[CRASH] Mac version keeps crashing with Bugsplat errors. Started only recently.

This only started recently, I'm assuming because of the most recent patch. The Mac version of the game is crashing ~1-3 times a game with a Bugsplat error, but there is no info given in the description fields of the error.

How to reproduce:

1. Download LoL for Mac
2. Play a game, wait a while. Seems to happen completely randomly. Not triggered by specific skills, and it happens regardless of how intense the action is on screen. It happens to me sometimes while I'm just walking to lane with no minions/teammates nearby, but it has also happened during teamfights.

This was NOT an issue before either this last past or at most the patch before that. I have played LoL on a Mac for almost a year without issues.
