Are you tired of your Mac falling asleep every time you close the lid? Do you wish there was a way to keep your Mac awake and running even when the lid is closed? You’re not alone. Many Mac users have struggled with this issue, especially those who use their Macs for tasks that require continuous running, such as video rendering, file transfers, or server hosting.
In this article, we’ll explore the reasons why your Mac goes to sleep when you close the lid and provide you with step-by-step instructions on how to prevent it from doing so. We’ll also discuss the potential risks and benefits of keeping your Mac awake and provide you with some useful tips and tricks to help you get the most out of your Mac.
Why Does My Mac Go to Sleep When I Close the Lid?
Before we dive into the solution, let’s first understand why your Mac goes to sleep when you close the lid. The reason is simple: it’s a power-saving feature designed to conserve battery life. When you close the lid, your Mac assumes that you’re not using it and goes into sleep mode to reduce power consumption. This feature is enabled by default on all Macs, and it’s a great way to prolong battery life when you’re on the go.
However, there are situations where you might want to keep your Mac awake even when the lid is closed. For example, if you’re using your Mac as a server or for tasks that require continuous running, you’ll want to keep it awake to ensure that the task is completed.

What is the purpose of keeping a Mac awake when closing the lid?
Keeping a Mac awake when closing the lid is useful for various purposes, such as allowing the computer to continue running tasks in the background, keeping remote connections active, or maintaining a continuous internet connection. This can be particularly helpful for users who need to perform tasks that require the computer to be constantly running, such as downloading large files or running automated scripts.
By preventing the Mac from going to sleep when the lid is closed, users can ensure that these tasks are completed without interruption. Additionally, keeping the Mac awake can also be useful for users who need to access their computer remotely, as it allows them to maintain a stable connection and access their files and applications even when the lid is closed.
How do I prevent my Mac from going to sleep when closing the lid?
To prevent a Mac from going to sleep when closing the lid, users can use a third-party application or a built-in feature called “caffeine.” Caffeine is a free application that can be downloaded from the internet and installed on the Mac. Once installed, users can activate caffeine by clicking on its icon in the menu bar and selecting the “caffeine” option.
Alternatively, users can also use the built-in “caffeine” feature in the Mac’s Energy Saver preferences. To access this feature, users need to go to System Preferences, click on Energy Saver, and then select the “Options” tab. From there, they can select the “Prevent computer from sleeping automatically when the display is off” checkbox to prevent the Mac from going to sleep when the lid is closed.
What are some third-party applications that can keep my Mac awake?
There are several third-party applications available that can keep a Mac awake when closing the lid. Some popular options include Caffeine, Amphetamine, and KeepingYouAwake. These applications work by simulating user activity or by overriding the Mac’s sleep settings, allowing users to keep their computer running even when the lid is closed.
These applications are often free or low-cost and can be easily downloaded and installed on the Mac. They also offer a range of features and customization options, allowing users to tailor their sleep settings to their specific needs. For example, some applications allow users to set a timer or schedule for when the Mac should stay awake, while others offer more advanced features such as customizable hotkeys and notifications.
Can I use the built-in Energy Saver preferences to keep my Mac awake?
Yes, users can use the built-in Energy Saver preferences to keep their Mac awake when closing the lid. To do this, users need to go to System Preferences, click on Energy Saver, and then select the “Options” tab. From there, they can select the “Prevent computer from sleeping automatically when the display is off” checkbox to prevent the Mac from going to sleep when the lid is closed.
However, it’s worth noting that this method may not work for all users, as it only prevents the Mac from sleeping when the display is off, but not when the lid is closed. Additionally, this method may also have some limitations, such as not being able to customize the sleep settings or set a timer for when the Mac should stay awake.
Will keeping my Mac awake when closing the lid affect its battery life?
Yes, keeping a Mac awake when closing the lid can affect its battery life. When the Mac is kept awake, it continues to consume power, which can drain the battery faster. This is because the computer’s processor, memory, and other components continue to run, even when the lid is closed.
However, the impact on battery life will depend on various factors, such as the type of tasks being performed, the brightness of the screen, and the overall system configuration. Users can minimize the impact on battery life by adjusting their sleep settings, turning off unnecessary features, and using power-saving modes.
Can I keep my Mac awake when closing the lid using Terminal commands?
Yes, users can keep their Mac awake when closing the lid using Terminal commands. One way to do this is by using the “caffeinate” command, which can be used to prevent the Mac from sleeping for a specified period of time. To use this command, users need to open the Terminal application, type in the command, and press Enter.
For example, the command “caffeinate -u -t 3600” will keep the Mac awake for 1 hour. Users can adjust the time period by changing the value of the “-t” option. Additionally, users can also use other Terminal commands, such as “pmset” or “osascript,” to customize their sleep settings and keep their Mac awake when closing the lid.
Are there any risks associated with keeping my Mac awake when closing the lid?
Yes, there are some risks associated with keeping a Mac awake when closing the lid. One of the main risks is overheating, as the computer’s components continue to run and generate heat even when the lid is closed. This can cause damage to the computer’s internal components, such as the processor, memory, and hard drive.
Additionally, keeping the Mac awake can also increase the risk of data loss or corruption, as the computer’s disk drives and other components continue to run and access data even when the lid is closed. Users can minimize these risks by ensuring proper airflow, using a cooling pad, and regularly backing up their data.
