@Milo6485 Odd, that version works for me. I got the same error message you got only if I try to run the application from inside the disk image. Give this one a try and let me know if you get it working. It is a new Rocksmith Tools for Mac AIO that was just released which includes the latest version of all tools.
@cozy1 Your new file works perfectly!!! Thank you very much, it's a very good idea to have all the app in one Thanks again.
