How to Change the Screen Saver Timeout on Mac

If you'd prefer to have a screen saver kick in after a certain length of time, here's how to adjust how long it takes.

1. Click the Apple logo.

   

2. Click System Preferences.

   

3. Click Desktop & Screen Saver.

   

4. Click Screen Saver.

   

5. Choose your screensaver.

6. Tick Show Screen saver after.

   If you see a yellow warning icon next to this, it means that your Mac's display is set to switch off before the screen saver has a chance to begin.

Why Would I Change My Screen Timeout?

Many people will be happy with the default Mac screen timeout options. However, there are some cases where you may want to increase or reduce the time. Here's a look at them.

• Privacy. Decreasing the length of time before the screen times out means that your screen isn't visible for as long, which can be useful if you want to keep something private.
• Giving presentations. If you're trying to show someone something on screen without interacting for a while, a longer screen timeout means the screen won't switch off midway through the presentation. This also applies when listening to music.
• To save battery life. If you regularly use your Mac on battery power, a lower screen timeout means that you'll conserve battery life any time you're not using it.
