How to Wipe an iMac: A Step-by-Step Guide

Wiping an iMac can be a daunting task, especially if you're not familiar with the process. However, with these simple steps, you'll be able to erase all data and settings on your device, returning it to its factory state.

Before you begin, make sure you have administrator privileges on the Mac. If prompted, select the user account and enter the administrator password.

If you're unable to boot into the regular macOS recovery screen, don't worry. You can use Fallback Recovery OS instead. This will allow you to access the recovery mode and continue with the wiping process.

To boot your iMac in macOS Recovery Mode, restart your device and hold down the power button until you see 'Loading startup options' appear on the screen. Release the button and select the 'Recovery HD' option from the menu that appears.

Once you're in Recovery Mode, you'll need to turn off FileVault if it's enabled. This will prevent any data encryption from interfering with the wiping process.

Now, follow these steps to factory reset your Mac running macOS Big Sur or earlier:

1. Restart your iMac and immediately hold down the Command + R keys on your keyboard.

2. Release the keys when you see the Apple logo appear on the screen.

3. Select the language you prefer and click 'Continue.'

4. Click on 'Disk Utility' and select your startup disk from the list of available volumes.

5. Click the 'Erase' button at the top of the Disk Utility window and choose 'Quick Erase' or 'Security Erase,' depending on your needs.

6. Wait for the erasing process to complete. This may take several minutes, depending on the size of your hard drive.

Once the wiping process is complete, you'll be prompted to restart your iMac. After restarting, follow the setup assistant to set up your device and select a Wi-Fi network to activate it. Finally, click 'Restart' to finish the setup process.

Note that the new erase process in macOS Monterey handles everything for you, including erasing all settings, media, apps, and data for all accounts and volumes on the drive. This means that any iCloud data, Apple ID information, Touch ID fingerprints, Bluetooth devices, Apple Wallet data, and more will be completely erased.

By following these simple steps, you'll be able to wipe your iMac and start fresh with a clean slate.
