I'm providing this post for those problem solvers in here who might benefit from my summary, as I've just finished reading up on here too. I'm having the same issue as most on the Mac right now; cdlc will tune and load venue, but no strings appear and the program becomes unresponsive. Also of note, when loading the venue, no strings show and the lights will dim and then flicker to a stable level, and which point it's unresponsive except for cursor movements. I've had this issue for a while now, more than just 3 weeks. So far, I've been able to make some basic deductions, but programming isn't a strength of mine. Running the RS patch ends up leaving 6 files missing when you verify game files. I manually dropped the file into the Rocksmith package and then verified and had 7 missing, but I'm retesting that (I might have removed a dlc file in the process of isolating variables). I've uninstalled and reinstalled several times, rerunning the process, to no avail. I've also verified that it's not the actual m.psarc cdlc files, having converted fresh; unless maybe it's an ID# issue? The rest of the application runs normally, including official dlc. I've seen that some posts on here have found success through strange things, like skipping the tuning screen; that seems like an aberration, though, with only one person having mentioned it. Personally, I've been skipping that step every time trying to resolve this, and I've never had success. After running the patch, I'll get a "problem" message allowing to ignore or report. If I drop the file into the package without running that shell, I don't get that message. This is all I have to contribute to the effort so far, but I'll mention more if I happen across a good solution as I continue to work on this.
