I am a MAC user and recently went to the Apple Store and had my computer cleaned because I thought perhaps the computer was running slow. Secondly, I had my internet provider to send a technician to make sure that the internet is not slow. All good on those fronts. Which leads me to believe it's the software.
I am having issues with saving files - long delays (minutes); resulting in having to Force Quit.
Also, there's some jumpiness and slight hesitation when selecting an object, layer or mode of operation - when executed, it performs something that I didn't want or intended to do.
Moving very slow - not performing operations in real-time. (example: when using the gradient tool - color points selected - No color change.)
