When a Mac is not in use, most generally want the device to go into sleep mode. During sleep mode, it helps save battery life, reduce energy consumption and increase the overall longevity of your device. Besides, the MacOS allows you to specify the time frame on how long the display stays on during a period of inactivity before it turns off to reduce energy consumption and increase battery life.
But oftentimes, some users do not want their device to sleep especially in cases when preparing a Keynote presentation or when allowing someone else to use the device. This passage, therefore, offers some efficient methods to help them prevent Mac from sleeping.

What Is the Purpose of Sleep Mode in Mac?
The Sleep mode on Mac computers helps save energy but can quickly turn back on for quite a while. Even today, most users still question what happens to a Mac when it sleeps. Generally, there are various Sleep modes supported by Mac. Since 2005, Apple has provided 3 basic modes of Sleep.
- With this mode of Sleep, the RAM of your Mac is left powered on while asleep. This enables the device to wake up quickly since there is no need to load anything from the hard drive. This mode is the default sleep for desktop Macs.
- In this mode, the RAM data are added to the startup drive before the device enters the sleep mode. When sleeping, power is removed from the RAM. When you wake the device up, the startup drive must initially write data back to the RAM in which the wake time is a bit slower. Take note that this is the default sleep mode for portable Macs released before 2005.
- Safe sleep. The RAM data are added to the startup drive before the device goes to sleep, but the RAM is still functional as the device sleeps. The wake time is quick since the RAM still contains the pertinent data. Writing the content of the RAM to the startup drive is a precautionary measure. In case an issue occurs such as battery failure, your data can still be recovered.
