how to upgrade from mac os x 10.4.11 to 10.5


MacBook Pro, Mac OS X (10.4.11)

    Purchase Mac OS X 10.6 on DVD from the online Apple Store. Since you're using an Intel Mac, it's generally not worth finding and purchasing Mac OS X 10.5.

    As Niel relaters...

     

    Leopard requirements/10.5.x...

     

        *  Mac computer with an Intel, PowerPC G5, or PowerPC G4 (867MHz or faster) processor

     

    minimum system requirements

     

        * 512MB of memory (I say 1.5GB for PPC at least, 2-3GB minimum for IntelMacs)

        * DVD drive for installation

        * 9GB of available disk space (I say 30GB at least)

    Trouble is Apple no longer sells it, check eBay & such for the Retail version, not the Gray Discs...

    Snow Leopard/10.6.x Requirements...

     

    General requirements

       * Mac computer with an Intel processor

        * 1GB of memory (I say 4GB at least)

        * 5GB of available disk space (I say 30GB at least)

        * DVD drive for installation

        * Some features require a compatible Internet service provider; fees may apply.

        * Some features require Apple’s MobileMe service; fees and terms apply.

     

    Which apps work with Mac OS X 10.6?...

    It looks like they might still have it...

    It's reported that if you have a MobileMe account that Apple will send you SL/10.6 for free.

     

    If it's a core Duo & not a Core2Duo, then it'll only run in 32 bit mode.

    Backup first

    It is always best to have a full bootable backup before you upgrade. If you fail to do this you will be unable to return to this OS if you decide you don't like the new OS. Also there is a slight chance that an install could lose everything on the Mac. The backup must be to an external hard disk. Preferably use Carbon Copy Cloner to make a bootable backup of the whole disk.

     

    Erase before the install

    Once you have a bootable backup on an external disk it is best to erase the internal disk with the new installer DVD before you install.

     

    During the install

    Preferably do not import any data or preferences from earlier OSs during the install process as this can reintroduce bugs.

     

    OS numbers and names

    OS X 10.4.x - Tiger

    OS X 10.5.x - Leopard

    OS X 10.6.x - Snow Leopard

    OS X 10.7.x - Lion

    OS X 10.8.x - Mountain Lion

    Upgrade to Leopard

    Those wishing to upgrade to Leopard should be aware that install disks can be expensive unless you contact Apple. Details: http://lowendmac.com/deals/best-os-x-leopard-prices.html Standard Leopard installers impose several hardware limitations including speed and RAM size but all these restrictions can be overcome. Google for details. Leopard works well at 500 MHz with 1 GB of RAM and many happy users have less than this.

     

    Upgrade beyond Leopard

    OSs beyond OS X 10.5.8 require an Intel processor. If in doubt check this: Click the apple at the top left of your screen and select 'About this Mac'. This will give you your OS number. Then click 'More Info' to see which processor you have. If it says PowerPC you cannot upgrade to Snow Leopard and above. If you have an Intel Mac it is well worth upgrading to Snow Leopard now and then considering other options after that. You can buy Snow Leopard here: http://store.apple.com/us/product/MC573Z/A

    Important

    Check that your Mac complies with any requirements. If you are not in the US you should use the Change Country link at the bottom of Apple pages.
