Steps to do Before Factory Resetting your MacBook

For extra security, it’s crucial to back up all your files before restoring your MacBook to factory settings. That way you’ll be able to make sure that none of your personal details are compromised while your Mac is fully prepared for the new owner.

How to back up your Mac

The easiest way to create a backup of all your files before wiping a Mac is to copy your system with all its components. It is best to use Time Machine, a built-in MacOS utility that will do all the heavy lifting for you. Using this service means you won’t have to manually import the files to another physical drive. When you’re up and running on your new Mac, you can restore everything in a snap.


If you are planning to sell or give away your Mac, you may want to erase all your personal data so that the new user has no access to it.

Optional: Unpair your Bluetooth devices

If you are selling your Mac but plan to keep your wireless mouse or keyboard, it’s a good idea to unpair them from your old Mac. If you don’t unpair the devices and the new owner of your Mac gets in the Bluetooth range of your peripherals, it can cause inconvenience for both of you.


Your keyboard or mouse will try to connect to the old Mac and may  get disconnected from yours. This can result in the characters you type appear on the old Mac’s screen, which is not safe.


If you use iMac, Mac Mini, or Mac Pro, you will need to connect a wired keyboard to perform the steps.

  • Click the Apple logo and select System Preferences
  • Select the Bluetooth section
  • Hover your mouse over the name of the device to unpair and click the X button next to it


Resetting NVRAM (Non-Volatile Random Access Memory) will erase certain settings. These include your time zone, sound volume, recent kernel panic information, and configurations of your startup-disk and display. It will also restore security features to default.


To reset NVRAM, do the following:

  • Shut down your Mac: click the Apple logo and select Shut down
  • Look at your keyboard and find the following keys: Option + Command (⌘) + P + R. You will need to quickly press and hold these keys together in the next step, so you may want to remember their location
  • Turn back on your Mac and immediately press and hold Option + Command (⌘) + P + R
  • Hold the keys for about 20 seconds and then release them

Don’t forget, you can use these instructions if you’re selling your Mac or if you want to erase your startup disk to reinstall macOS. If you plan on keeping your Mac, you might be interested in our guide on how to make a bootable macOS installer before the factory reset process.
