I have this mod pack here containing ~90 mods. (for use with MultiMC)

When I attempt to play on my Mac, within minutes it crashes, with no error. It just stops after some heavy lag. However, using the same computer, with the same maximum amount of memory as on OSX, it runs flawlessly, without issue.

Why is this? Is there any way to fix it?

Hi, Eric. I am voting to close as too localized as questions are meant to be able to help the greater audience of the Internet. Since it works in Windows, but not OSX, it has to do with something inside the operating system itself that is not working correctly. It probably has something to do with your hardware as well, but I'm not 100% sure on that one. Between those two items, this is probably something that's unique to your setup. – fbueckert Jan 17 at 14:47

This question is unlikely to help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet. For help making this question more broadly applicable, see the FAQ.

Bear in mind that I know nada about Minecraft or its mods beyond that it's written in Java, but here's a guess based on past experience with something similar.

An important difference between windows on one side and most unix and unix-like OSes is that the former doesn't give a damn about capitalization -- to windows, DoSomethingOrOther.java would be the same file as dosomethingorother.java, and a call to load the latter will settle for the former.

In MacOSX or linux or *BSD, however, DoSomething.java and dosomething.java are two entirely different filenames, and if the program is ordered to call DoSomething.java while only dosomething.java exists, it will fail.

(Your trivia for today: The second expansion pack to the original Neverwinter Nights, Hordes of the Underdark, had a similar error in one of its scripts that made a certain puzzle in the late part of the game unsolvable -- the script called for a file that wasn't capitalized as it should have been, which resulted in that animation not playing and a door not opening. Good times, good times...)
