I Just Purchased A Used Apple Imac G4 (2002), What Software/Hardware Do I Need To Purchase To Bring My Computer Up To Date? My Computer Currently Runs Slow And I Cannot Use Itunes On Outdated Software. When I try To Download Newer Software I Am Unable To?

    OK, a 2002 G4 is quite old for a main computer but is still usable if you don't do too many intensive tasks.

    Please go to >About this Mac for information on your computer. Screenshot the About this Mac window and post it here, or post the info you see in the box.

    OK, you are currently running the latest OS X version your iMac can run (unless you use a hack). You could consider upgrading the RAM, this will speed up your computer. Search "iMac G4 RAM upgrade" on YouTube or iFixit for some help with this.

    I Found Thermal Paste Online And The Following Ram:

    1 Certified Apple Compatible 512mb PC2100 DDR Memory stick.

    Would This Be The Right Memory Stick?

    Thank You For Pointing Me In The Right Direction.

    I Found Instructions On Ifixit......

    There is quite a bit of nostalsia for the "Luxo iMac:"

    My daughter purchased one and we used it to run Mac OS X Tiger Server for quite a few years.  I will never dump it!


    The highest level of Mac OS X that will run on this computer is Mac OS X Leopard 10.5.8.  Apple no longer sells Leopard.  You can find it on eBay, but it is pricey.  Additional RAM is ALWAYS helpful: check out OWC and other Mac memory websites for the best information and prices. Usually you must replace old RAM modules with new ones to add RAM; infrequently, you can add to the existing RAM chips.


    iFixit is a good source of information.

    I think that is the correct RAM module.

    To MichaelLAX - This G4 won't run Leopard as Leopard requires a 867MHz processor.

    Thanks for the correction: While I never personally upgraded my iMac G4 to Leopard from Tiger Server, there are threads that discuss its ability to run it; for example:




    So the OP can choose to find Tiger on eBay and install that instead.  Will Apple still update OS X Tiger 10.4 in Software Updates?

  • edex67 Level 4 (3,250 points)

    Actually, it could run Leopard, but only with a hack (LeopardAssist) which in my experience hasn't worked well.

    10.4 is no longer supported so there is no more software updates.
