Here is how to enable sleep mode on Mac: Way 1 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. 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. It is the same when Mac ‘wakes up.’ It takes longer because data is being copied from the drive to RAM.

It takes more time to enable this mode, but Mac does not consume any power during hibernation. The drive reserves an amount of memory approximately equal to the amount of RAM on the computer. The system consumes a minimum of energy because graphics and cooling are not working.Īll your documents, data, and running processes are copied from RAM to the drive in this mode. The power continues to be supplied to the device’s RAM. In this mode, all your unsaved documents, data, and running processes are stored in the RAM. Generally, on macOS, there are three types of sleep modes. Also, you can manually enable the sleep mode any time you need it. When you close your MacBook, it automatically goes to sleep. Sleep mode stops system processes on your Mac without needing to shut it down. 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.
