Installed DD through GOG and running macOS 10.15.3. Game doesn't launch, all I get is the icon appearing in the doc for a second and then disappearing. I haven't found any other info about this anywhere else– is this a 64 bit compatibility problem or a me problem or something else?

Any chance you guys adopt all the divinity games for new x64 OS?

I was having the same issue on Big Sur and found I could get it run by:

- right-clicking the app and selecting "Show Package Contents".
- Navigate to "Contents/MacOS/"
- Double click "Divinity - Original Sin"

Maybe the same on Catalina?

If you're curious if it's the same issue, in the Console these are the errors I see on crash:
