I've been through the steps multiple times on my Mac (10.9.2). I'm able to see the 7 or 8 CDLCs in my song list, and when I highlight one it plays the audio preview, so seemingly all is well; but the game crashes when attempting to play any of them. The one thing that I believe is the problem: when I launch RSInjector (no matter what folder location I place it in), with Steam open and the game selected, the game does not launch. I can see RSInjector in my Activity Monitor, but I have to launch Rocksmtih2014 manually. I tried re-downloading it. Does the fact that CDLC shows up in the song list indicate that RSInjector is working properly? My Steam library is located on a separate drive from my MacOS system files -- does the game have to be in the default install location (i.e. under ~/Library/ etc.) in order for RSInjector to work? Or do I have the misfortune of having downloaded only non-working Mac packages of the songs? I'm on the verge of either giving up completely or downloading the Windows version of the game. Neither appeals to me. I've just wasted too much time with this. In other news, the Toolkit seems to run just fine using Mono. The UI told me the 3 or 4 PC to Mac conversions worked successfully but I can't play them in the game. Thank you for any ideas.
