Using Mavericks and need to erase disk because it is sold. When I hold down option key, it shoes the CCC clone which is the temp boot drive and its recovery disk. It also show the Mac and recovery disk.

I have to install 10.6 on this and want to find out if I erase both of the10.9 disks, HD and Recovery and if so, what order?




iMac (27-inch Mid 2010), OS X Mavericks (10.9.2), two OWC external drives.

    You must repartition the drive in order to remove the Recovery HD. Do the following:


    What to do before selling or giving away your Mac


    Clean Install of Snow Leopard


    Be sure to make a backup first because the following procedure will erase

    the drive and everything on it.


         1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came

             with your computer.  Insert the disc into the optical drive and restart the computer.

             After the chime press and hold down the  "C" key.  Release the key when you see

             a small spinning gear appear below the dark gray Apple logo.


         2. After the installer loads select your language and click on the Continue

             button. When the menu bar appears select Disk Utility from the Utilities menu.

             After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive

             size.)  Click on the Partition tab in the DU main window.  Set the number of

             partitions to one (1) from the Partitions drop down menu, click on Options button

             and select GUID, click on OK, then set the format type to MacOS Extended

             (Journaled, if supported), then click on the Apply button.


         3. When the formatting has completed quit DU and return to the installer.  Proceed

             with the OS X installation and follow the directions included with the installer.


         4. When the installation has completed your computer will Restart into the Setup

             Assistant. Be sure you configure your initial admin account with the exact same

             username and password that you used on your old drive. After you finish Setup

             Assistant will complete the installation after which you will be running a fresh

             install of OS X.  You can now begin the update process by opening Software

             Update and installing all recommended updates to bring your installation current.


    Download and install Mac OS X 10.6.8 Update Combo v1.1.

    I have sold the iMac. Just need to format the disk after erase, if necessary, and install Snow Leopard from the disk and turn off when the Hello comes on...correct?

    You should shutdown the computer prior to when it reboots after the installation. You will have some time after the installation completes before the computer restarts. Just push in the Power button until the computer shuts down.
