I've once again tried running the Live DVD, well, Live USB actually on my iMac. Like version 12.04 my wireless Apple Keyboard (bluetooth) won't lock on for any prolonged period of time. It connects, immediately disconnects again to moment I press a key. This a cycle which continues. I've tried it with my neigbours wireless Apple Keyboard (slightly older model than mine) and the same thing happens. The really odd part is my Magic Trackpad connects immediately and is ready for use. Same goes for my Magic Mouse I pulled out of mothballs. So obviously bluetooth is working just fine, just not in combination with my keyboard.
Does anyone have any thoughts what could be causing this? Maybe a setting I can try?
(A magic Terminal command perhaps?
