Photoshop CC, Lightroom CC & Bridge CC are giving me a VERY SLOW issue on my iMac. I thought after I cleared my hard drive (now it’s over 70% free at 705GB free space) I’d be moving quickly for each task, but it’s unacceptably slow. I see more of the spinning beach ball than I do of my work (& family!!). I have 2.93 GHz Intel Core i7; 16GB 1333MHzDDR3; with an ATI Radeon HD 5750 1024MB. Please help me understand what I can do to resolve this.
