    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. You can then access the App Store where you can freely download the Maverick installer. Your computer must meet the requirements:


    OS X Mavericks- System Requirements

     

          Macs that can be upgraded to OS X Mavericks

     

             1. iMac (Mid 2007 or newer) - Model Identifier 7,1 or later

             2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) - Model Identifier 5,1 or later

             3. MacBook Pro (Mid/Late 2007 or newer) - Model Identifier 3,1 or later

             4. MacBook Air (Late 2008 or newer) - Model Identifier 2,1 or later

             5. Mac mini (Early 2009 or newer) - Model Identifier 3,1 or later

             6. Mac Pro (Early 2008 or newer) - Model Identifier 3,1 or later

             7. Xserve (Early 2009) - Model Identifier 3,1 or later

     

    To find the model identifier open System Profiler in the Utilities folder. It's displayed in the panel on the right.

     

         Are my applications compatible?

    That requires that you erase your disk, but as your Mac does not have Internet Recovery functionality how do you plan on installing Mavericks, do you have an installer? that you can boot from, what is on your iMac at the moment?

    Do you have the original discs that came with your computer? If not, then you will need a Snow Leopard DVD or you cannot do a clean install of Mavericks.

     

    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 Mavericks.

    After all of this discussion what do you really hope to gain with the clean install anyway?

     

    It has been my experience that they are usually nothing but a waste of time.

    Before embarking on a major OS upgrade, it would be wise, advisable and very prudent if you backup your current system to an external connected and Mac formatted Flash drive OR externally connected USB, Thunderbolt or FireWire 800, Mac formatted hard drive. Then, use either OS X Time Machine app to backup your entire system to the external drive OR purchase, install and use a data cloning app, like CarbonCopyCloner or SuperDuper, to make an exact and bootable copy (clone) of your entire Mac's internal hard drive. This step is really needed in case something goes wrong with the install of the new OS or you simply do not like the new OS, you have a very easy way/procedure to return your Mac to its former working state

     

    Then, determine if your Mac meets ALL minimum system install requirements.

    To install Mavericks, you need one of these Macs:

     

    iMac (Mid-2007 or later)

    MacBook (13-inch Aluminum, Late 2008), (13-inch, Early 2009 or later)

    MacBook Pro (13-inch, Mid-2009 or later),

    MacBook Pro (15-inch or 17-inch, Mid/Late 2007 or later)

    MacBook Air (Late 2008 or later)

    Mac mini (Early 2009 or later)

    Mac Pro (Early 2008 or later)

    Xserve (Early 2009)

    Your Mac also needs:

    OS X Mountain Lion, Lion, or Snow Leopard v10.6.8 already installed

    2 GB or more of memory (I strongly advise, at least, 4 GBs of RAM or more)

    8 GB or more of available space

     

     

    Next,

    If you run any older Mac software from the earlier PowerPC Macs, then none of this software will work with the newer OS X versions (10.7 and onward). OS X Snow Leopard had a magical and invisible PowerPC emulation application, called Rosetta, that worked seamlessly in the background that still allowed older PowerPC coded software to still operate in a Intel CPU Mac.

    The use of Rosetta ended with OS X Snow Leopard as the Rosetta application was licensed to Apple, from a software company called Transitive, which got bought out, I believe, by IBM and Appe  could no longer secure their rights to continue to use Rosetta in later versions of OS X.

     

    So, you would need to check to see if you have software on your Mac that maybe older than, say, 2006 or older.

     

    Also, check for app compatibilty  here.

    If you have any commercial antivirus installed and/or hard drive cleaning apps installed on your Mac, like MacKeeper, CleanMyMac, TuneUpMyMac, MacCleanse, etc. now would be a good time to completely uninstall this apps by doing a Google search to learn how to properly uninstall these types of apps.

    These types of apps will only cause your Mac issues later after the install of the new OS X version and you will have to completely uninstall these types of apps later.

    Once you have determined all of this, you should be able to find the latest version of Mavericks by clicking on the Mac App Store icon in the OS X Dock and then login to the Mac App Store using your Apple ID and password.

    You can then begin the download and installation process of installing OS X 10.9 Mavericks from the Mac App Store.
