Before update, I have just downloaded a trial version of Star Craft II for playing. It was playing well until somehow my iMac lost its network connection from my home wifi router. Because StarCraft seems to need network connection, then the whole SC hang forever and I can't close it. So I am forced to power off the iMac and restart. After restart it is playable again. Then I turn off computer, after a while then I turn on, and proceed the software upgrade of my iMac. After reboot, it is crashing. Chrome, Flash, Star Craft,...I dont know what else is crashing. Safari and Firefox seem working.
Thanks for helping
