I want to wipe my computer to zeros but cannot locate the original Snow Leopard disc.  Any other way of doing this without the disc? I am prepping it for sale. Except now I have to sell it without the start up disc. That may be a problem and I'll deal when that time comes but for now... I just want to wipe it clean.  Suggestions please.. 

 

OS X version 10.8.5.  Originally had Snow Leopard on it.  It now has Mountain Lion.

    Nope. You need an install disc, preferably those that came with your computer. You can purchase replacements from Apple:

     

    Apple Store Customer Service at 1-800-676-2775 or visit online Help for more information.

     

    To contact product and tech support: Apple - Support - Contact Apple Support.

     

    You can purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.

     

     

    After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.

    Leave it at SL.  Install SL, give the new owner the disks.  Let the new owner take it from there.

    You cannot install Mountain Lion or Lion as your copies are not transferrable.

     

    See the following:

     

    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. Use Boot Camp Assistant to remove a Windows partition, if there be one.

              6. 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.

     

         C. See What to do before selling or giving away your Mac

     

     

    *If your computer came with Lion or Mountain Lion pre-installed then you are entitled to transfer your license once. You must remove the computer from your list of registered hardware. If you purchased Lion or Mountain Lion from the App Store then you cannot transfer your license to another party. In this case 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. See Terms and Conditions if you need to transfer an Extended Warranty that is still in effect (Transfer of Plan.)

    Yes, by providing the Snow Leopard disc with the computer.
