Hello,

 

I am trying to restore my mac mini to factory settings.

I was able to access the disk utility but am not sure which disk I should select before erasing.

 

Options in Utilities pane:

 

500.11 GB Toshiba MK506GSXF Media

     Macintosh HD

 

Disc 1

     Mac OS X Base System

 

I want to reformat disk so that no existing data is retrievable AND want to be able to resintall the operating system thereby restoring to factory settings.

 

Your help is much appreciated!

    You'll select the:

     

    500.11 GB Toshiba MK506GSXF Media

         Macintosh HD

    Follow these instructions step by step to prepare a Mac for sale:

     

    Step One - Back up your data:

     

           A. If you have any Virtual PCs shut them down. They cannot be in their "fast saved" state. They must be shut down from inside Windows.

           B. Clone to an external drive using using Carbon Copy Cloner.

     

              1. Open Carbon Copy Cloner.

              2. Select the Source volume from the Select a source drop down menu on the left side.

              3. Select the Destination volume from the Select a destination drop down menu on the right

                  side.

              4. Click on the Clone button. If you are prompted about creating a clone of the Recovery HD be

                  sure to opt for that.

     

                   Destination means a freshly erased external backup drive. Source means the internal

                   startup drive.

     

    Step Two - Prepare the machine for the new buyer:

     

              1. De-authorize the computer in iTunes! De-authorize both iTunes and Audible accounts.

              2, Remove any Open Firmware passwords or Firmware passwords.

              3. Turn the brightness full up and volume nearly so.

              4. Turn off File Vault, if enabled.

              5. Disable iCloud, if enabled: See What to do with iCloud before selling your computer.

     

    Step Three - Install a fresh OS:

     

         A. Snow Leopard and earlier versions of OS X

     

              1. Insert the original OS X install CD/DVD that came with your computer.

              2. Restart the computer while holding down the C key to boot from the CD/DVD.

              3. Select Disk Utility from the Utilities menu; repartition and reformat the internal hard drive.

                  Optionally, click on the Security button and set the Zero Data option to one-pass.

              4. Install OS X.

              5. Upon completion DO NOT restart the computer.

              6. Shutdown the computer.

     

         B. Lion and Mountain Lion (if pre-installed on the computer at purchase*)

     

             Note: You will need an active Internet connection. I suggest using Ethernet if possible because

                       it is three times faster than wireless.

     

              1. Restart the computer while holding down the COMMAND and R keys until the Mac OS X

                  Utilities window appears.

              2. Select Disk Utility from the Mac OS X Utilities window and click on the Continue button.

              3. After DU loads select your startup volume (usually Macintosh HD) from the left side list. Click

                  on the Erase tab in the DU main window.

              4. Set the format type to Mac OS Extended (Journaled.) Optionally, click on the Security button

                  and set the Zero Data option to one-pass.

              5. Click on the Erase button and wait until the process has completed.

              6. Quit DU and return to the Mac OS X Utilities window.

              7. Select Reinstall Lion/Mountain Lion and click on the Install button.

              8. Upon completion shutdown the computer.

     

    *If your computer came with Lion or Mountain Lion pre-installed then you are entitled to transfer your license once. If you purchased Lion or Mountain Lion from the App Store then you cannot transfer your license to another party. In the case of the latter you should install the original version of OS X that came with your computer. You need to repartition the hard drive as well as reformat it; this will assure that the Recovery HD partition is removed. See Step Three above. You may verify these requirements by reviewing your OS X Software License.

    CollinFarmer,

     

    500.11 GB Toshiba MK506GSXF Media

    Macintosh HD

     

    Each of these are selectable options, should I select 500.11 GB.... or Macintosh HD?

     

    Thanks!

  • Kappy Level 10 Level 10 (237,445 points)

    If you are repartitioning choose the top one. If you are erasing a volume choose Macintosh HD.

     

    Note that you cannot erase a startup volume. To erase it you must boot from an installer DVD or some other bootable volume. Please see my previous post.

    Forgive my cluelessness, but I'm not sure if I'm repartioning or not.  I just want to restore the mini back to factory settings (mini in it's condition out of the box).  That said, which one should I choose?  I appreciate your help!

  • Kappy Level 10 Level 10 (237,445 points)

    Provide this information, please:

     

    What version of OS X do you now have installed?

    Do you have installer DVDs? If so, for what OS X version?

    Are you doing this to sell or give away the computer?

  • TCS77 Level 1 Level 1 (0 points)

    Mac OS X Lion Version 10.7.5

    I do not have installer DVDs (none came in box)

    I am doing this to sell the computer.

  • TCS77 Level 1 Level 1 (0 points)

    With regard to data, I've barely used the computer and am not concerned about saving any files I've added since purchase.

  • Kappy Level 10 Level 10 (237,445 points)

    You can follow this procedure, then.

     

         B. Lion and Mountain Lion (if pre-installed on the computer at purchase*)

                       it is three times faster than wireless.

                  Utilities window appears.

              2. Select Disk Utility from the Mac OS X Utilities window and click on the Continue button.

              3. After DU loads select your startup volume (usually Macintosh HD) from the left side list. Click

    Thanks Kappy!

     

    I'm following the steps above.

    Just to confirm, I don't need to perform the following steps:

     

    Step Two - Prepare the machine for the new buyer:

     

    1. De-authorize the computer in iTunes! De-authorize both iTunes and Audible accounts.

    2, Remove any Open Firmware passwords or Firmware passwords.

    Correct.
