Why Do You Need to Factory Reset Your Mac?

The major reason anyone would want to reset their Mac is if they are ready to sell it or swap it with another.

Therefore, factory resetting your Mac is the best way to prepare it for a new owner.

Also, if your Mac starts to misbehave, you might need to factory reset it to freshen it up. Factory resetting your Mac reinstalls a clean and new version of macOS. This can give you a feeling of operating a new Mac.

7 Things You Need to Do Before Erasing Your Mac

If you have decided to wipe your Mac, here is a list of things to do before proceeding:

01 Make a backup

Back up your data before restoring your device to factory settings by disabling some features and services, wiping your Mac, and reinstalling macOS.

Ensure that you have a current backup of your critical files. You can manually build a backup on an external hard drive or iCloud.

02 Sign out of iTunes in macOS Mojave or earlier

Open iTunes if you're running macOS Mojave or older. Select Account > Authorizations > Deauthorize This Computer from the menu bar at the top of the screen or iTunes window. Then input your Apple ID and password before clicking Deauthorize.

03 Sign out of iCloud

If you're running macOS Mojave or earlier, go to the Apple menu > System Preferences, then iCloud, then finally Sign Out.

You will be prompted to maintain a copy of your iCloud data on this Mac. Because you will be wiping your Mac later, you may choose Keep a Copy. Your iCloud data stays in iCloud and on any other devices that are signed in to iCloud with your Apple ID.

04 Sign out of iMessage

To sign out of iMessage, launch the Messages app, then select Messages > Preferences from the menu bar. Then, select iMessage, and last, select Sign Out.

05 Reset NVRAM

Shut off your Mac, then switch it on and instantly hit and hold the Option, Command, P, and R keys together. After around 20 seconds, release the keys. This will erase all user settings from memory and restore any previously changed security features.

06 Unpair Bluetooth devices you intend to retain (optional)

If your Mac has been connected with a Bluetooth keyboard, mouse, trackpad, or other Bluetooth device that you intend to maintain, you can unpair it. When the Mac and Bluetooth device have different owners but stay within Bluetooth range of each other, this optional step avoids any inadvertent input or device connection.

To finish the following steps in this article, you must connect in a USB keyboard and mouse if you are unpairing Bluetooth input devices from a desktop computer, such as an iMac, Mac mini, or Mac Pro.

To unpair a Bluetooth device, go to the Apple menu > System Preferences > Bluetooth. Place your cursor over the device you wish to unpair, then click the remove (x) button next to its name.

07 Erase your hard drive and reinstall macOS

Erasing your hard drive and reinstalling macOS is the best approach to return your Mac to factory settings.

Following the completion of macOS installation, the Mac will restart and display a setup assistance prompting you to select a nation or region. Don't continue the setup procedure if you want to keep the Mac in its original condition. To shut off the Mac, instead, use Command-Q. The setup assistant will walk the new owner through the setup procedure when they switch on the Mac.
