I just bought a used macbook pro and once I powered it up I just followed the steps to set it up, once done, the OS is 10.5.8. I want to upgrade it to Snow Leopard but what's the best way to do it? I already spent half a day setting many things up, and I don't want to start everything all over again, what's the best way to upgrade? I don't want to have SL on a different partition. Thanks in advance!


MacBook Pro, Mac OS X (10.5.8)

    Back your existing system up and then start the Mac OS X 10.6 installer.

    How to Install OS X Updates Successfully

     

    A. Repair the Hard Drive and Permissions:

     

    Boot from your current OS X Installer disc. After the installer loads select your language and click on the Continue button. Then select Disk Utility from the Utilities menu. 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 (4.0 for Tiger) and/or TechTool Pro (4.5.2 for Tiger) 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.

     

    B. Make a Bootable Backup 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 Restore tab in the DU main window.
    4. Check the box labeled Erase destination.
    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.

     

    C. Important: Please read before installing:

     

    1. If you have a FireWire hard drive connected, disconnect it before installing the update unless you will boot from this drive and install the update on it. Reconnect it and turn it back on after installation is complete and you've restarted.
    2. You may experience unexpected results if you have installed third-party system software modifications, or if you have modified the operating system through other means. (This does not apply to normal application software installation.)
    3. The installation process should not be interrupted. If a power outage or other interruption occurs during installation, use the standalone installer (see below) from Apple Downloads to update.  While the installation is in progress do not use the computer.

      

    D. To upgrade:

     

    Purchase the Snow Leopard Retail DVD.

    Boot From The OS X Installer Disc:

     

      1. Insert OS X Installer Disc into the optical drive.
      2. Restart the computer.
      3. Immediately after the chime press and hold down the "C" key.
      4. Release the key when the spinning gear below the dark gray Apple logo appears.
      5. Wait for installer to finish loading.

     

    E. If updating:

     

    1. Download and install update(s)
    2. Use Software Update, or
    3. Download standalone updater(s).

    Easy, buy the 10.6 disk here

     

    http://store.apple.com/us/product/MC573Z/A

     

     

    Make a backup of your personal data off the machine and disconnect the drive just in case

     

     

    Stick the disk in and doubleclick on the installer, or hold the c or option key down and boot from the disk and click the installer. Reboot, hit Software update under the Apple menu.

     

    Piece of cake.

     

    Nothing will be changed with your files, settings or programs. Some programs may need to be updated or reinstalled from fresh sources for 10.6, but most programs of 10.5 will work in 10.6 because of Rosetta. (no Rosetta in 10.7)

     

    It's when you go to 10.7 that a lot of your 10.5 programs and third party hardware drivers will not work, so be careful and check first with all your hardware makers BEFORE upgrading to 10.7!
