Just installed Mavericks on my late 2012 iMac. Seemed fine at first but within minutes my keyboard started acting up. I can get it connected by pressing the keyboard button and the battery power is showing 100% but it can't be detected under the keyboard utilities - or it detects it very briefly and then loses it again. Have restarted, changed batteries etc. but the problem persists.
Decided to revert to ML - thought I'd back up my photo library first - now the iMac is password locked and of course I can't enter my password to unlock it!
Strangely enough, some keyboard buttons work - like volume, brightness and (bizzarely) the 'o' button....
Bluetooth mouse working fine. I may need to buy a wired keyboard just to get a working iMac again!
