5 Ways to prevent Mac from Sleeping on macOS Ventura
Here are some of the easy ways to prevent your Macbook or Mac Desktop from entering Sleep Mode.
Note – Remember that preventing your Mac from entering sleep mode can impact energy consumption and battery life. Use these methods judiciously based on your specific needs and preferences.
1) Adjusting System Preferences for Customised Sleep Settings
The most straightforward and most user-friendly method to prevent your Mac from sleeping involves navigating System Preferences.
Begin by clicking on the Apple logo in the top-left corner, selecting “System Preferences,” and then choosing “Energy Saver.” Within this menu, you’ll find options for adjusting sleep settings for battery and power adapter modes.
Change the “Computer sleep” duration to extend the time before your Mac enters sleep mode or set it to “Never” for an indefinite wakefulness period.
Here are the exact steps and images for the same.
a) Click on the Apple Logo
In the top-left corner of your screen, click on the Apple icon to open the Apple menu.
b) Select “System Preferences“
From the dropdown menu, choose “System Preferences.”
The other method to open system preferences is to use the Apple Dock to access the system settings.
c) Navigate to “Lock Screen”
In the System Preferences window, look for the “Lock Screen” icon and click on it.
The image shows you can also use the search box to find the Lock Screen in the system preferences tab.
d) Adjust Sleep Settings
Within the Energy Saver preferences, you’ll find options for both “Battery” and “Power Adapter” modes.
Adjust the “Sleep or Screen Saver” time to a longer duration or set it to “Never” if you want to disable sleep mode entirely.
e) Click “Apply”
If you are on a different macOS than macOS Ventura, click the “Apply” button to save the new settings.
However, on the macOS Ventura, the settings will apply on changing the time.
2) Terminal Commands for Fine-Tuned Control
For users comfortable with Terminal and seeking more granular control, here is another way to turn off sleep mode on Macbook or Mac Desktops.
a) Open Terminal
Launch the Terminal application. You can find it in the Applications > Utilities folder
b) Enter Terminal Command
To disable sleep, enter the following command.
Here, 3600 represents the number of seconds (60 seconds/minute x 60 minutes/hour), and you can adjust this value to your desired duration. After the specified time, your Mac will return to its normal sleep behaviour.
If you want to completely turn off the Screen Saver mode on your Mac, type the following command.
Press Enter and input your administrator password when prompted.
3) Leveraging Activity Monitor to Indirectly Prevent Sleep
While not a direct sleep prevention method, Activity Monitor, a built-in utility on macOS, can be leveraged to maintain wakefulness.
Keeping Activity Monitor open and visible on your desktop generates continuous system activity, preventing your Mac from entering sleep mode during periods of low user interaction.
4) Third-Party Applications for Enhanced Flexibility
Third-party applications come to the rescue for those desiring more granular control and a user-friendly interface.
Apps like Amphetamine, Caffeine, and KeepingYouAwake provide easy access to toggle sleep settings from the menu bar.
These applications allow users to prevent sleep for specific durations, indefinitely, or until a particular task is completed, offering a more dynamic approach to managing Mac wakefulness.
5) Using Network Activity as a Preventive Measure
To counteract the default sleep mode triggered by a lack of network activity, engage in tasks that generate continuous network traffic. Streaming music or videos and running network pings through the Terminal are effective strategies to simulate activity and keep your Mac awake when needed.
Here is a video showing how a Ping Test works.
Not to forget, I recommend trying out others methods mentioned in this list before you try out this way of keeping your Mac active.
