My iMac wakes up randomly when it is supposed to be asleep. I have checked the power saver and that seems all right. It seems to have started after I hooked it to AirPort Time Capsule, or not...
I use El Capitan and the computer is about 2 years old.
Thanks
iMac (27-inch, Late 2013), OS X El Capitan (10.11.3)
