How to Set Up Bluetooth in Linux

Bluetooth—so simple and yet so troublesome. For a subsection of users, Yosemite is causing problems with Bluetooth accessories and connectivity. One solution proffered by iDigitalTimes is to disconnect all USB preferences, shut the Mac off for several minutes and then try again from the beginning.

When you hear the startup sound for the second time, you can let go.
