While the sleep function on your Mac is a practical and valuable feature that promotes and protects your MacBook's health, there are times when you might want to turn off sleep mode and keep it running as normal. For example, if you're trying to watch a long movie and your display keeps turning off, or when you're trying to download large files, and they keep failing because sleep mode suddenly activates. There are several ways to keep your Mac awake, including using apps like Amphetamine, KeepingYouAwake, Caffeine, and One Switch, or by adjusting your System Settings or Terminal.

Caffeine
Caffeine is a simple app that prevents your Mac from going to sleep with one click. It is inspired by Caffeine from Lighthead Software.

Adjust sleep settings in System Preferences
Sleep mode is a valuable feature that helps your Mac conserve energy, aids battery life, and protects its performance over time. However, there may be times when you need to keep your Mac processing without sleeping. Here are the steps to adjust sleep settings in System Preferences:
Step 1: Access System Preferences
Click on the Apple menu icon, usually located on the top left of your toolbar. Then, select 'System Preferences'.
Step 2: Navigate to Energy Saver
Once in System Preferences, look for 'Energy Saver'. Depending on your macOS version, this may be located under different names, such as 'Lock Screen / Battery / Energy Saver'. If you're using an older version of macOS, you might need to adjust these settings under ''Battery' or 'Power Adapter'.
Step 3: Adjust Sleep Settings
Within the Energy Saver settings, you'll find options to customize your Mac's sleep behaviour. Here are some key settings you can adjust:
- Computer Sleep: Use the slider or drop-down menus to set the amount of inactivity time before your Mac automatically enters sleep mode. You can also select ''Prevent automatic sleeping'' to keep your Mac awake indefinitely.
- Display Sleep: Similarly, adjust the slider or drop-down menus to determine when your display turns off or enters sleep mode.
- Power Nap: Enable this feature to allow your Mac to update and check for emails, calendar events, and iCloud updates while it's asleep.
- Wake for Network Access: Turn this on to allow your Mac to wake briefly so that users can access shared services.
- Put Hard Disks to Sleep: Enable this setting to put your hard disks to sleep when possible, conserving even more energy.
Step 4: Save Changes
Once you've made your desired adjustments, click 'Done' or 'Save' to apply the new sleep settings.
By following these steps, you can customize your Mac's sleep behaviour to suit your specific needs, ensuring that it stays awake when necessary without sacrificing energy efficiency.

Clean your RAM using MacKeeper's Memory Cleaner
While Apple's sleep function is a practical and valuable feature that promotes and protects your MacBook's health, it can sometimes be inconvenient. For instance, when you are downloading large files or watching a long movie, and your display keeps turning off. In such cases, you can prevent your Mac from sleeping by adjusting your settings or using apps.
One such app is MacKeeper, a RAM Memory Cleaner that helps free up RAM in a click, plus safely quit processes to help speed up your Mac. MacKeeper's Safe Cleanup feature removes junk files stored on your hard drive, and its Memory Cleaner frees up resources your Mac uses to run apps and launch processes. It is easy to use, with a quick install, and then you are guided through the process of scanning and protecting your Mac. You can grab a free test drive of the RAM cleaner tool for Mac, and the first cleanup is free. For another memory cleanup, you will need a MacKeeper license.
Another option is CleanMyMac, which is great at clearing memory on a Mac in a few clicks and is also good for managing the overall performance of your laptop. It has a malware removal feature and a system optimization feature. Memory Clean 3 is another easy and straightforward app that is low-cost and perfect for restoring your Mac's speed on a budget.
If you would prefer to adjust your settings, you can do so in the following ways:
- Go to System Preferences, and click Battery in the sidebar. Click Options, then enable the "Prevent the computer from automatically going to sleep when the display is off" option.
- Go to System Preferences > Energy Saver. Select “Prevent your Mac from automatically sleeping when the display is off.”
- Go to the Apple menu > System Settings. Choose Battery in the sidebar. Then click Options. Enable "Prevent automatic sleeping on power adapter when the display is off".
- Open Terminal and enter the command "caffeinate -d". If you want to keep your laptop awake for a certain amount of time, type "caffeinate -t X", where X is the number of seconds.

Prevent automatic sleeping when the display is off
To prevent your Mac from automatically sleeping when the display is off, you can adjust your System Settings or Preferences. Here's how:
MacOS Ventura and Sonoma:
- Click the Apple logo in the upper-left corner of the screen.
- Click "System Settings".
- Scroll down the sidebar and click "Lock Screen".
- Find the line "Turn display off on power adapter when inactive" in the right panel.
- Click on the drop-down next to it and set the sleep time to your preference or Never.

- Click the Apple icon in the upper-left corner of the screen.
- Choose "System Preferences".
- Click "Energy Saver".
- Find the line "Prevent your Mac from automatically sleeping when the display is off" and select the checkbox.
- Confirm your selection.
Alternatively, you can use the Terminal app to make temporary changes to your Mac's sleep settings. Here's how:
- Open the Terminal app by typing "Terminal" in the search bar in Launchpad.

Use Terminal to make temporary changes to sleep settings
If you want to make temporary changes to the sleep settings, you can do this through the Terminal. The changes will be active as long as the Terminal window is open.
To open Terminal, go to Finder > Applications > Utilities, or type “Terminal” in the search bar in Launchpad.
Enter the following command in the Terminal: caffeinate -d. If you want to keep your laptop awake for a certain amount of time, type caffeinate -t X, where X is the number of seconds.
For macOS 13, Ventura, use the command sudo pmset sleep 0 to change the Settings > Displays > Advanced > Energy > Prevent automatic sleeping when the display is off, to enabled. Setting it to anything other than 0 will disable that setting.
Another option is pmset. Use the command pmset noidle to prevent sleep as long as pmset is running. However, this requires a separate Terminal window with pmset running in it.
For Mountain Lion, you can use the caffeinate command. If no assertion flags are specified, caffeinate creates an assertion to prevent idle sleep. If a utility is specified, caffeinate creates the assertions on the utility's behalf, and those assertions will persist for the duration of the utility's execution. Otherwise, caffeinate creates the assertions directly, and those assertions will persist until caffeinate exits.
You can also use the InsomniaX.app to prevent your Mac from sleeping, although it does not appear to have a working command-line version.
