Shared By ChingLiu BE HAPPY ! * If the screen gets stuck at install open the .dmg file and drag your .app file to the applications folder. ** If you are facing the following issue : file or disc damaged (when you launch the .app, after having the .dmg opened correctly) just open Terminal.app paste this : sudo xattr -d -r com.apple.quarantine /Applications/Logic Pro X.app then it might require your personal password for your mac and then it will run correctly (you only need to have Logic Pro X.app in your Application Folder) - Just drag the LPX.app into the app folder. - Open the package (right click) > Contents > MacOS > Open the logic Pro X file into the terminal. - The install window will open, ask for a password, then will start to install.[ChingLiu] January 10, 2014Thanks to original cracker.
