Are you tired of your Mac screen going dark on you at the most inconvenient times? You’re not alone! This frustrating issue can be a real productivity killer, especially when you’re in the middle of an important task or watching a thrilling video. But don’t worry, we’ve got you covered! In this comprehensive guide, we’ll explore the reasons behind this issue and provide you with actionable tips to keep your Mac screen shining bright.
Why Does My Mac Screen Go Dark?
Before we dive into the solutions, let’s first understand why your Mac screen goes dark in the first place. There are several reasons that can cause this issue:
Power Nap Feature
The Power Nap feature is a built-in functionality in Macs that allows your computer to update itself and perform maintenance tasks even when it’s asleep. While this feature is designed to be energy-efficient, it can sometimes cause your screen to go dark, especially if you’re not using your Mac for an extended period.
Screen Saver Settings
Your Mac’s screen saver settings can also cause the screen to go dark. If you’ve set your screen saver to activate after a certain period of inactivity, it can mistakenly think you’re not using your Mac and turn off the screen.
Battery Life Conservation
To conserve battery life, your Mac may automatically dim or turn off the screen when the battery level falls below a certain threshold. This feature is designed to prolong your Mac’s battery life, but it can be annoying if you’re not expecting it.
Automatic Graphics Switching
Some Macs come with automatic graphics switching, which allows your computer to switch between integrated and discrete graphics cards to conserve power. However, this feature can sometimes cause the screen to go dark or flicker.

Why Does My Mac Screen Keep Going Dark?
Your Mac screen is designed to go dark or turn off automatically to conserve energy and prolong battery life. This is a default feature in Mac computers, especially those with portable devices like laptops. The screen dimming or turning off is triggered by inactivity, which means that if you’re not interacting with your Mac for a certain period, the screen will automatically go dark. This feature can be adjusted or turned off in the system settings.
To adjust the screen timeout, go to System Preferences > Energy Saver (or Battery on some Mac models). Look for the “Turn display off after” slider and adjust it to your desired time. You can also uncheck the “Automatic brightness adjustment” option to disable automatic screen dimming.
How Do I Turn Off The Screen Timeout On My Mac?
To turn off the screen timeout on your Mac, you need to adjust the Energy Saver settings. You can do this by going to System Preferences > Energy Saver (or Battery on some Mac models). Look for the “Turn display off after” slider and move it all the way to “Never”. This will disable the screen timeout feature, and your Mac screen will no longer turn off automatically due to inactivity.
Keep in mind that disabling the screen timeout may affect your Mac’s battery life, especially if you’re using a laptop. It’s recommended to adjust the timeout duration instead of turning it off completely, especially if you’re concerned about battery life.
Can I Adjust The Screen Brightness On My Mac?
Yes, you can adjust the screen brightness on your Mac to your desired level. You can do this using the keyboard shortcuts or through the System Preferences. To adjust the screen brightness using the keyboard, press the F1 or F2 keys (or the corresponding function keys on your Mac). You can also go to System Preferences > Displays and adjust the “Brightness” slider to your desired level.
Additionally, you can also adjust the auto-brightness feature, which adjusts the screen brightness based on the ambient lighting around you. To do this, go to System Preferences > Displays and check or uncheck the “Automatically adjust brightness” option.
What Is The Auto-brightness Feature On My Mac?
The auto-brightness feature on your Mac is a built-in feature that adjusts the screen brightness based on the ambient lighting around you. This feature uses the ambient light sensor on your Mac to detect the surrounding light and adjust the screen brightness accordingly. When enabled, the auto-brightness feature can help reduce eye strain and conserve battery life.
To enable or disable the auto-brightness feature, go to System Preferences > Displays and check or uncheck the “Automatically adjust brightness” option. You can also adjust the screen brightness manually using the keyboard shortcuts or through the System Preferences.
How Do I Keep My Mac Screen From Going Dark When Watching Videos?
When watching videos on your Mac, you can prevent the screen from going dark by adjusting the system settings or using third-party apps. One way to do this is to adjust the Energy Saver settings to “Never” turn off the display, as mentioned earlier. Another way is to use third-party apps like Caffeine or Amphetamine, which can temporarily prevent your Mac from going to sleep or turning off the screen.
Additionally, you can also adjust the video player settings to prevent the screen from turning off. For example, in QuickTime Player, you can go to QuickTime Player > Preferences > Advanced and check the “Prevent screen from dimming” option.
Can I Set A Keyboard Shortcut To Prevent My Mac Screen From Going Dark?
Yes, you can set a keyboard shortcut to prevent your Mac screen from going dark using third-party apps like Caffeine or Amphetamine. These apps allow you to set a keyboard shortcut to temporarily prevent your Mac from going to sleep or turning off the screen. You can also use other third-party apps that offer similar features.
To set a keyboard shortcut, you’ll need to download and install the third-party app, then follow the app’s instructions to set the shortcut. For example, in Caffeine, you can go to Caffeine > Preferences and set the keyboard shortcut under the “Hot Key” section.
Is It Safe To Disable The Screen Timeout On My Mac?
Disabling the screen timeout on your Mac can be safe as long as you’re aware of the potential consequences. Disabling the screen timeout can lead to reduced battery life, especially if you’re using a laptop. Additionally, it can also lead to increased eye strain and fatigue if you’re working on your Mac for extended periods.
However, if you’re using your Mac in a stationary setup or have a reliable power source, disabling the screen timeout may not be a concern. It’s also recommended to adjust the screen timeout duration instead of disabling it completely to strike a balance between convenience and battery life.
