It is, in essence, a small (650MB) partition on your Mac’s internal hard drive (traditional magnetic HDD or solid state disc SSD) that is ‘hidden’ and reserved for common.

This guide will walk you though erasing your disk, and re-installing a fresh copy of macOS

Why you need to erase your hard drive/SSD

Jun 26, 2020  But if the latest version of Mac OS uses seven passes to empty the trash, while Permanent Eraser uses 35, logic would dictate that it SHOULD take at least five times as long to erase. Mode 3: Wipe Free Disk Space. Select mode “Wipe Free Space” – select the partition or gadget – click on “Wipe Now” catch to wipe the unused space of the chosen hard drive/gadget. The PhoneClean Mac Data Erase software is basic yet adaptable programming that erases your whole information without rupturing your. As of OS 10.3, Macs have had the 'Secure Empty Trash' option in the Finder menu, which provides a pretty good secure delete option. However, if you're serious about securely removing files and you.

When you empty your trash bin on your Mac, the files are not really erased. Instead, the reference to the file is removed from the file system (which keeps a list of all the files on your computer), so the computer is able to write new information in the same physical area when space is needed. This is much quicker than rewriting that disk space with blank data, and it also gives you a chance to recover accidentally deleted files with handy recovery software.

Erasing your storage drive and performing a fresh install using macOS Recovery

You will need:

  • A Wi-Fi network with an active Internet connection
  • Time. Budget at least an hour for this process, slower Internet connections and older hardware will take longer.

Let’s begin!

Steps may vary with different version of macOS, and hardware configurations but the general idea is the same. We are erasing a 2014 MacBook Air running MacOS 10.12 Sierra, but the steps will be similar with any recent Mac. 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.
  8. When prompted to select an install disk, select the disk that we had just erased. There will only be one option in most cases.
  9. The computer will download a copy of macOS from Apple, and install it on the disk. The system download is several Gigabytes in size, therefore the length of time is determined by the speed of your internet connection.
  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.
