Are you tired of your Mac screen turning off at the most inopportune moments? Do you find yourself constantly adjusting the display settings to keep your screen on? You’re not alone. Many Mac users struggle with the default screen timeout settings, which can be frustrating and disrupt your workflow. In this article, we’ll explore the reasons behind the screen timeout and provide step-by-step instructions on how to change when your Mac screen turns off.
Understanding the Screen Timeout Feature
The screen timeout feature is designed to conserve energy and prolong the lifespan of your Mac’s display. When your Mac is idle for a specified period, the screen will automatically turn off to prevent unnecessary power consumption. This feature is especially useful for laptops, as it helps to extend battery life. However, for desktop users or those who prefer to keep their screen on for extended periods, the default timeout settings can be annoying.
Why Does My Mac Screen Keep Turning Off?
There are several reasons why your Mac screen might be turning off more frequently than you’d like. Here are a few possible explanations:
- Default timeout settings: The default screen timeout settings on Macs are typically set to turn off the display after a short period of inactivity, usually 2-5 minutes.
- Power-saving features: Macs have built-in power-saving features that can cause the screen to turn off when the system is idle. These features are designed to conserve energy and prolong battery life.
- Display settings: The display settings on your Mac can also affect the screen timeout. For example, if you have the “Turn off display after” option set to a short period, the screen will turn off accordingly.
Changing the Screen Timeout Settings on Your Mac
Fortunately, changing the screen timeout settings on your Mac is a straightforward process. Here’s how to do it:
Method 1: Adjusting the Display Settings
- Click the Apple menu and select “System Preferences.”
- Click on “Energy Saver” (for older Macs) or “Battery” (for newer Macs).
- Click on the “Options” tab.
- Select the “Turn off display after” dropdown menu and choose your desired timeout period.
- You can also select the “Prevent computer from sleeping automatically when the display is off” checkbox to prevent your Mac from sleeping when the screen is off.
Method 2: Using the Terminal App
If you’re comfortable using the Terminal app, you can use the following command to change the screen timeout settings:
- Open the Terminal app on your Mac.
- Type the following command:
defaults write com.apple.screensaver idleTime <timeout_value> - Replace
<timeout_value>with your desired timeout period in seconds (e.g., 300 for 5 minutes). - Press Enter to execute the command.
Additional Tips to Keep Your Mac Screen On
In addition to changing the screen timeout settings, here are some additional tips to help keep your Mac screen on:
- Use the “Hot Corners” feature: You can set up the “Hot Corners” feature to prevent your Mac from sleeping or turning off the display when you’re not actively using it. To do this, go to System Preferences > Mission Control > Hot Corners, and select the “Prevent sleeping” option.
- Disable the “Turn off display after” option: If you don’t want your Mac screen to turn off at all, you can disable the “Turn off display after” option altogether. To do this, go to System Preferences > Energy Saver > Options, and uncheck the “Turn off display after” checkbox.
- Use a third-party app: There are several third-party apps available that can help keep your Mac screen on, such as Caffeine, Amphetamine, or KeepingYouAwake. These apps can override the default screen timeout settings and keep your screen on for as long as you need.

Remember to also explore the additional tips and tricks to get the most out of your Mac’s display settings.
Why does my Mac screen turn off automatically?
Your Mac screen may turn off automatically due to the default Energy Saver settings. This feature is designed to conserve energy and prolong the lifespan of your Mac’s display. When your Mac is inactive for a certain period, the screen will turn off to save power. You can adjust these settings to change the duration or turn off the feature altogether.
To adjust the Energy Saver settings, go to System Preferences, click on Energy Saver, and adjust the slider to set the desired duration for your Mac’s screen to turn off. You can also select the “Prevent computer from sleeping automatically when the display is off” checkbox to prevent your Mac from sleeping when the screen is off.
How do I stop my Mac screen from turning off?
To stop your Mac screen from turning off, you can adjust the Energy Saver settings or use a third-party app. Go to System Preferences, click on Energy Saver, and move the slider to the “Never” position. This will prevent your Mac screen from turning off automatically. Alternatively, you can use a third-party app like Caffeine or Amphetamine to keep your Mac awake and prevent the screen from turning off.
Keep in mind that keeping your Mac screen on for extended periods can consume more power and reduce the lifespan of your display. It’s essential to find a balance between convenience and energy efficiency. You can also set your Mac to turn off the screen after a certain period of inactivity to conserve energy.
What is the difference between sleep and screen off on a Mac?
When your Mac goes to sleep, the entire system is put into a low-power state, and all activities are paused. The screen will turn off, and your Mac will consume minimal power. On the other hand, when your Mac screen turns off, only the display is turned off, and your Mac remains active and continues to run tasks in the background.
The main difference between sleep and screen off is that sleep mode pauses all activities, while screen off only turns off the display. If you’re working on a task that requires your Mac to be active, you may want to keep the screen on or use a third-party app to keep your Mac awake.
Can I set my Mac to turn off the screen after a certain period of inactivity?
Yes, you can set your Mac to turn off the screen after a certain period of inactivity. Go to System Preferences, click on Energy Saver, and adjust the slider to set the desired duration for your Mac’s screen to turn off. You can choose from a range of options, from 1 minute to 3 hours, or select “Never” to prevent the screen from turning off automatically.
Additionally, you can set your Mac to turn off the screen when you’re not actively using it. For example, you can set the screen to turn off after 10 minutes of inactivity when you’re watching a movie or 30 minutes when you’re working on a task.
Will keeping my Mac screen on all the time damage the display?
Keeping your Mac screen on for extended periods can potentially reduce the lifespan of your display. Modern Mac displays are designed to withstand prolonged use, but excessive screen time can cause wear and tear. However, the impact is minimal, and you’re unlikely to notice a significant difference.
To minimize the risk, you can adjust the Energy Saver settings to turn off the screen after a certain period of inactivity. You can also use a screen saver to reduce the strain on your display. Additionally, make sure to update your Mac’s software regularly, as newer updates often include display-related improvements.
Can I use a third-party app to keep my Mac screen on?
Yes, you can use a third-party app to keep your Mac screen on. Apps like Caffeine and Amphetamine can prevent your Mac from sleeping and keep the screen on for as long as you need. These apps are designed to override the Energy Saver settings and keep your Mac awake, even when you’re not actively using it.
Third-party apps can be useful if you need to keep your Mac screen on for an extended period, such as when you’re working on a task that requires your Mac to be active or when you’re watching a movie. However, be cautious when using these apps, as they can consume more power and reduce the lifespan of your display.
How do I reset the Energy Saver settings to their default values?
To reset the Energy Saver settings to their default values, go to System Preferences, click on Energy Saver, and click on the “Restore Defaults” button at the bottom of the window. This will reset the Energy Saver settings to their original values, which are set by Apple.
Resetting the Energy Saver settings can be useful if you’ve made changes and want to revert to the default settings. Keep in mind that resetting the settings will also reset any customizations you’ve made, so you may need to re-adjust the settings to your liking.
