Mac, Tutorials

Are you tired of your Mac going to sleep every time you leave it idle for a few minutes? Don’t worry, there’s a simple solution to this problem. In this tutorial, we will guide you through the steps to make your Mac not sleep using a few easy settings adjustments.

Adjusting Energy Saver Preferences

To prevent your Mac from going to sleep, we will first need to modify the Energy Saver preferences. Here’s how:

  1. Click on the Apple menu located in the top-left corner of your screen.
  2. Select “System Preferences” from the drop-down menu.
  3. In the System Preferences window, click on the “Energy Saver” icon.

The Energy Saver preferences allow you to customize how your Mac behaves when idle or connected to a power source. We will now tweak these settings to ensure that your Mac stays awake.

Preventing Sleep When Using Power Adapter

If you want your Mac to stay awake even when it is connected to a power source, follow these steps:

  1. In the Energy Saver preferences window, make sure you are in the “Battery” tab.
  2. Uncheck the box next to “Put hard disks to sleep when possible“. This will prevent your hard drive from going into sleep mode.
  3. Move the “Computer sleep” slider all the way towards “Never“. This will ensure that your Mac never goes into sleep mode while connected to a power adapter.

Preventing Sleep When on Battery Power

If you want to stop your Mac from going to sleep when running on battery power, follow these steps:

  1. In the Energy Saver preferences window, switch to the “Power Adapter” tab.

    This will ensure that your Mac never goes into sleep mode when running on battery power.

  2. Select the checkbox next to “Prevent computer from sleeping automatically when display is off“. This will keep your Mac awake even if you turn off the display manually.

Tweaking Additional Settings

In addition to adjusting the Energy Saver preferences, there are a few more settings you can tweak to prevent your Mac from sleeping:

  1. Disable Screen Saver:
    • In System Preferences, click on “Desktop & Screen Saver“.
    • Select the “Screen Saver” tab and choose “No screen saver” from the list.
  2. Avoid Automatic Sleep:
    • In System Preferences, click on “Security & Privacy“.
    • Select the “General” tab and check the box next to “Require password immediately after sleep or screen saver begins“.


Congratulations! You have successfully configured your Mac to never go to sleep.

By adjusting the Energy Saver preferences and tweaking additional settings, you can now use your Mac without interruption. Whether you are working on important projects or enjoying media, your Mac will stay awake and ready for action.

Remember that keeping your Mac awake for extended periods may affect its overall performance and battery life. It’s recommended to allow your Mac to go to sleep when not in use for long durations or when running on battery power to conserve energy. However, with the settings we’ve covered in this tutorial, you can have more control over when your Mac goes to sleep.
