In the exit conformation window, did you try just hitting Enter?

If you create a new profile and start a new game, do you have the same problem?


Try verifying local files:
In the Steam library, right click on the game and select Properties, switch to the Local Files tab and then click on the 'Verify Integrity of Game Cache...' button.

With the GOG version, in the (optional) Galaxy client, select Divinity: Original Sin 2 in the left column, then click on the More button, and in the Manage menu select 'Verify / Repair'.

With the App Store version, or GOG without using Galaxy:

Terminal
bash-3.2$ cd ~/Library/Application\ Support\ ... up to the Divinity Original Sin 2.app folder
bash-3.2$ codesign -vvv Divinity\ -\ Original\ Sin\ 2.app

This takes a while, and will output some lines starting with '--prepared' or '--validated'. If everything is fine, it will end with:

Divinity - Original Sin 2.app: valid on disk
Divinity - Original Sin 2.app: satisfies its Designated Requirement
