...it works with any OS X version as long as you're running iTunes 11.2.2
Should the "stoplights" look flat like Yosemite on any OS?
Interesting, I was not aware of that. Thank you.
There are multiple traffic light files (12 or 15) and I only modified 3 of them (1 red, 1 yellow, and 1 green). I don't think it matters which OS you're running, it's probably the screen resolution. Im not positive about that tho.
I'll add the rest as soon as I have time. Check back in the next day or two.
