Fixed: MacBook Pro, Air, iMac Goes to Sleep randomly While in Use


One of the Mac users has a complaint that his MacBook Pro keeps going to sleep randomly. He said that it goes to sleep while in use. I also had this problem with my iMac. My iMac keeps going to sleep by itself. Then one of the Mac users said some solutions to fix this issue. Here I am going to share those solutions with you.
Why My MacBook Air/Pro keeps going to sleep unexpectedly?
In our Mac, we can set a time to make it sleep automatically. Many Mac users enable this option and say my mac keeps going to sleep by itself while in use.
How to prevent the Mac from going to sleep by itself?
Solution 1: Disable sleep timer

  1. Go to Apple Menu->System Preferences->Energy Saver.
  2. Select Power Adapter tab.
  3. There you can see two options: Computer sleep and Display Sleep. Set Computer sleep to Never and Display sleep to 15 min.
  4. To set them to Never, drag the slider until it reaches Never (at the right corner).

Note:  You can set the time to put your Mac sleep. It will automatically go to sleep when it reaches the time that you select (even it is in use).

  1. Go to Apple Menu->System Preferences->Mission Control.
