WebStore, Open an app from an unidentified developer on Mac

Instructions to open an unidentified app on a Mac.

Sometimes it may be necessary to open an app on a Mac that is not from a registered developer. This process can be different from Mac OS to Mac OS.

If you try to open an app that is not registered with Apple by an identified developer, you get a warning dialog. This doesn’t necessarily mean that something’s wrong with the app. For example, some apps were written before developer ID registration began. However, the app has not been reviewed, and macOS can’t check whether the app has been modified or broken since it was released.

A common way to distribute malware is to take an innocent app and insert harmful code into it, and then redistribute the infected app.

If you are confident in the source of the software see below. If you are at all unsure about the source of the software, contact a knowledgeable IT Professional for assistance.

To override your security settings and open the app anyway:
    1. 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.
    2. Control-click, the app icon, then choose Open from the shortcut menu.
    3. Click Open.
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 any registered app.


 1. Open System Preferences
 2. Navigate to the Security and Privacy menu
 3. Under the General tab, select "Open Anyway."
 4. When prompted, enter the password for a computer admin
