This mod is not compatible with Mac OS. The mod adds files as if it were in Windows.

Why not? Did you have crash log?

I don't have a changelog. Just an image.

I believe I get this error because the directory is set as if I am using Windows. I am using MacOS.

Yes, I only develop on Windows. I will try to fix it if I got Mac.

If you want, I can attempt to fix. I will just need to know where to start. Such as where do I have to go to change the file directory.

Please try with dev build (1.12.2) : https://drive.google.com/file/d/1sZargDVQNRTO_BLgw9fAAjEgLaz9SB_r/view?usp=sharing

OK, This should be fixed in 1.3.4.

Please reopen this if you still got an issue, Thanks!

This is very difficult if you want to edit the mod but yeah, I appreciate your help. :)

You fixed it! Nice!
I was still learning to how to edit the mod xP
Ima still continue to learn API's so I could probably help in the future.
