The first thing you should do to try to fix the "app damaged" error message is to download the app to the Mac and make sure it comes from a trusted source.

For example, if you download Google Chrome or Signal, make sure you download these apps only from the developer site, do not download them from third-party websites.

Sometimes, the download method does not work, and sometimes downloading an app directly from a developer or trusted source is not an option, and sometimes you need to download certain apps from third-party sites (especially with old programs that have become abandonware ). In these situations, try the next approach to getting around "the app is damaged and cannot be opened".

You can restart your Mac by going to the Apple menu and selecting "Start" again.

When your Mac has booted, try opening the app again.

3: Install Available System Software Updates

It appears that sometimes this error message appears due to specific system versions and / or gatekeeper. Installing available system software updates on Mac can often solve this if that is the case. Be sure to back up your Mac before you do it.

For MacOS 10.14 or later (Mojave and later): Go to the "Software Update" preferences pane of System Preferences to find available updates for MacOS system software.

For MacOS 10.13 and earlier: Go to the Mac App Store's "Updates" tab to find available system software updates.

For Pre-App Store Macs (10.6 and earlier): Use the "Software Update" preferences pane in System Preferences as well. 19659008] If system software updates or security updates are available, install them for Mac.

Note this does not suggest updating large OS releases, which is a much more complicated task, just to update available system software updates. For example, if your Mac is running El Capitan 10.11.x than install any El Capitan-related updates available.

4: Use xattr on the App that throws the damaged error

This is a last resort and is only recommended for advanced Mac users. Usually if the app still throws a "damaged" error message, you may not use it. Use this at your own risk.

With the command line, you can use xattr to view and remove extended attributes from a file on Mac, including the application that throws "Appname.app is corrupted and cannot be opened. You must move it to the trash." Error message.

Launch Terminal and then issue the following command:

xattr -cr /path/to/application.app

For example:

xattr -cr / Applications / Signal .app

-c flag removes all attributes, while -r applies recursively to entire targeted .app directory contents.

The command xattr can also be used to clear the error message "The program downloaded from the Internet" on Mac as well. Again, this is only recommended for advanced users because changing extended attributes may have unintended consequences, and again, try running an app that you should not run, either for stability, privacy, security or other reasons.
