I couldn't get this to run on my MacBook. I'm not sure if it's my graphics card or the mod itself that's making it crash. It tries to load up the game but I keep getting the same message. Which is weird because I've ran over 150 mods through CurseForge on this laptop with no issues, I tried loading the mod without my shaders too and got the same result:

The game crashed: initializing game
Error: java. lang. IllegalStateException: GLFW error before init: [0x10008]Cocoa: Failed to find service port for display

Anyway around this?

Thanks

Here's the crash report

That to me seems like a system level Java crash. Atum is not mentioned in the crash report either.

Try running the pack but without Atum.
