How to stop a Mac from sleeping?

Like ourselves, a Mac needs to sleep. Remove mac apps completely. It’s a machine that needs to recharge. But there are times when you need it operating in wake mode. Either it’s processing something and can't shut down, or you are watching a movie or TV series and don't want to have to wake it up after a perceived period of inactivity.

Download Owly - Prevent Display Sleep for macOS 10.7 or later and enjoy it on your Mac. ‎Say hello to Owly, a cute little fellow who lives in your Mac’s menu bar and does its best to prevent your Mac from automatically sleeping. It can prevent the screensaver from starting and stop the screen or computer from being put to sleep. StayAwake does this by fooling Windows and telling it the mouse cursor has moved zero pixels. Simply launch the portable executable and double click the tray icon to enable or disable StayAwake’s function.

Here are the steps you should take for keeping a Mac awake:

  1. Go to the Apple menu in the top toolbar > System Preferences
  2. Click on Energy Saver;
  3. Now you have a wide range of options for controlling sleeping and waking times and cycles:
  • Use the slider to determine when exactly a Mac goes to sleep after a period of inactivity;
  • You can even keep it awake indefinitely, although that isn't recommended for long periods of time;
  • Another setting can be ticked or unticked to “Put hard disks to sleep when possible”;
  • Also a useful setting for those needing to keep a Mac awake for a while: “Prevent computer from sleeping automatically when the display is off”;
  • If you need others to access your Mac, the following is a useful setting: “Wake for network access.”

There are a number of third-party apps that give you a range of features beyond what is built-into macOS. Some of them are worth downloading and taking for a spin. Another app that can solve problems with a Mac’s sleep and waking cycle is CleanMyMac X.
