Over the past couple of days, some users may have noticed a problem with the Mac App Store – they say that the downloaded application is damaged and must be downloaded again from the Apple software store. As many developers have noticed, this is the fault of the Cupertino company itself, which did not renew the Mac App Store certificate. Fortunately, this problem was also solved. And no, not reinstalling the “damaged” applications.

Fix Mac Application Can’t Be Opened

There are several different tips and tricks that can fix these “damaged applications” error messages on a Mac.

Reinstall App

The first thing you should do to try to fix the “the Application can’t be opened, you should move it to the trash” error message is to re-download the application on Mac and make sure that it is received from a reliable source.

The second of the easiest solutions is to restart your Mac. It helps in about 80% of cases, and it is possible that you will be among the lucky ones. If the error still persists, you need to start the Mac App Store after a reboot, sign out of your account, and then sign back in.

Use Terminal

Using the command line, you can use xattr to view and remove extended attributes from a file on a Mac, including the application that displays “Appname.app is corrupt and cannot be opened. You must move it to the Trash.”

Run terminal, and then execute the following command:

xattr -cr /Path/to/Application.app

Conclusion

One of these methods should save you from having to reinstall applications that do not start due to an Apple error. It is amazing, of course, how such a large company forgot to renew the certificate.
