    If you have a G4 PowerMac:


    Leopard System requirements


    You must have a Macintosh computer with:


    • an Intel processor or a PowerPC G4 (867 MHz or faster) or G5 processor
    • a DVD drive >built-in FireWire
    • at least 512 MB of RAM (additional RAM is recommended for development purposes)
    • a built-in display or a display connected to an Apple-supplied video card supported by your computer
    • at least 9 GB of disk space available, or 12 GB of disk space if you install the developer tools


    You can update to 10.5.8 but that is as far as you can go with a PPC Mac. You will need to search on Google, eBay, and/or Amazon.com for a retail copy of Leopard because it is no longer available through Apple. You can try AppleCare to see if they still have copies available for sale:

    He'll have a bit of a hard time upgrading to Snow Leopard on a PPC machine.

    Don't feel too badly. I do that all the time. I am forever guilty of such mistakes.

    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


    Upgrade beyond Snow Leopard

    Information about upgrading Snow Leopard to Lion or Mountain Lion: http://store.apple.com/us/product/MD256Z/A



    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.
