Mac compatible bluetooth dongle?
I have a 2010 15" MBP operating clamshell into an external NEC display. My BT Magic Mouse lags in the external display in clamshell mode but runs fine with the MBP open. After searching it appears the solution is to use a BT dongle but I can't find one that is supported for OSX. Any suggestions?
MacBook Pro with Retina display, OS X Yosemite (10.10.3)
