • Lots of people have reported this in the Apple forums already, it seems some Mojave installs turn on Mouse Keys by default.

Sounds like you have accidentally activated Mouse Keys. Turn it off
