    Why does photoshop use 12% CPU when idle and no documents are open? (OS X 10.9.4, PS CC2014.1)


      Or, more generally, why do CC products eat up CPU when idle?


      Photoshop: 12% when idle, no documents open.

      Dreamweaver: 3% when idle, no documents open. Easily 50% when editing *text*.

      Creative Cloud: 14% when idle, no updates pending, etc.


      In terms of CPU, the only processes that cumulatively eat more CPU are the kernel_task (OS) and WindowServer. Photoshop -- running totally idle for a few days -- eats more CPU time than all my frenetic Firefox, Mail, Finder, Chrome, Safari, etc. work *combined*.
