I'd like to upgrade my operating system from OS 10.05.08 to OS 10.06.04, mainly for using the new Magic Pad, which I bought.
Can anyone guide me how to make the upgrade?

    Purchase the retail Snow Leopard DVD. Do the following:

    1. Repairing the Hard Drive and Permissions

    Boot from your Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger and Leopard.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally.

    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.

    2. Clone using Restore Option of Disk Utility

    1. Open Disk Utility from the Utilities folder.
    2. Select the destination volume from the left side list.
    3. Click on the Erase tab in the DU main window. Set the format type to Mac OS Extended (journaled, if available) and click on the Erase button. This step can be skipped if the destination has already been freshly erased.
    4. Click on the Restore tab in the DU main window.
    5. Select the destination volume from the left side list and drag it to the Destination entry field.
    6. Select the source volume from the left side list and drag it to the Source entry field.
    7. Double-check you got it right, then click on the Restore button.

    Destination means the external backup drive.
    Source means the internal startup drive.

    3. Boot from the Snow Leopard DVD and install Snow Leopard. It will automatically upgrade your existing system. Because of the nature of upgrading the OS expect the process to take considerably more time than a new installation on a freshly erased drive.

    1. Be sure your system meets the minimum requirements for the upgrade.
    Info here: http://store.apple.com/us/product/MC573Z/A

    2. You need to purchase the 'Snow Leopard' OS X 10.6.x upgrade discs, available for $29 (US) direct from Apple, Apple Stores, and authorized Apple retailers, including some big-box electronics store locations.

    3. As with any upgrade, be certain you have (multiple) backups of your current files and programs, and sufficient free space on your hard drive for the installation. Time Machine backups on an external drive work. Snow Leopard is supposed to free up to 7 gigabytes of space that was once used by Leopard 10.5.x, once installed.

    Thanks for the detailed mail.

    My iMac has a 2.16 MHz Intel Core 2 Duo, and I couldn't find any numbers on its base, to check your list.

    Do you think the Snow Leopard will work on it properly?

    Only now I started to read comments on the upgrade to Snow and started to be a little afraid. I'm checking so deeply as I'v already bought the Magic pad and I wont to make it work.

    Tanks for the reply.

    How should I make the backup? just copy my files to a hard disk or is there an automatic way to make a backup.
    The Time machine is working all the time. How can I use its backup after installing the OS upgrade just by going back by one day?

    Backing up can be done at almost every stage, except a totally dead hard drive*:


    But simply dragging and dropping rarely backs up enough information unless everything that is not created by you is safely stored away on CDs at least twice.
