My keyboard keys keep dieing out on me on iMac OSX Yosemite 10.10.3
I can't type letters or numbers in any of my programs. The batteries are new and the Bluetooth is on. When I use the keyboard viewer the keys light up when I touch the keys on my keyboard but nothing gets typed. I've called Apple support and they can't figure it out. Ever since I updated to the new operating system (OSX Yosemite), I'm having so many issues- this one is by far the most frustrating. I know the keyboard is fine, because the delete, space bar and a few other keys still work all the time. Help!!
iMac (27-inch Mid 2010), OS X Yosemite (10.10.3)
