your RS patch is not on the default location. search on your system where is located the steamapps folder. then go to common/Rocksmith2014/. copy the full path and then edit the RUN_PATCH_RS.command with textedit. Replace the line "RS_PATH="/Users/$USER/Library/Application Support/Steam/steamapps/common/Rocksmith2014/Rocksmith2014.app/Contents/MacOS" with your correct path. you should change the first part of the path. Then run the RUN_PATCH_RS.command again. should work. First of all, thanks for coming up with a solution, however, I don't really understand this kind of stuff, so if someone would be able to help, I'd appreciate it. I have my Rocksmith on an external hard drive and I think the path is Seagate Replica>MAC>Steam Library>SteamApps>common>Rocksmith2014. How do I copy the path then edit the command in text edit? Sorry, this is like a foreign language to me lol. Again, thanks for the help! Go to applications, open TextEdit application. then open the RUN_PATCH_RS.command file with TextEdit. TextEdit is like the windows notepad, just a text editor. replace /Users/$USER/Library/Application Support/Steam/ to \Volumes\Seagate\ Replica\MAC\Steam\ Library\ Save it. then you need to change permissions. like other posts, open a terminal, go to the patch where RUN_PATCH_RS.command is located. run: chmod 755 RUN_PATCH_RS.command chmod 755 insert_dylib ./RUN_PATCH_RS.command next, open steam and launch RS from steam app. I still can't seem to get it to work. I changed it in text edit to what you said (Copy and pasted) then changed the permissions. I first did cd DOWNLOADS/MAC_Patch which you told someone to type in a previous post, then I copy and pasted chmod 755 RUN_PATCH_RS.command chmod 755 insert_dylib ./RUN_PATCH_RS.command So, I'm not sure what I'm doing wrong lol. Anyway, thanks for being patient with me and trying to help out. I really appreciate it!
