Dalmanours:

I guess You've tried to connect via blutooth. For this time it's impossible to do that. You can only connect your device via USB.

There's a new version of H9 Control out that has support for Bluetooth on Mac OS X and Windows.  You can now connect to your H9 over Bluetooth on your Mac by going to the Devices menu in the Mac menu bar and selecting "Connect via Bluetooth".
