White/Gray Screen

[DonyorM]

Here is my problem: whenever I tried to launch any modpack, it always gets stuck on the download.

So I got around this problem by having a friend send me the files from his computer, that gets past the downloading problem, but whenever I launch voltz (for that is what I'm launching), it fails to work. Instead it just opens a white/gray screen with voltz on the top.

I'm on a mac.

This sounds like a Voltz modpack bug. In that case, go HERE.

Please test the other modpacks so we can learn whether or not it's a modpack or pc problem. Antivirus is usually the bad guy here...

I can't test any other modpacks because downloading them won't work. I'll try though.
