White Screen Once I Login

[iiSNIPEinHD]

Launcher Version: Tekkit 3.1

Operating System: Max OSX Mountain Lion

Java Version: Java 7.0

Antivirus Program:

Description of Problem:

When I hit the login button it will startup as normal but when it goes to the Mojang screen it's just white and Tekkit completely just shuts down.

I've already tried re-downloading Java, and Tekkit Launcher but none of the two have done me any good.

Downgrade your Java to version 6 (from Apple).

That didn't make a difference. The white screen is still appearing.
