Yes, the update messed it up. I do not know what is wrong, but I think Open Gl has a problem. I tried safe mode in the Falador party room with 1000+ people in it, and it didn't crash. I only played for 15 min there, so I don't know if safe mode will work. Hopefully Apple will fix it soon. This update has "so" many bugs. Also, its kind of weird. It sometimes makes some of my icons on my desktop dock black with white spots on it. Though this does not make my computer crash. I wonder how a browser game can affect your desktop...
