As the title says, my iMac is having lagging issues in Photoshop CS6. It takes almost 5 minutes to render one layer (even text layers take this long). My iMac 2012 model has 8GB RAM, 1TB HDD, 675MX, and my RAM shows free 33.6MB, inactive 3.33GB, wired 1.28GB, Active 3.35GB, and used 7.96GB. It there not enough RAM? My MBP has 8GB RAM and its a late 2011 model and I've never had issues, same goes for my PC. This is strange. I mean my iMac isn't lagging in Safari, or my mail. Hmm....need some help please! Thank you!
