What is Mac’s sleep mode?
Mac’s sleep mode is an option on macOS that turns off the display, puts the processor into energy-saving mode, and stops the hard drive and background processes. Sleep mode stops system processes on your Mac without needing to shut it down. When you close your MacBook, it automatically goes to sleep. Also, you can manually enable the sleep mode any time you need it.
Generally, on macOS, there are three types of sleep modes. Each of them has distinctive features:
- Sleep
In this mode, all your unsaved documents, data, and running processes are stored in the RAM. The power continues to be supplied to the device’s RAM. The system consumes a minimum of energy because graphics and cooling are not working. - Hibernation
All your documents, data, and running processes are copied from RAM to the drive in this mode. The drive reserves an amount of memory approximately equal to the amount of RAM on the computer. It takes more time to enable this mode, but Mac does not consume any power during hibernation. It is the same when Mac ‘wakes up.’ It takes longer because data is being copied from the drive to RAM. - Safe sleep
In this mode, data from RAM is copied to the drive, but your Mac itself is not powered off, so working documents are stored both in RAM and on your disk. When your Mac ‘wakes up’, it takes the same time as in normal sleep mode, but it creates a backup from RAM in case of a power outage or a complete discharge of the battery.
Here is how to enable sleep mode on Mac:
Way 1
- Go to the Apple Menu.
- Click Sleep.
Way 2
If you have a MacBook, close the lid, and your system will go to sleep in a few seconds. Once you open the lid, your Mac wakes up.
Way 3

- Control + Shift (⇧) + Power button
- Command (⌘) + Option (⌥) + Power button
