Keyboard failed after update 10.10.5 on iMac (2013)

Hello,

I'm trying to fix a problem with a keyboard that doesn't work after an update to 10.10.5 on a iMac (2013)

My father in law, just update his OSX version and now the keyboard doesn't work anymore.

I tried to help him, with different solutions I found on the forum:

I tried this:

1: Turn off the iMac, remove al devices and wait for 10 min and the turn everything on again

DID NOT WORK

2: Tried to update to El Capitain OSX, the install of the OSX was no problem, but the keyboard still doesn't work

3: I tried to reset the RAM, but I can't do this because I need a combinations of keys to do it (will not work when the keyboard doesn't work 😉 )

Is there anybody out there who can help me?? or better who can help my father in law 🙂

Best regards,

Jeroen

Wired or wireless keyboard?

If your wireless or USB keyboard doesn't work

Keyboard Doesn’t Work

Keyboard Keys Do Not Respond

Keyboard/Mouse – Troubleshooting Wireless

Reset an Apple Wireless Bluetooth Keyboard, Mouse or Trackpad (Troubleshooting Pairing and Other Common Problems)

Bluetooth devices become unresponsive

Bluetooth Interference Sources

Bluetooth Interference Sources (2)

Bluetooth Wireless Problems

If your Wi-Fi is capable of generating a 5 GHz signal, try that.

Restart the computer holding down the command - option/alt - P - R keys before the gray screen appears. Continue to hold until you hear the startup chime for the second time.

Reset NVRAM/PRAM

Hi Eric,

Thx for your reply.

The problem that I have is with a wired usb keyboard.

I have tried these:

If your wireless or USB keyboard doesn't work

Keyboard Doesn’t Work

Keyboard Keys Do Not Respond

But the problem still remained.

I want to reset the NVRAM, but I can't do that because I have to use a keyboard command 🙂 and that I just the problem.

I also tried to install El Captain, but the problem remaines

Do you have any other suggestions?

Is the any plist that I can delete?

Regards,

Jeroen

You are welcome. I didn't see a keyboard.plist for my iMac, but without a functioning keyboard, you can't access the User Library. Do you have access to another keyboard you can test?
