Open an app by overriding security settings
Overriding security settings to open an app is the most common way that a Mac gets infected with malware. You should not override security settings if an app hasn’t been checked by Apple, even if the app looks like it comes from a major developer.
However, if you choose, you can still open an app that isn’t allowed to open by manually overriding Privacy & Security settings.
On your Mac, choose Apple menu
in the sidebar. (You may need to scroll down.)Go to Security, then click Open.
Click Open Anyway.
This button is available for about an hour after you try to open the app.
Enter your login password, then click OK.
The app is saved as an exception to your security settings and you can open it in the future by double-clicking it, just as you can for any authorised app.
