When to Restart MacBook Air
We recommend restarting your MacBook Air regularly because it's suitable for the overall operation of your laptop. Each restart refreshes your laptop's active memory (but don't worry; there's no data loss), and it's also when new software updates get installed. Restarting a MacBook Air can also help fix problems like slow performance, trouble opening apps, generally buggy-ness, or freeze-ups. In those situations, a restart will often solve most problems.
What Makes a Restart, Factory Reset, and Power Down Different
Restarting a MacBook Air isn't the same thing as powering it down or a factory reset.A restart resets your operating system and cleans out the memory that programs run in. There's no data loss with a restart, but your MacBook Air will run better afterward.Powering down a MacBook Air turns it off and stops programs from running, and saves battery power.A factory reset takes your laptop back to its original state, just like when you first got it. It deletes all of your apps and data, erases the hard drive, and re-installs the macOS. You should only factory reset your MacBook Air if you're selling the laptop, sending it in for service, or trying some last-ditch troubleshooting.
