Whenever I turn my iMac to sleep mode (log off but don't turn off), it re-awakes without my prompting. The screen does not fully turn off and then sometimes opens without me being close to my computer. Please help!
iMac, iOS 12
Turn off Power Nap in System Preferences > Energy Saver.
If turning off power nap does not help then FWIW, I gave up on the Sleep function years ago. Ever since the inception of OS X there have been Sleep related issues. And even more lately. I just use Display Sleep and keep it set for 15 minutes so I'm not burning the screen. That way your Mac uses very little power over Sleep and is ready to use at the touch of a key without any grogginess. UNIX based systems were made to be always on and they’ve been running busy servers 24/7 for decades.
