I bring my laptop (MacBook Pro) home from work, where it works fine, and it crashes. That is weird as I also have an iMac running the same exact things with MC and no crashes!

 

I'm running forge 1.7.2 and MC 1.7.2.

 

Here is the crash log:

Any help would be appreciated.

Post the actual log file from the logs folder.

One or more of your mods is doing something to cause Minecraft to crash, in such a way that doesnt let the crash report be created.

{Note: This is nothing to do with Forge itself}
