I have a Mac Book Pro that I'm running Mountain Lion on. I just bought my M13 a few weeks ago, but it only has firmware version 1.02 on it... I want to update it to the most recent firmware which I think is 2.04. I downloaded SysEx Librarian. I have tried everything to update the firmware but it won't help. The MIDI to USB connector is a Hosa Technology USM-422. The USB is plugged into my computer and the MIDI ins and outs are plugged into my M13 correctly. Everytime I hit play in SysEx, the M13 just says "waiting command..." in Flash Update Mode.

I have no idea what I'm doing wrong.

Any help would be appreciated!

Thanks in advance,

Nick
