I have a sony bluetooth keyboard + trackpoint mouse CECH-ZKB1ES. It is originally made for the PS3, but it is bluetooth and should work with anything that has bluetooth.
I've tested the keyboard with android, iOS, windows, linux, and OSX.
On previous versions of OSX (yosemite) the mouse buttons were not recognized, but the keyboard part worked.
On El Capitan the mouse part began to work as it should.
Last night I installed the last beta 10.11.2 beta (15C27e) and ever since I can't use the keyboard any more.
I've tried unpairing and pairing again, resetting pram and smc, and nothing.
I can pair the keyboard, but the moment it is paired a new icon (an empty battery I think) shows under the device name, and the keyboard switches off.
If I turn on the keyboard with it's button, it connects for a moment, the battery icon shows up, and it turns off.
Of course, I have fresh batteries on the keyboard and it works and stays on paired with other devices, like my iPhone.
