macOS CK3 Crash on Init

[TrotskyExile]

Hi,

I suspect I ran into some graphics API bug; the game crashes on init on my M1 Mac using Vulkan. It reaches the main menu with OpenGL, but it's super broken (no 3D rendering works, and the UI layout is broken). It doesn't matter whether it's fullscreen or not. I have uninstalled, verified, and reinstalled several times. It used to work before. I uninstalled the game a long time ago and have only started trying to play recently. No mods.

Thanks for the help in advance.

OpenGL is not supported under MacOS or Linux any more, so it is no surprise you have that problem there.

One problem though is the game's minimum requirements under MacOS include

• Memory: 12 GB RAM

and there is only 8gb here. You could try unloading every other app you can.

This doesn't make sense because

1. OpenGL makes it to the menu, so it's not memory-related unless the game only allocates this large block if Vulkan is selected.
2. Darwin has memory overcommit so the game couldn't detect an OOM eagerly if it wanted to and open the crash reporter. If the game did cause an OOM, the OS would suspend the processes and open a window titled "Your system has run out of application memory," allowing you to force-quit some processes.
3. The system relies on swapping to disk. It has used upwards of 45 gigabytes, so it's not an issue.

I see. Well, there is no known game bug like this, and I don't see anything else wrong in the game files you sent in.

We can try a full **clean** re-install:

- move any valued save games elsewhere
- "uninstall" in Steam-CK3
- manually delete both the Steam/SteamApps/common/Crusader Kings 3 AND Documents/Paradox Interactive/Crusader Kings III/ 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, I don't know what is causing this for you, if it is not the memory!
