Hi, I just unboxed my new Xkey Air 37 and updated the firmware — it’s beautiful, by the way. I followed the instructions for connecting the keyboard to my iMac using the Audio MIDI Setup app. When I double-click the big Bluetooth icon, I get the following message:

“MIDI over Bluetooth is not supported
This Mac does not support Bluetooth LE.”

I don’t see anything in your specs or product documentation specifying hardware requirements. I own an iMac from 2010 running the latest version of Yosemite. Did I just miss the information somewhere or is there a particular minimum model of computer I need to have to use this wirelessly?
