iMac inserting letters

I have an iMac that is inserting extra letters like this:

typing 1 or 6 inserts 16

typing q or y inserts qy

typing a or h inserts ah

typing z or nz inserts nz


The behavior is the same using either a Mac wireless keyboard or a Mac USB keyboard. It seems like a SW problem. Has anyone solved a similar problem?


iMac, macOS 10.12

Hi,


A Safe Mode boot delete some system caches that might help especially since the issue exists on multiple Macs.
