The recent firmware 1.1 update appeared to install correctly. BUT, since the update the keyboard does not work properly - random ’ characters and shift key not shifting case. Attempts to reinstall 1.1 update or 1.0 updates are blocked by - “Your keyboard is already updated!” Any secret key combo to reset the firmware or force a new (or old) update? Or do I now have a useless keyboard? Mac Mini. OS X 10.6.3 aluminum bluetooth keyboard (2007 3 battery)

Here is the Apple paperwork for the update giving you problems. It appears to list steps to be taken after install. Maybe this will help you. Ralph http://support.apple.com/kb/HT4010

This works… resetting BT keyboard Basically, you need to hold the power button the ENTIRE time you pair. Try and see if it works.

The A1016 Mac wireless BT keyboard WILL work with Mavricks with no additional software, I dug out my old keyboard and put new batteries in and it attempted to paired up, but I had to remove all the other devices and then pair. After that you can pair up your other devices. I had to have patience, but it got there
