Hey peeps, Would it be possible to use a Bluetooth 4.0 USB adapter with my Mac? I have an early 2011 MacBook Pro that only has Bluetooth 2.1 EDR. The requirement for the new Magic Trackpad is Bluetooth 4.0. Is this a possible workaround? USB 2.0 has more bandwidth than BT 4.0 can use so no data bottlenecks. I'm also running 10.11.
