I am using the trial version of RB, on my Mac Mini (Mac OS 10.9) and so far it's been working great. My Harmony One is the older one released in 2008 - predating the Touch and Ultimate.
This one: http://support.logitech.com/en_us/product/harmony-one-advanced-universal-remote
My Harmony One is programmed as an Apple TV remote (seven buttons for U/D/L/R/Select/Menu/Play). With RB this can wake my Mini, launch Plex and control it.
However I want to use the additional buttons on the Harmony One - such as stop/FF/RW etc in Plex, and bind extra functions such as change language/subtitles etc. to touchscreen buttons.
Is there a simple way to use this remote with more than 7 buttons, and yet work seamlessly with Mac OS? I know there are options to masquerade as multiple apple remotes but this seems very complex, and I wouldn't know how to program RB and pair these extra emulated remotes to the Mac Mini.
Thanks
