I've been using a LMP model WKP-1314 keypad (bought at the Apple store) with all the versions of OS-X through 10.10.3, but after upgrading to OS-X 10.10.4, the Mac Pro no longer recognizes the keypad via Bluetooth. I've tried new batteries but nothing get the connection between the Mac Pro and the keypad now. Has anyone else had problems with third-party equipment which was working but doesn't now with OS-X 10.10.4?

If your Wi-Fi is capable of generating a 5 GHz signal, try that.
Didn't help. Nothing changed. The LMP keypad worked through 10.10.3, but after updating to 10.10.4, it doesn't connect anymore.
Finally got it to pair with the Mac Pro. It took several tries (batteries, on/off and reset button) to pair and enter the number the Mac displayed. Weird, but working again.
I just got mine to work again. I shut it off and turned it back on again, then re-paired it to the Mac. This involved pushing a little button on the back (which started a green light on the front flashing), clicking the "pair" button in the Bluetooth System Preferences panel, and entering the displayed six digit code on the key pad. I'm glad it's back! (Using OS version 10.11.6 El Capitan.)
