I don’t know why this just start happening but the Adobe related ‘CEPHtmlEngineHelper’ just started causing the old Mac fan and CPU usage to go crazy.
Looks like it was resolved in private build by Adobe in February 2016.
Guess I’ll update the CC 2015 apps and see what happens, eh?
Update: It appears that the latest updates resolve the problems with ‘CEPHtmlEngineHelper’…
