How To Fix App Is Damaged And Cannot Be Opened On Mac

Overview

Mac has enabled a new security mechanism that only allows the installation of apps from the App Store by default. If you want to install third-party apps, you need to change the Settings, but Mac hides this setting by default. At the same time, the files of some approved and cracked apps may be modified to cause invalid signatures and display corruption during runtime.

Usually, When an app is damaged and cannot be opened, Mac will pop up one of the following messages:

1. XXX is damaged and cannot be opened, you should move it to the Trash.
2. XXX can’t be open because it is from an unidentified developer.
3. XXX can’t be opened because Apple cannot check it for malicious software.
4. Installation failed. An error occurred while installing the selected updates.
