I updated Ram from 8 to 16 gigs and found little if any difference, 70% available Ram allotted for CS6 and it still gets hung up. Anyone found a fix for this problem? I write to an external hard drive via Thunderbolt port to firewire. CS3 ran better. I never had this kind of problem. Thanks for taking the time to follow up!
