Today we will be discussing how to wipe a Mac. Whether you’re looking to sell your Mac or simply want to start fresh, wiping your device is an essential step. In this tutorial, we will guide you through the process of securely erasing your Mac’s data and restoring it to its factory settings.

Before You Begin

Before you proceed with wiping your Mac, it’s important to back up all your important files and data. This ensures that you don’t lose any valuable information during the process. You can use Time Machine or any other reliable backup solution to create a backup of your Mac.

Step 1: Sign Out of iCloud

The first step is to sign out of iCloud on your Mac. Open the Apple menu from the top-left corner of the screen and select “System Preferences”.

In the System Preferences window, click on “Apple ID” and then select “Overview” from the sidebar. Finally, click on “Sign Out” at the bottom-left corner.

Step 2: Deauthorize Your Computer

If you have authorized your Mac for services like iTunes, make sure to deauthorize it before wiping. Open iTunes and click on “Account” in the menu bar.

From the drop-down menu, select “Authorizations” and then click on “Deauthorize This Computer”. Enter your Apple ID credentials when prompted.

Step 3: Erase Your Data

To securely erase your data, restart your Mac and hold down the Command + R keys until you see the Apple logo or a spinning globe. This will boot your Mac into Recovery Mode. In Recovery Mode, select “Disk Utility” and click on “Continue”.

In Disk Utility, select your startup disk from the left sidebar (usually named “Macintosh HD”) and click on the “Erase” button at the top. Choose a suitable format (such as APFS or Mac OS Extended) and enter a name for your disk. Click on “Erase” to start the erasing process.

Step 4: Reinstall macOS

After erasing your data, close Disk Utility and select “Reinstall macOS” from the macOS Utilities window. Follow the on-screen instructions to reinstall a fresh copy of macOS on your Mac. This will restore your Mac to its factory settings.

Step 5: Restore Your Data

Once you have successfully reinstalled macOS, you can restore your backed-up data using Time Machine or other backup solutions. Connect your external storage device or access your backup files from the cloud, and follow the prompts to restore your files and settings.


Congratulations! You have successfully wiped your Mac and restored it to its factory settings. By following these steps, you can ensure that all your personal data is securely erased before selling or giving away your Mac.

Remember, wiping a Mac is an irreversible process, so make sure to back up all important files before proceeding. Take care during each step of the process, and always double-check before erasing any data.
