Mac, Tutorials

Do you find it frustrating when your Mac goes to sleep too quickly? You’re in the middle of something important, and suddenly, the screen turns off, and you have to wake it up again.

Luckily, there are ways to adjust the sleep settings on your Mac to prevent it from dozing off so fast. In this article, we will guide you through the steps to stop your Mac from sleeping too quickly.

Adjusting Sleep Settings

If you want to prevent your Mac from sleeping too quickly, you can modify its sleep settings. Here’s how:

Step 1: Open System Preferences

To begin, click on the Apple menu in the top-left corner of your screen and select “System Preferences” from the drop-down menu. Alternatively, you can use the shortcut by pressing “Command + comma” keys simultaneously.

Step 2: Select Energy Saver

In the System Preferences window, locate and click on the “Energy Saver” icon. This will open a new window with various power-related settings.

Step 3: Adjust Sleep Settings

In the Energy Saver window, navigate to the “Battery” tab if you are using a MacBook or MacBook Pro. For desktop Macs like iMac or Mac Pro, select the “Power Adapter” tab.

Within this tab, you’ll see a slider labeled “Turn display off after.” This slider determines how quickly your Mac’s display turns off when inactive.

Adjust this slider according to your preference. Moving it towards “Never” will prevent your display from turning off automatically.

  • Note:
    • If you are using a laptop on battery power and want to conserve battery life, you may want to set a shorter duration for the display to turn off.
    • On the other hand, if you are using a desktop Mac and don’t require power-saving measures, setting it to “Never” may be more suitable.

Additionally, you can adjust the “Put hard disks to sleep when possible” option. When selected, this option allows your Mac’s hard drive(s) to spin down when idle for an extended period. Depending on your needs, you can enable or disable this feature.

Step 4: Save Changes

Once you have made the desired adjustments, click on the “Save” button at the bottom right corner of the Energy Saver window. Your changes will now take effect.

Note: Keep in mind that adjusting sleep settings can impact power consumption and battery life depending on your Mac model and usage patterns. Make sure to find a balance between keeping your Mac awake and conserving energy.

Prevent Sleep Temporarily

If you only need to prevent your Mac from sleeping temporarily—such as during a presentation or while watching a movie—you can use the built-in “Caffeinate” command in Terminal.

Step 1: Open Terminal

To launch Terminal on your Mac, go to “Applications” > “Utilities” > “Terminal.” You can also search for “Terminal” using Spotlight by pressing “Command + Spacebar” and typing “Terminal.”

Step 2: Enter Caffeinate Command

In the Terminal window, type in the following command:

caffeinate -s

This command will prevent your Mac from going to sleep as long as the Terminal window is open.

Note: If you want to prevent your Mac from sleeping for a specific duration, you can use the “-t” flag followed by the number of seconds. For example, “caffeinate -t 3600” will keep your Mac awake for one hour.

Conclusion

By adjusting the sleep settings on your Mac or using the Caffeinate command in Terminal, you can prevent your Mac from sleeping too quickly. Whether you need to keep it awake for work or entertainment purposes, these methods provide flexibility and control over your Mac’s sleep behavior.

Remember to find a balance between keeping your Mac awake and conserving energy to optimize performance and battery life.

Now that you know how to stop your Mac from sleeping so fast, put these tips into practice and enjoy uninterrupted productivity on your Apple device!
