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.
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.
