Does your MacBook act like Rapunzel? Sleeping away the minute you leave it unattended? If yes, it’s time to do something about it.

Entering your password repeatedly can be frustrating and kills precious time. Therefore, save yourself from this trouble and learn to change your screen’s lock time on Mac.

Without further ado, let’s learn to stop your Mac from going to sleep by changing your screen’s timeout on your Mac.

Why MacBook Switches to Lock Screen Automatically

Several reasons may be responsible for your MacBook to sleep and switch to the lock screen automatically. For instance, a magnet might be placed near your device, causing interference with the operating system.

Another reason your MacBook switches to a lock screen may be that you have enabled hot corners that activate whenever your laptop is inactive. We will learn about them later in the article.

Furthermore, your Energy Saver feature might be misconfigured, causing changes in your lock screen timeout. We will learn more about configuring these correctly in the following read.

How to change Screen Timeout on a Mac

It’s possible to change your screen timeout time based on your preferences. Following are some of the ways:

Change Screen Timeout through the Energy Saver Option

The first method for changing timeout is by following the steps below:

  1. Click on the Apple menu
  2. Select System Preferences
  3. Next, Select the Energy Saver option
  4. Look for a lock symbol on the bottom left corner of your screen
  5. Enter log in details (user name and password)
  6. Use the scroll bar to adjust the screen timeout

Finally, you can change your Mac’s timeout according to your preferences.

  2. Select Battery
  3. Choose Power Adapter
  4. Glide the slider to your preferable time

At last, you will set up a timeout for your Mac while it’s plugged in.

  3. Next, choose Energy Saver
  4. On the bottom left corner of the screen, click on the padlock icon

  7. Also, tick the check box “Prevent the computer from sleeping automatically when the display is off.”

Finally, your computer screen cannot go to sleep mode.
