[2021] Can't launch CKIII in Steam using Paradox Launcher after update (Mac)

If you now see launcher 2021.5.2 your issue may not be a launcher problem at all. Can you start the game from ck3.app directly?  

If this was happening on Windows it would typically be an antivirus app getting in the way, and be fixed by adding exceptions in that app and/or running as the Windows Admin user.

Pretty unlikely for those to apply here, I assume you use no AV app like most Mac users?

Given that both the game and launcher are up to date for you, I'm struggling to see why you can run ck3.app but the launcher cannot.


You can bypass the launcher by following these instructions:

- Download the attached file dowser-mac.txt
- rename it to just dowser
- move it to your Home folder (the one in Finder with the little house icon)
- run the Terminal app. That will open up a command line to that folder; do LS to check that dowser is there.
- then do this command: chmod +x dowser This is to set the file to be executable on your Mac
- then move that file to the Steam-CK3-launcher folder, to overwrite the existing file by the same name
- delete the ~/Library/Application Support/Paradox Interactive/ folder again
- Run the game

That should allow you to use DLCs and play MP. the main point is to see if the game can be started okay that way.
