Hi, I reformatted my MBP a few days ago (yes, I'm crazy), and now when I decided to install Photoshop CS5 Extended, it did not bring the option of a 64-bit version, meaning my MBP is now running only on 32-bit mode. But I remember that when I installed it before, it did. So obviously I was running 64-bit mode. Did yours come by default with 64-bit mode? Should I go ahead and change it back to 64-bit mode?
