As the title says, I am playing on the Mindcrack pack using multimc with Optifine and my game is crashing after 5-10 minutes of playing. Here is my crash report - http://paste.ubuntu.com/5614592/ - I am on a mac and my specs are Processor 2.9 GHz Intel Core i7 Memory 8 GB 1600 MHz DDR3 Graphics Intel HD Graphics 4000 512 MB. I would like to know why my game is crashing and how I can fix it.
