Your Mac goes to sleep so fast because macOS is designed for maximum power efficiency. By default, when your Mac is inactive for a certain amount of time, it automatically enters sleep mode to conserve energy and prolong battery life. This helps ensure that your Mac runs as efficiently as possible and that you get the most out of its battery life. You can adjust the energy settings on your Mac if you’d like, but remember that this may reduce its power efficiency.
