If you are working on Mac OS X 10.9.2 or newer, you may see a message about a software installer being damaged when you try to launch it. Saying the software 'is damaged and can't be opened. You should eject the disk image' or that the software 'is damaged and can't be opened. The safest approach is to look for a later version of the app from the Mac App Store or look for an alternative app. To override your security settings and open the app anyway: In the Finder, locate the app you want to open. Don’t use Launchpad to do this. Launchpad doesn’t allow you to access the shortcut menu. Some Mac users have discovered they are unable to open some applications downloaded from the Mac App Store. When attempting to open an impacted app in OS X, a message stating “Name.app is damaged and can’t be opened. Delete Name.app and download it again from the App Store.”.

This is unarguably the easiest way to resolve the 'This copy of the Install macOS.app application is damaged, and can't be used to install macOS.' All you need to do has been broken down into the following steps: Disconnect internet before turning on your Mac, boot your Mac with Installer. Go to OS X Utilities screen, select Utilities.
- On Finder, Go > Go to folder > /var/folders
- You will see two letter folders like the below. Apart from zz, open each two letter folder and it’s subfolder until you find folders labeled with O, C, and T. Clear the contents of each of the O, C, T folders.
- Restart your Mac
