We are assuming you already copied all your data to an external backup, or to your new Mac, because the following steps will really erase your disk.

1. Restart your Mac and hold down the following button combination:
   Option + Command + R
2. The computer will begin to boot into the MacOS Recovery mode. The macOS Utilities menu will appear after a few minutes.
3. Open Disk Utility to begin the disk erasing process. Select the Internal storage disk in the left-hand menu. It will be called Apple SSD on recent Macs.
4. Click on the Erase button at the top of the Disk Utility, this brings up our disk formatting options. MacintoshHD is the default disk name in macOS, disk format required is Mac OS Extended (Journaled), and the Scheme is GUID Partition Map.
5. After erasing the disk you are ready to move on to the operating system installation. An Internet connection is required to download a copy of macOS from Apple. Connect to a Wi-Fi network by clicking on the Wi-Fi icon at the top right of the menu bar.
6. Now that you are connected to the Internet, click Reinstall macOS in the macOS Utilities menu.
7. Follow the install prompts in the installation guide, read and agree the terms and conditions.

10. Once the installation is complete, the Mac will restart and display the factory fresh Welcome screen. At this point your Mac is ready to be handed over to a new owner.
11. Unless the new owner is right there already with you, you will probably want to power down the Mac. Press the power button and a dialog box will appear that allows you to shut down.
12. Give your beloved Mac a good physical wipe down with some dry cloths, and wave it goodbye.
