I've just bought a PS/2 to USB cable to use PS/2 PC keyboard (Compaq SK-2860 and Packard Bell 6301N) in my Mac (OS X 10.8.4) because my Mac's wireless keyboard doesn't work:
…but my Mac does not identify the keyboard. I've got this window:
…but when I press the key to the right of shift nothing happens.
The cable works in Windows XP, and Linux Ubuntu well. I've seen this similar question but please note my issue is related to a specific PC keyboard. What can I do?
