OpenGL is old and slow and not very well supported by the OSS community any more, Vulkan is newer and faster and better supported.

Please do a full **clean** re-install:

- move any valued save games elsewhere
- "uninstall" in Steam-CK3
- manually delete both the Steam/SteamApps/common/CK3 AND Documents/Paradox Interactive/CK3 folders
- re-install game in Steam, run a Steam Verify when done.
- start the game with no mods active and test

In particular make sure there are no files or folders left under either the Steam CK3 or Documents CK3 locations, before installing again.

**File Locations on Mac OS X**
The executable and DLC folder are in Users/USER/Library/Application Support/Steam/SteamApps/common/Crusader Kings III/
To see it go to the Finder, hit command-shift-G (ie Go To) and type in ~/Library/ .
The user files (settings.txt, error logs, saved games, gfx, mods) are in /Users/USER/Documents/Paradox Interactive/Crusader Kings III/ .


If that doesn't help, your issue is very likely that Intel video system, which is not - and never has been - supported hardware for this game on Macs.

You can try updating MacOS to the very latest to get a newer Intel video driver from Apple, but if that doesn't work all you can do is revert the game to the previous version 1.10.2 in the Steam betas tab for the game. Hopefully you have or can get access to supported hardware to run the game properly at some point.

Or if you have Apple Bootcamp installed, run the game under that.

Sorry for the bad news!
