How to reset your Mac to factory settings?

Before reselling or transferring your Mac, it is essential to delete your personal data. Good news, erasing data on a Mac is not that complicated, but before the “we erase everything and we start again”, you will have to go through 7 steps.

Follow our tutorial and your computer will find its youth of yesteryear!

1- Clone your Mac hard drive

Restoring a MacBook to factory settings will erase all your data stored on it. You must first transfer all data to another Mac, via a backup. Cloning your entire hard drive is the best option because it’s a perfect copy of your disk structure and its contents.

Carbon Copy Cloner and  SuperDuper are perfect programs to clone your hard drive (both have a free trial version, the options are paid for). To clone your drive, you will need an external hard drive and one of these programs. For this tutorial, we chose to use Carbon Copy Cloner (image above).

Launch the program then choose your hard drive said source and destination, and click Clone, bottom right of the screen.

Now you should be able to boot your Mac from your cloned external drive.

To do this, restart your Mac by holding down the Option key (between the crtl and Cmd key).

Using the arrow keys on your keyboard, select the external hard drive and press Enter.

This cloned drive can be cloned back to primary disk again if your goal is to restore your Mac or it can be used to access all the original files on your computer, in case of cleaning your internal drive.

2- Remove access authorization to iTunes

Before you separate from your Mac, remove the authorization to access your iTunes account. This means that your computer will no longer be associated with your iTunes account.

You will also need to remove the authorization from third-party programs such as Photoshop and disconnect from iCloud.

3- Disable FileVault

FileVault encrypts the files on your hard disk, so you do not have to leave it on because you are cleaning it. To do this, follow the steps below:

  1. Open System Preferences and click Security and Privacy.

  2. Select the FileVault tab.

  3. On the right side of the screen, you’ll see  Enable FileVault, if it’s grayed out, it’s not enabled. This is confirmed below by “FileVault is disabled for” Mac hd disk.
  4. To disable it, first, click on the padlock, bottom left, enter your password, and then disable FileVault.
