On my MacBook Pro Retina, I have Creative Cloud installed. When I try to wake up my computer from sleep, it has about 15 seconds where it shows a black screen, and then 15 seconds later shows the login window. This does not happen when Creative Cloud is not running.
The system log says:
9/10/15 6:19:33.000 PM kernel[0]: PM notification timeout (pid 94993, Creative Cloud)
9/10/15 6:19:33.000 PM kernel[0]: PM notification timeout (pid 95130, Adobe CEF Helper)
A previous similar discussion tracked it down to a conflict with Symantec, but I don't have Symantec installed.
