HelP with MIDI please

Hello

I have tried to follow the below instructions to connect my Yamaha YDP 140 to my mac pro:


To verify the installation of the Yamaha USB MIDI Driver on Mac OSX, follow the steps below:
1) After installing the Yamaha USB MIDI Driver and restarting your computer, access the Apple System Preferences menu.
2) In the Apple System Preferences Menu, select the "Yamaha USB-MIDI" icon located under the “Other” category. This will confirm that the driver has been installed.

*
3) To confirm connectivity between the MIDI device and the computer, view the "Device Name" drop down. The instrument or device model will be listed (example: Yamaha Motif-R XS).
*

4) Select "Send All Note On" to verify MIDI note transmission between the computer and your device. When selected, a note should sound on your instrument.
Note: If using a UX16 USB MIDI interface, ensure that that MIDI ends are properly connected to the instrument in the following fashion: IN>OUT and OUT>IN


I have managed to get to stage 3 but there are no drop downs in the menu and I can't select anything in that window!

Any help would be much appreciated! I am using a MIDI to USB cable and the cable is lighting up and does work... Also my USB ports are all working...

Please help... I'm clueless!

That's strange on the couple of MIDI devices I've used its just plug and play. Is the Yamaha not standard MIDI?

Plug them in, Open GarageBand, ensure the Track you're playing on is Green for MIDI and Rock it.
