I'm sure there's a very easy way for me to work around this... help?

Hi! So this still just a simple fix:

1. In the Finder  on your Mac, locate the app

   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
