Download championship manager 2008. Since the launch of macOS Sierra in 2016, Apple has tightened up the Gatekeeper security. One very visible change thanks to this is the option to allow apps from ‘unidentified developers’ missing from settings. This tight security causes some apps downloaded from sources other than App Store to show ‘this app is damaged’ or ‘this app can’t be opened because it’s from an unidentified developer’ message.

In previous versions of Mac OS X (now simply macOS), there used to be three options under Settings > Security & Privacy > General. The “Allow apps downloaded from:” area had options, namely: App Store, App store and identified developers, and Anywhere. You could simply change this to ‘Anywhere’ and run any app on your Mac. In macOS versions since Sierra, Apple no longer provides this option in Settings by default. But there’s still a way to bypass Gatekeeper, add ‘Anywhere’ option back to Settings, and solve ‘this app is damaged’ error.
Now, ‘This App Is Damaged’ message is not really an ‘error.’ It’s a ‘security feature’ designed to keep your Mac from running unauthorised apps that can possibly contain malware.

Once you disable Gatekeeper and run app(s) you want, you should change the security settings back to normal. Leaving Gatekeeper security turned off leaves the ‘gate’ open for other unauthorized apps as well and it’s recommended that you leave Gatekeeper on.

sudo spctl --master-enable
That’s it. You’ve reverted to default security settings. After this, you will still be able to run the app(s) that previously gave you error. If you install a new app after turning on Gatekeeper, you will have to turn it off again in order to run the new app(s).
