Dear Apple bits and bytes,

my "stone-aged" iMAC, PPC - not Intel - 1st generation, needs an upgrade from 10.4.11 to 10.5.8.

Do you - in any case reccomend a full backup of all contents in the HD? The old OSX 10.4.11 included.

Or can I leave it on the harddisk and just overwrite the old 10.4.11 to the next and least possible OSX 10.5 an its updates up to 10.5.8. -

still some kind of late "iron-age" OS?

Thank you all

iMac, Mac OS X (10.4.11), G5 Processor

    We're not Apple - just other users here.


    Always have a backup before attempting updates, upgrades or security updates.


    In fact, always have an up-to-date backup, full stop.


    All G5s can run up to Leopard 10.5.8. Getting it however…


    You'll need a Leopard retail install disk.

    Mac OS X 10.5 Leopard installation system requirements



    Leopard is no longer available at the Apple Store but may be available by calling Apple Phone Sales @ 1-800-MY-APPLE (1-800-692-7753). {Note - this is now very unlikely, but no harm in asking}.


    If you can't obtain a retail install DVD from Apple, look on Amazon MP, eBay or Google the installer part numbers to possibly find at an on-line store. Here's what to look for:


    MB427Z/A  Leopard 10.5.1 install DVD

    MB576Z/A  Leopard 10.5.4 install DVD

    MB021Z/A , MC094Z/A  Leopard 10.5.6 install DVD (single user)

    MB022Z/A , MC095Z/A Leopard 10.5.6 install DVD (5-user family pack)

    {the bold order numbers are the later ones}

    After you install the base 10.5, download & install the 10.5.8 combo update at http://support.apple.com/downloads/Mac_OS_X_10_5_8_Combo_Update

    {This is still available on Support Downloads}
