Oh, thanks for the reply @@firekorn, that's great to hear! What's no so good, is that I've followed the steps and troubleshoots to the 'T' and can't seem to have the CDLC show in my game. Currently running Mac OSX Yosemite 10.12.2 with the latest version of both Steam and Rocksmith 2014 - remastered (installed in default locations), ran the patch successfully, installed version 4.0.4 of Mono successfully, can use the custom version of the RSToolkit that was posted, purchased the "Cherub Rock" DLC, and have placed GNR - "Welcome to the Jungle" CDLC in my default DLC folder of my game. After starting RS through Steam, I go to the "learn a song" tab of my already created profile and cannot find my CDLC anywhere, I can, and have, played the Cherub Rock DLC, however. Any thoughts or suggestions?
