Hi , I am having the same experience with 10.15.7 Running on a MacBook Pro 16 I have dowloaded a legal copy via steam dropped the patch into folder /Library/Application Support/steam/steamapps/common/rocksmith2014 run the UN_PATCH_RS.command (all three files changed to read and write) In system preferences I granted the patch to run in security & privacy and the other two that try and run as well when loading the custom songs they seem to be all good and even preview in the menu but on playing I get the same as what others are saying the two amps and nothing else pops up - then in the end just closes the program. Have removed twice are tried but no joy. Anyone having any other luck to get working? Seem to have tried everything in this thread with no joy, wonder what I am missing? I did run on boot camp to windows 10 - that was even worse, the sounds was just a high pitched mess when loading in! Thanks in advanced
