Apple wired keyboard not working
I have a Apple full size wired Keyboard model no. 1243, which I use with an iMac Mid 2011, running 10.13.6, and it has suddenly stopped working.
However if I plug it into my MacBook Pro Retina, Mid 2012 running 10.14.4, the keyboard works perfectly.
I have tried all 4 USB slots on the iMac, which work with other peripherals, so I am stumped!
Any ideas?
