Yosemite magic Mouse and a bluetooth disconnection party I hope some real OSX Nerds read this. Since Yosemite I have the problem taht I can't use the Magic Mouse anymore. It disconnects and reconnects every 5-60 second. 

I find this in the console logs:

05.11.14 14:39:22,000 kernel[0]: [AppleMultitouchDevice::willTerminate] entered
05.11.14 14:39:22,000 kernel[0]: [AppleMultitouchDevice::stop] entered
05.11.14 14:39:35,000 kernel[0]: [BNBMouseDevice::init][85.3] init is complete
05.11.14 14:39:35,000 kernel[0]: [BNBMouseDevice::handleStart][85.3] returning 1
05.11.14 14:39:35,000 kernel[0]: [AppleMultitouchHIDEventDriver::start] entered
05.11.14 14:39:35,000 kernel[0]: [AppleMultitouchDevice::start] entered


Can somebody hint me in the right direction, how to solve that problem? Please.

it's so anoying

Update!  - Delete "Bluetooth PAN" from network settings and wifi and bluetooth will  instantly work better.  Credit: http://ihealthgeek.com/2015/02/yosemite-10-10-2-wifi-and-bluetooth-finally-solved-no-really/


Otherwise, you can try my previous approach that works better, but is still a nuisance.




Turn off bluetooth on macbook
turn off keyboard/mouse
turn on bluetooth on macbook
Hold power-on key on keyboard WHILE
Choose the Bluetooth>Device>Connect from the macbook
Connection should succeed immediately
Release power button on device


This has worked for me repeatedly after trying the PRAM and other no-fix fixes.   It's a pain to do, but works everytime for me, and stays connected until I leave the room.
