The U2715H was not tested/validated by Dell with the Apple proprietary hardware and software.

* Turn the U2715H off
* Disconnect every cable from the U2715H including the power cable
* Press and hold in the U2715H power button for 10 seconds
* Reconnect only the power cable to the U2715H
* Turn the U2715H on
* The floating dialog box should appear on-screen (against a black background). Then, run the BID (Built-in Diagnostics) page 55
