Mac® computers are prized for their superior energy efficiency, speed, and memory management. Like any other machine, though, they need periodic rest. Specifically, they can be put to “sleep” or shut down entirely to halt activity and maintain performance. Whether you’re trying to extend the life of an older model or concerned about power usage, it's helpful to know the differences between sleep mode and shutdown—and how often your Apple® product may need them. 

What Happens When You Shut Down a Mac?

When you turn the computer off, all system processes are closed, and all power is completely stopped until the system is powered on again. In terms of efficiency, shutting down is the best way to save energy and give the system a break. During shutdown, cache files and RAM (random access memory) are cleared, allowing the system to run faster upon reboot. 

Shutting down is also sometimes necessary to install important system updates—such as those that maintain cybersecurity or improve processing speed. Otherwise, manual updates will be necessary. Since shutting the computer down can take time to close out programs and reboot the system, it can present a minor inconvenience to those who frequently need to use their Mac right away.  

What Happens When a Mac Sleeps?

Sleep mode offers a more flexible option for Apple product users to save energy in a more convenient than shutting down. Most computer processes and parts are powered down in sleep mode so that they don’t use energy. 

The RAM, however, will continue to draw energy to keep active programs and files just as you left them. Rather than having to go through a lengthy reboot, you can simply move the mouse or touch a key to “wake” the Mac back up. 

Which Should You Choose? 

When you're done using your system, putting it in sleep mode is usually more than enough to preserve the system and minimize energy use. However, if you don’t plan on using the device for a while or are due for a system refresh, shutting down is recommended. 

If you prefer to put your computer in sleep mode, you should still make it a practice to shut down the system when updates need to be installed or excessive processes are slowing down the speed. Generally, the average daily user can choose shutdown once per week and rely on sleep mode the rest of the time.
