How to Turn Off the Screen Saver on a Mac (Ventura to Tahoe)

To turn off the screen saver on a Mac, open System Settings, then Lock Screen, and set Start Screen Saver when inactive to Never. On macOS Monterey and older, it is in System Preferences, Desktop & Screen Saver. The display-off timer and the password delay are separate settings, and a Hot Corner can still start the screen saver. All of them, plus a Terminal command.

screen saver

To turn off the screen saver on a Mac, open System Settings, select Lock Screen in the sidebar, and set Start Screen Saver when inactive to Never. That works on macOS Ventura, Sonoma, Sequoia and Tahoe. On macOS Monterey and older, open System Preferences, Desktop & Screen Saver, the Screen Saver tab, and set the start time to Never.

Two other timers on the same Lock Screen page can still give you a dark or locked screen: Turn display off when inactive, and Require password after screen saver begins or display is turned off. And a Hot Corner can start the screen saver on demand. All four are below.

A screen that stays on does not keep chat apps active. Microsoft Teams reads input anywhere on the Mac; Slack counts only input inside its own window, and turns you grey after 10 minutes without it. Slack Green keeps your Slack status active from the cloud during the working hours you set, so the Mac can lock whenever it likes.

How to turn off the screen saver on a Mac: Lock Screen, Never; display off and password delay are separate

Turn off the screen saver on macOS Ventura, Sonoma, Sequoia and Tahoe

Turn off the screen saver on macOS Ventura to Tahoe: System Settings, Lock Screen, Never, Hot Corners

  • Open the Apple menu and choose System Settings.
  • Select Lock Screen in the sidebar. If you do not see it, type "Lock Screen" in the search field at the top of the sidebar.
  • Set Start Screen Saver when inactive to Never.
  • Open Desktop & Dock, select Hot Corners at the bottom, and set any corner that says Start Screen Saver to the dash (-).
  • The setting takes effect at once; no restart. If the menu is greyed out with a note that your organization manages it, the Mac has a configuration profile from IT, and only IT can change it.

    The Screen Saver page in System Settings is where you choose which screen saver runs. It no longer holds the timer; that moved to Lock Screen in macOS Ventura.

    Turn off the screen saver on macOS Monterey and older

  • Open Apple menu, System Preferences, Desktop & Screen Saver.
  • Select the Screen Saver tab.
  • Set Start after (called Show screen saver after on some versions) to Never.
  • Select Hot Corners on the same tab and clear any Start Screen Saver corner.
  • The Mac timers that give you a dark or locked screen

If you turn off the screen saver but leave the display timer at 10 minutes, the screen still goes black at 10 minutes, and many people read that as the screen saver. Set both.

Turn off the password after the screen saver

In Lock Screen, set Require password after screen saver begins or display is turned off to a longer delay, such as 1 hour, or to Never. macOS asks for your password to make the change.

Leave it on for a work Mac or any Mac in a shared space: without it, anyone who walks up can use the Mac. Many company Macs enforce a short delay through a profile, and that setting cannot be changed there. How locking works, and what to do on a managed Mac, is in keep a Mac screen from locking.

Turn off the screen saver from Terminal

The screen saver timer is stored per user and per Mac. This sets it to never:

defaults -currentHost write com.apple.screensaver idleTime -int 0

To check the value, and to put it back to 20 minutes (1,200 seconds) later:

defaults -currentHost read com.apple.screensaver idleTime
defaults -currentHost write com.apple.screensaver idleTime -int 1200

Open Lock Screen afterwards to confirm the menu shows the value you set. If you only need the screen on for a while, caffeinate -d keeps the display awake until you press Ctrl+C; every flag is in caffeinate on Mac. Menu-bar apps that do the same are compared in the best app to keep your Mac awake.

Mac screen saver keeps coming on

Mac screen saver keeps coming on: Hot Corners, managed profile, display off, other user account

  • • A Hot Corner. Moving the pointer into a corner set to Start Screen Saver starts it at once. Clear it in Desktop & Dock, Hot Corners.
  • • A managed profile. On a work Mac, IT can enforce a screen saver time. The setting reverts or shows a managed notice. Ask IT for a longer time.
  • • It is the display turning off. A black screen with no animation is the display timer. Lengthen Turn display off in Lock Screen.
  • • Another user account. The setting is per user. Change it while signed in as that user.
  • Does turning off the screen saver keep Teams or Slack active?

    It stops the lock that follows the screen saver, which matters because both apps show you as away when the Mac locks. It does not create input. Microsoft Teams still turns Away after about 5 minutes without keyboard or mouse input, as covered in how to keep Teams active on a Mac. Slack still turns grey after 10 minutes without input in the Slack window; the Mac options for Slack are in how to keep Slack active on a Mac.

    Quick answers

    Where is the screen saver setting in macOS Tahoe? System Settings, Lock Screen, Start Screen Saver when inactive.

    Why is Never missing from the menu? Your organization manages the setting, or the Mac uses an older macOS where the option is in Desktop & Screen Saver.

    Does turning off the screen saver use more battery? The screen saver itself does not save power; the display turning off does. Keep the display timer on for a MacBook on battery.

    How do I start the screen saver by hand? Set a Hot Corner to Start Screen Saver, or press Control-Command-Q to lock the screen instead.
