How do I erase...

How do I erase all information on my imac. I am donating the computer to a charitable organization

Technician's Assistant: What Operating System (OS) are you running on your iMac?

I'm not sure what system it is. Where do I find that information?

Technician's Assistant: The Mac Technician will be able to walk you through that. Did the application come with an uninstaller, either on the installation disc or in the application's folder on your Mac?

No

Technician's Assistant: Anything else you want the Mac Expert to know before I connect you?

No i already joined. How do I get a refund when I'm finished?

Hello! Given the circumstances, I would recommend resetting your iMac entirely (erasing all files, reinstalling macOS, etc.). Here's how to do that:

Note: The software you have on your Mac is licensed to you, which means it doesn't get transferred to the new owner of your computer (except the operating system). In order to avoid complications with the new owner attempting to download and install software that is licensed by you, make sure to sign out of everything your personal information is connected to.

How to sign out of iTunes

  • Open iTunes on your Mac.
  • Click Account in the Menu bar on the left side of your screen.
  • Click on Sign Out.

    How to sign out of iMessage

  • Open Messages on your Mac.
  • Click Messages in the Menu bar at the top left corner of your screen.
  • Click Preferences from the drop-down menu.
  • Select your iMessage account.
  • Click on Sign Out.

    How to sign out of iCloud

  • Click on the Apple icon in the upper left corner of your Mac's screen.
  • Click System Preferences from the drop-down menu.
  • Click on iCloud.

  • Un-tick the box for Find My Mac.
  • Enter your system password ***** prompted.
  • Click on Sign Out.
  • Click Remove data from this Mac when prompted.

    Reformat your hard drive

    Once you've signed out of everything that might connect your old Mac to your personal information, you can erase everything on it by reformatting the hard drive.

  • Turn on or restart your Mac.
  • Hold down Command and R at the same time right after you restart your Mac. Keep holding down the keys until your Mac finishes loading and you see the macOS Utilities window.
  • Select Disk Utility.
  • Click on Continue.

  • Select your Startup disk (it is probably named "Macintosh HD" or something similar).
  • Click on Erase from the buttons at the top of the Disk Utility window.

  • Select Mac OS Extended (Journaled) from the drop-down menu next to Format.
  • Select GUID Partition Map from the drop-down menu next to Scheme (where applicable - not ever Mac has this).
  • Click Erase.
  • After the process is complete, select Quit Disk Utility from the Disk Utility drop-down menu in the upper left corner of the screen.​



    Reinstall a clean Mac operating system

    After you reformat your hard drive it will be ready for a clean installation of the operating system. You should already be in the Utilities window after erasing your Mac. If not, restart your computer and hold down Command and R at the same time until you see the Apple logo.

    Note: Make sure your Mac is connected to the internet in order to verify the software. You'll be asked to do so during the installation process.

  • Turn on or restart your Mac.
  • Hold down Command and R at the same time right after you restart your Mac. Keep holding down the keys until your Mac finishes loading and you see the macOS Utilities window.
  • Click on Reinstall macOS (or Reinstall OS X where applicable) to reinstall the operating system that came with your Mac.
  • Click on Continue.
  • Select your hard drive ("Machintoch HD" or something similar), when asked to select your disk.
  • Click on Install to install the operating system that came with your Mac. Your Mac will restart after the installation is complete.
  • Hold down Command and Q after the installation is complete. Do not follow the setup instructions. Leave that part for the new owner. 8 Click Shut Down to shut down your Mac.

    Your Mac is now clean and ready for a new owner. :-)

One Happy CustomerNew York

I am very happy with my very fast response. Eric is very knowledgeable in the subject area. Thank you!

RPAustin, TX

Hi John, Thank you for your expertise and, more important, for your kindness because they make me, almost, look forward to my next computer problem. After the next problem comes, I'll be delighted to correspond again with you. I'm told that I excel at programing. But system administration has never been one of my talents. So it's great to have an expert to rely on when the computer decides to stump me. God bless, Bill
