Hello all, 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.
Upgrading the OS shouldn’t have effected your Bluetooth keyboard physically. It just maybe happen to fail at the same time. I would take the batteries out and check to see if one has leaked. If so you’ll need to clean up the electrolytic ASAP as it is corrosive. Follow this IFIXIT guide: Disassembling the board, power button and battery compartment of an Apple Wireless Keyboard.
I have the same problem. Left command and x c v b n m . , not working but it happened after I cleaned it, went out for a couple hours and came back and it was like this. I’ve tried cleaning and drying it out as well as configuring keyboard settings but nothing.
I have the same problem. Last week I was given a replacement keypad by Apple and it worked for 5 days with its original batteries. Yesterday, all keys stopped working except arrow keys (I can still play Pac the Man) I bought a cheap $9.90 keyboard made in China at Target the same day I brought my keypad back to Apple, as backup. That is what I am now using successfully. How odd is that? It uses 3 AAA batteries. Apple have since designed a new wireless keyboard with recharger inside instead of battery power. I think they know something about this wireless keypad less than 1 year old that I purchased with my Yosemite imac retina for a lot of money. This has something to do with blue tooth connectivity. My foreign board is all plastic, not metallic.
