Unable to run compiled mod on MACOS

[OssieFromDK]

Hi, I have been working on a mod with this template, it works great for Windows, but when I try to load the mod with Forge 1.8.9 for MACOS, it get the following error:

[Client thread/WARN] [FML]: Zip file super-duper-fishstick-2.0.3.jar failed to read properly, it will be ignored

Full error log: here

My mod is called super-duper-fishstick

Thanks

I have also tried compiling the mod from my MACOS machine to check if there were some changes, but its the exact same.

Are you sure you are compiling the remapJar

Are you sure you are compiling the remapJar

I don't think so, how would I do that?

[OssieFromDK]

I tried running the remapJar gradle command but it didn't change anything sadly, both being compiled from Mac with IntelliJ or from my Windows machine.

Got the exact same error
