Modpack Version

1.21.1

Describe the issue

I'm trying to download this modpack on my macbook air M3 and for some reason i cannot get it to work properly. I am kinda new to downloading modpacks onto my macbook so it could be user error but I was wondering if someone could point me in the right direction.

you need to install a better java build, this is a very common problem on MacOs, the standard Java install is pretty crappy. I recommend going to adoptium.net and find the latest Temurin build of Java. Shouldn't be too difficult, good luck.
