In some cases, it is inconvenient to leave your Mac to work on its own, especially when loading a large file or exporting a video. When you check the result after a while, you see that it has not progressed nearly anything because it automatically switched to sleep mode and stopped working.
And while sleep mode is helpful in many cases, it can also be highly irritating in others. If you prefer your Mac not to sleep automatically after a few minutes of inactivity, we will show you how to disable this option completely.
Let’s look through several ways how to keep your MacBook from sleeping.
By using the Energy Saver option in System Preferences, you can change your Mac settings to disable automatic sleep mode.
Let’s see how to turn off sleep mode if you are using macOS Monterey and Big Sur:
1. Go to System Preferences.
2. Select Battery from the settings menu.
3. Choose Power Adapter.
4. Click the lock icon to be able to make the changes.
5. Enter your Mac login and password, then click Modify Settings.
6. Then you can modify the time when you want your Mac to turn off.
Once you’ve set this up, your Mac will not use the sleep mode by default. Of course, if you change your mind in the future, you can go back to this section in your Mac’s settings, and set your computer again to go to sleep mode after a specific time automatically.
Here’s how to turn off sleep mode on macOS Catalina and earlier:
1. Click on the Apple logo and go to System Preferences.
2. Select Energy Saver from the settings menu.
3. Inside the window, you’ll see a little slider at the top called Computer Sleep. Drag it to the very right edge, up to where it says Never.
4. A warning will appear, indicating that Your Mac may use more energy with these settings. You need to click on the accept button.
Every Mac computer can be forced to stay awake for a specific amount of time if needed. And it is done quite simply – the only thing you need is to be able to convert time into seconds.
To disable sleep mode using Terminal:
1. Open Terminal from the Finder.
2. Type caffeinate -t [number of seconds].
3. After typing the command, press the Enter key. After that, the Terminal will display a new empty line, and your Mac will not fall asleep for the time you specified in the command.
Pro bonus: You can easily convert hours to seconds via the Spotlight window. Just type in the needed number of hours, and you will see the converted time in seconds.
If you are not into digging into the Mac settings or using complex commands in Terminal, there is another way out. You can use third-party apps to ensure it will not go to sleep mode. Let’s look at some of them.
Owly is a toll-free app that helps you to prevent Mac from sleeping. You can download it from App Store. With Owly, your Mac can be awake from 5 minutes to infinity. The app can be turned on or off by right-clicking the Owly icon in the menubar. When the Owly icon is red means that the sleep mode is disabled. When it turns to be black – the sleep mode works by default.
Amphetamine is a keep-awake-free app for your Mac. It is a helpful app for anyone who doesn’t want their Mac’s screen to go dim at the most inappropriate moment. The app is available to be downloaded from the App Store.
The app has several modes to set up. You can choose from
Theine is another app that prevents your Mac from falling asleep. It is not free. The price on the App Store is $4.99. With several clicks, you can easily set up the time when you want your Mac to be awake. It offers much more features than free apps.
Now you know how to prevent your Mac from sleeping. As you see, you don’t need much time or effort to do that. You can do that manually by changing Energy Saving settings or using the Terminal commands. Another way is using the specialized applications we’ve told you about.
Sleep mode is a default setting that allows you to suspend your MacBook without shutting it down.
All unsaved documents and running applications are stored in the RAM in sleep mode. However, it doesn’t consume much energy. Your Mac is almost instantly ready to go when you resume sleep mode.
You can set your laptop to turn on and off automatically.
If you have macOS Monterey or Big Sur follow the next steps:
1. Click on the Apple logo, and select System Preferences > Battery.
2. Choose the Schedule menu and set up the power off schedule.
Here is how to do this on macOS Catalina and earlier:
1. Click on the Apple logo, and select System Preferences > Energy Saver.
2. Click on the Schedule button.
3. In the window that opens, specify what days and what time to turn it on and off.
4. Click OK.
With a sleep mode, Mac’s RAM stays powered on, making it possible to wake up Mac quickly and get to work almost immediately.
Before putting the Mac to sleep mode, the startup drive saves information from RAM for safekeeping. Once you wake up your Mac, the startup disk will recover all data back to the RAM. That is why it takes a longer time to turn on the Mac.
The startup drive saves the information in safe mode before your Mac goes to sleep. However, using the safe mode enables you to retrieve your data in case of any failures.
Standby mode is mainly used to save battery. Before entering the standby mode all the current processes are stored on a hard drive.
