Some keys not working on iMac

Hardware & Accessories

My family owns an iMac which I use on some occasions. All the letters and other keys work except for the left control key and the row of numbers. The keyboard is not broken and I have tried plugging it back in, it is not a Bluetooth keyboard. If I use any diagnostic feature to check if it is software related, will voiceOver work in any special start up mode?
It is possible some settings have been changed, a family member was deleting their emails, but what could those settings be?

It might be the keyboard then. If you can find another key board to test with even a bt one. or try it in windows if you have a boot camp set up installed. If it fails in both chances are the keyboard is broken.

Most obvious feature I can suggest is to turn on voice over's key describer mode (vo +k) an descape to exit.

If your family members are sighted, do these keys work for them?

Good luck!

I agree, it sounds like a hardware problem or a very strange software bug. I can't recall seeing any setting in osX's system preferences regarding turning off / blocking some keys. Try to find another USB keyboard and test with it.

Thanks for the responses so far. I contacted Apple support but need sighted assistance to see if the keys light up using a feature to test this. I have to go in the setting to remember how to get to it.
