Trying to figure out why my wife's iMac is running so slow. My iMac is 3 years older and runs smoothly with no problems. Hers is a "mid 2011" model 2.7 GHz Intel Core i5 with 4 GB memory 1333 MHz DDR3. Running the latest Mac software and have installed all updates. Has 923 GB space remaining of 1000. I tried googling for answers and deleted a few applications and stopped all programs from opening at launch, but nothing has seemed to help. Only thing I can think of is that she has the Adobe programs on her iMac (Photoshop, Illustrator, Indesign, etc.). Any advice? Any luck with the Clean My Mac programs? Thanks
