Forge won't go past "Opening Main Window" on my MACos.

Before anyone says that I should get the Mac version, I tried and I couldn't figure it out.

Secondly, I just got the windows version and in the end, it worked until about a month ago and I've been trying to fix it ever since. Any time that I open the .jar it gets stuck on the "Opening Main Window" message on the loading bar and I don't know how to get past this on my Macbook.
