MacBook Air 11-inch, Mid 2013 won't boot with external USB keyboard
Hello,
Just bought a MacBook Air 11-inch, Mid 2013 (8GB, i7, 512GB SSD) today.
All available software updates are installed (OS X 10.8.4 (12E3067)).
Also have a Macbook Pro Retina.
If I connect a external USB keyboard (Kinesis Advantage Pro USB) to the Air then it don't boots.
If the keyboard is connected directly to the Air USB port then it don't shows the Apple logo on grey background after power on, just give a endless loop of the turning on sound.
If the keyboard is connected to the Thunderbolt display then same empthy grey screen after power on and no sound at all.
The same keyboard and Thunderbolt display work well with my Macbook Pro Retina and a Macbook Air 2011.
Any ideas ?
Thanks,
Karsten
