AFTERPAD

I have a SteelSeries Stratus, which works with my iPad and the Apple TV 4, but not with my mid-2012 retina MacBook Pro.  It'll pair in the Bluetooth panel of System Preferences, but the test software I've written never receives API notifications for game controller connections from it.  To be fair, the product page for the Stratus does only claim it'll work with iOS devices.  Only the Stratus XL and Nimbus claim Mac compatibility.
