How to stop a Mac from sleeping?
Like ourselves, a Mac needs to sleep. 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.
Here are the steps you should take for keeping a Mac awake:
- Go to the Apple menu in the top toolbar > System Preferences
- Click on Energy Saver;
- 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.”

Want to leave your Mac on for a while for some process to finish? The default behavior in OS X is to put the computer into a low power sleep mode after a couple of minutes of inactivity. While this is great for saving energy, you may find it interfering with your computer usage.
Permanent solution
Open System Preferences, and go to Energy Saver section. Here you see two sliders for Computer Sleep and Display Sleep. The sliders range from 1 minute, to Never. Use the sliders to adjust the sleep behavior to suit your needs. If you have a portable Mac, there are separate settings for Battery powered operation and for Power Adapter. You may disable sleep altogether but putting the slider on “Never”, just beware that it will increase your energy usage, and likely cause more wear on the system.
Occasional solution
This handy Caffeine app can prevent your Mac from entering sleep mode on demand. An icon in the menu bar will allow you to toggle the setting for those occasional times when you need to computer to run uninterrupted. Click on the cup to toggle Caffeine. System settings apply when the cup is empty, and Caffeine is working when the cup is full. Very convenient and free.
