"Open a Finder window and navigate to wherever you've installed the Rocksmith Tools Launcher app (looks like it's in the Applications folder). Leave that window open and launch Terminal. Paste this portion of the command into Terminal: xattr -cr Make sure to include the space after "cr" then drag your Rocksmith Tools Launcher app into the Terminal window. This will autofill the directory and the name of the app, eliminating the chance of something going wrong due to spelling errors, use of spaces, etc.. When you drag the app into Terminal, it should appear as Rocksmith\ Tools\ Launcher.app Give that a go, and good luck!"
