Myth: You Need to Shut Down Your Computer Every Day

Modern Macs are designed for sleep, not to be constantly turned off. Sleep mode is efficient, safe, and convenient. Shutting down your Mac daily isn’t required for performance, and for many people, it’s just extra steps with little payoff.

That said, restarts still matter occasionally. If your Mac has been on for a long time, or after major updates, a restart can clear odd background behavior and refresh system processes.

So instead of turning off your Mac every night, restart it every week or every other week to refresh it, or if you notice it’s acting weird. 

With all of that said, you should only shut down your Mac if you know you’re not going to use it for a while, like before your vacation starts or something similar.
