I am having the same issue. I can run the CDLC and then tune my guitar, then all I see is the amps and no song. It picks up my guitar if I play, but will not run the song.
Still can’t get CDLC’s to work on my Mac. I updated, ran the path, but they still don’t work. Any suggestions. I have macOS Catalina running on my iMac. 4.2 Ghz, 16 GB with Radeon Pro 575 4 BG
I am having the same issues. Also, my mouse can’t click on anything when Rocksmith is up and running. Had several conversations and messages with Ubisoft. Not going well. Using Catalina on my iMac.
