Wireless keyboard not working properly after upgrade to OS X Yosemite
i've recently updated my 2011 iMac to OS X Yosemite. After the Mac was done some keys of my keyboard stopped working. The entire bottom row stopped working, zxcvbnm,. -keys aren't working either together with the backspace, caps lock and the tab -keys.
All other keys seem to work fine. I've tried resetting the pram or nvram meetings and dmc settings but without any result. Only option was using a windows usb keyboard....sadly.
I hope anyone has an idea how to fix this. It was not damaged in any way.
