This will protect your data from being accessed by anyone else and provide the new user with a like-new experience on your old Mac orMacBooklaptop. It will also un-sync services and software connected to your old Mac, preventing any issues in the future with accessing them.

The M-series processors brought about a new way to factory reset your Mac, so if you’ve never reset a Mac, or haven’t reset a Mac since the M-series chips came out, this guide is for you. If you’re using a Mac with macOS Monterey or later, and have a Mac with an M1, M2, orM3 processor, the steps for resetting your Mac are easier than they were before.

The first step to wiping a Mac

You already know… back it all up

It should always be noted that doing a factory reset means deleting everything stored on your Mac. While you may think you can just rest assured with your automatic iCloud saves, think again. An iCloud back-up will back-up nearly everything on your Mac (or iPhone, iPad, Watch). However, it will not treat non-Apple software the same way. That lengthy proposal you are working on with a word editor? If it’s not pages, it’s probably not backed up to iCloud.

Fortunately, it’s easy to back up a Mac, so long as you have anexternal drive. With an external drive, you can use Apple’s Time Machine program to back up everything on your Mac to your trusty external drive, and go on with your day. It’s easy to use, and there’s a step-by-step guided backup tool that will help you connect to your external drive and create the backup.
