[1.7.10] game crashes when trying to play single player

[916253]

Me and a couple friends put together a modpack we've been playing on for a while, and they are both able to make and play in single player worlds just fine, but whenever I try to load a world, it crashes.

here's my crash log:

here's a list of my mods:

Another note: both of them have windows, I have a mac.

Any help would be appreciated!

One of your mods is incorrectly using global Entity IDs. Sadly due to the way these works it is impossible to tell which mod it is, so you have to take them out one by one to find the culprit.

Any idea why it would affect me but not my friends?

Which version of Java are you using?
