Might not be a mac thing.
There is a major issue with this display and the USB connections.
It is therefore hit and miss if the data connection has been made.
One thing to investigate is that if you connect display over thunderbolt does it lock the other thunderbolt port to display only, shutting down it's data connection.
So I would advise evankultang to keep trying different connections.
So try connecting the display via hdmi/displayport and only connecting data via standard usb3 port, not the usb3 port.
I may have got this wrong but I would be trying to verify that data communication is happening.
