    This periodic problem of a disconnecting keyboard still plagues my work colleague and I. We have wired extended keyboards (which have been replaced to discount a faulty keyboard). It invariably happens after a restart or power outage. There is something clearly iffy about the power management of this keyboard. Successful ways to bring it back to life include plugging it into a usb extension cable, and another is restarting with the keyboard cable unplugged then when the mac is fully booted plug the usb cable back in. We are using 21.5 inch iMacs (late 2012) running 10.8.5.

    I had frequent disconnects followed by reconnects on a brand new Apple wireless keyboard. As it turns out, the problem was not with Bluetooth at all but with the batteries being too “loose” causing intermittent loss of power due to the vibration of typing. I tried shaking the keyboard in different orientations and sure enough I could induce the disconnect most of the time. I had not suspected that it had anything to do with the batteries because they were the batteries that the keyboard shipped with and were still at 100% charge. My solution was to place a small flat metal washer between the battery negative terminal and the battery compartment door. This extra snugness made the problem go away instantly. So try the shake experiment if you haven’t already. I am wondering if I should return this keyboard as defective though because the batteries should not be that loose.
