Why does my Mac go to sleep?

When your iMac or MacBook is not in use for a minute or two, the display dims slightly. The screen saver kicks in soon and stays on for the next ten minutes. After that, the screen goes completely black. This is called the sleep mode! This inactive state of the Mac shuts down all visible Mac activities but keeps essential processes running. So, it's different from a complete shutdown on a PC. For instance, your Mac can check your email app in the background while it's in sleep mode. As soon as you press any button or touch the screen, your MacBook Air/Pro wakes up promptly.

You surely know what Sleep mode means on a Mac. But the question is, why does your Mac go to sleep in the first place! Apple designs macOS to be as power-efficient as possible; hence, by default, your Mac tries to conserve energy to prolong battery life. As a result, it automatically goes to sleep when you don't use it for a while.
