Re: origin won't open on mac TRIED EVERYTHING
@clairelzabeth, So it sounds like you can open Origin, but then it crashes? Can you start it and then immediately go into the Preferences? It sounds like you need to disable Origin In Game because it can cause Origin to crash when on the new Mojave Mac OS. If you can't get to the Preferences, try this workaround to allow you to start Origin so you can disable the Origin In Game feature and download the game.
