Mac, Tutorials

Are you tired of your Mac screen constantly timing out and going to sleep? Changing the screen timeout settings on your Mac is a simple and effective way to customize your computer’s behavior. In this tutorial, we will guide you through the process of changing the screen timeout on your Mac.

Step 1: Accessing System Preferences

To change the screen timeout on your Mac, you need to access the System Preferences. Click on the Apple menu in the top-left corner of your screen, and then select “System Preferences” from the drop-down menu. Alternatively, you can use the keyboard shortcut “Command + Space” to open Spotlight Search and type “System Preferences” before hitting Enter.

Step 2: Opening Energy Saver Preferences

Once you have opened System Preferences, locate and click on the “Energy Saver” icon. It usually features a light bulb or a battery icon. The Energy Saver preferences panel allows you to manage various power-related settings on your Mac.

Step 3: Adjusting Screen Sleep Time

In the Energy Saver preferences panel, you will see two sliders labeled “Turn display off after” and “Put hard disks to sleep when possible.” The first slider controls how long it takes for your Mac’s screen to go to sleep when inactive. Click and drag this slider to adjust the screen sleep time according to your preference.

Note: Moving the slider towards “Never” will prevent your screen from timing out altogether.


  • If you want more control over when your Mac goes to sleep, consider using third-party applications like Amphetamine or Caffeine that allow you to override system settings temporarily.
  • If you are using a MacBook, you can also adjust the screen timeout settings based on whether your device is running on battery power or connected to a power adapter. Simply click on the “Battery” and “Power Adapter” tabs in the Energy Saver preferences panel to set different screen sleep times for each scenario.

Step 4: Saving Changes

Once you have adjusted the screen sleep time to your liking, close the Energy Saver preferences panel. Your changes will be automatically saved and take effect immediately.

Congratulations! You have successfully changed the screen timeout settings on your Mac. Now you can enjoy uninterrupted work or leisure without constantly having to wake up your computer.

Remember: Conserving energy by allowing your Mac’s screen to go to sleep when idle can help prolong battery life and reduce electricity consumption.

We hope this tutorial has been helpful in guiding you through the process of changing the screen timeout on your Mac. If you have any further questions or need additional assistance, feel free to reach out to Apple Support or consult official Apple documentation.
