I'm trying to connect a Sony DualShock 4 controller to my iMac via Bluetooth. My iMac is a late '12 27" model. I can plug it in via USB and get it to charge (pulsing orange light). When I unplug it, I push the PS logo button and it flashes blue. I try to connect via Bluetooth to my iMac using the Bluetooth pref pane, but only once it a while it actually shows up as 'Wireless Controller' in the list. If I click 'connect', it tries and always fails. What gives? I want to use this with OpenEmu to play old SuperNintendo ROMS is all. I slaved through Final Fantasy IV (er...II....whatever) and it kinda sucked using the keyboard.
