Bluetooth performance worse after Yosemite update I have a bluetooth trackpad and a pair of bluetooth headphones and ever since I upgraded  to Yosemite I've been having problems with both.

The trackpad fails to re-connect after the laptop wakes up more often that it before as do the headphones, on top of that the headphones are a lot choppier, to the point I can't listen. When connected to my phone they work flawlessly.

I'd unpaired &amp; re-paired both devices &amp; also removed them by deleting them from the .plist file directly, this improved things for a few days, but now it's back to the same problem.
This looks like a bug in Yosemite. I have this issue and other people have it also.

I think we can just wait until it is fixed or return to Mavericks. I have tried resetting SMC and some other "fixes" from the internet without success.

OS 10.10.1 Yosemite has Bluetooth Audio Delay (lag, latency)
