Where to find screen timeout settings on your Mac

Screen timeout on a Mac is controlled through System Settings under the Energy Saver or Battery settings, depending on whether you have a laptop or desktop. The setting tells your Mac how long to wait before the display goes dark when you stop using the keyboard and trackpad. You can set different timeouts for when your Mac is plugged in versus running on battery.

The exact path varies slightly by macOS version, but the principle is the same across recent versions. You will navigate to System Settings, then find the power or energy section, and adjust the display sleep timer from there. The process takes less than a minute once you know where to look.

Key Takeaways

  • Open System Settings, then go to General > Locks & Security or Energy Saver to find display timeout options.
  • You can set different timeouts for when your Mac is plugged in and when it is on battery power.
  • Shorter timeouts save battery life and improve security; longer timeouts keep your screen on during presentations or reading.
  • The setting applies to display sleep only — your Mac can continue running background tasks even after the screen goes dark.

Steps to change display sleep time on macOS Sonoma and newer

Click the Apple menu in the top-left corner and select System Settings. In the sidebar, click General, then scroll down and click Locks & Security. Look for the section labeled "Turn display off after" and use the dropdown menu to choose your preferred time interval.

The options typically range from 1 minute to Never. If you select Never, your display will stay on indefinitely until you manually turn it off or your Mac goes to sleep for other reasons. After you make your choice, the setting takes effect when ready — you do not need to restart or confirm anything.

Steps to change display sleep time on macOS Ventura and earlier

Click the Apple menu and select System Settings (or System Preferences on older versions). In the sidebar, click Battery (on laptops) or Energy Saver (on desktops). You will see two sections: one for when your Mac is on battery power and one for when it is plugged in.

Under each section, find the slider or dropdown labeled "Turn display off after" and adjust it to your preferred time. Common options include 1 minute, 5 minutes, 10 minutes, 15 minutes, 30 minutes, 1 hour, and Never. Make separate choices for battery and plugged-in modes if you want different behavior in each situation.

Why you might want to change your timeout setting

A shorter timeout — such as 1 or 5 minutes — saves battery power on laptops and reduces energy use on desktops. It also locks your screen faster if you step away from your Mac, which improves security if you work in a shared space. Many workplaces require a display timeout of 15 minutes or less for this reason.

A longer timeout or Never is useful if you are reading documents, watching videos, or giving a presentation and do not want the screen to go dark while you are actively using your Mac. You can always wake the display by moving your mouse or pressing a key, so a short timeout does not prevent you from using your Mac — it just means you have to wake it more often.

The difference between display sleep and Mac sleep

Display sleep and Mac sleep are not the same thing. When your display times out and goes dark, your Mac itself is still running. Background tasks, downloads, and other processes continue. Your Mac will sleep separately after a longer period of inactivity, which you can also control in the same Energy Saver or Battery settings.

If you want your Mac to sleep faster than your display, you can set a shorter display timeout and a longer Mac sleep time. For example, your display might go dark after 5 minutes, but your Mac might not sleep until 30 minutes of inactivity. This keeps your Mac responsive while still saving power and locking your screen.

Adjusting timeout for different power sources

On a MacBook, you can set different timeouts for battery mode and plugged-in mode. When you are on battery power, a shorter timeout saves charge. When your Mac is plugged in, you might prefer a longer timeout since power consumption is not a concern. The settings are in the same Energy Saver panel — just adjust the slider for each scenario separately.

Desktop Macs do not have battery mode, so you will see only one timeout setting. If you use a desktop Mac in a shared office or library, a 15-minute timeout is a common choice that balances convenience with security.

What to do if your screen times out too quickly

If your display keeps going dark while you are using your Mac, increase the timeout value. Open System Settings, navigate to the power settings, and move the slider to a longer interval. If you are reading or watching something that does not require keyboard or trackpad input, you may need to set the timeout to Never or move your mouse occasionally to keep the display awake.

Some applications, such as presentation software or video players, can override the timeout setting and keep your display on automatically. If you are using one of these apps and the screen still goes dark, check the app's own settings for a full-screen or presentation mode that disables sleep.

Frequently Asked Questions

Can I set different timeouts for different users on the same Mac?

Yes. Each user account on your Mac has its own settings. When you log in as a different user, you can open System Settings and adjust the timeout for that account independently. The settings do not affect other users on the same Mac.

Does changing the display timeout affect my Mac's performance?

No. The timeout setting only controls when the display goes dark. It does not change how fast your Mac runs or how much processing power it uses. A shorter timeout saves electricity, but it does not make your Mac slower or faster.

What happens if I set the timeout to Never?

Your display will stay on until you manually turn it off or your Mac goes to sleep for another reason. This uses more power on a laptop and more electricity on a desktop. If you forget to turn off your Mac, the display could stay on for hours.

Can I wake my Mac from display sleep without using the keyboard?

Yes. Moving your trackpad or mouse will wake the display. On some Macs, you can also wake the display by pressing any key on the keyboard. The exact behavior depends on your Mac model and macOS version.

Why does my Mac have different timeout options than what I see in the instructions?

macOS updates change the location and wording of settings. If you cannot find the option described here, search for "display sleep" or "turn display off" in the System Settings search bar at the top of the window. This will take you directly to the right setting regardless of your macOS version.
