Why is my Mac saying my files are damaged?
The first thing you should do to try and remedy the “app damaged” error message is to re-download the app to the Mac, and make sure it comes from a trusted source. Often simply re-downloading the app, trashing the ‘damaged’ version, then relaunching the freshly downloaded copy will resolve this error message.
