The 10.10.2 update has introduced bluetooth connectivity issues.
The 10.10.2 update has messed up my bluetooth connectivity. I know this update was intended to resolve connectivity problems. However, before the update I was not experiencing any issues. Now, my bluetooth drops connectivity -- can't keep my Magic Mouse online. Please Help; is there any way to uninstall 10.10.2? Thanks.
MacBook Air, OS X Yosemite (10.10.2)
