How do I restore to factory settings? I don't have any of the disks. This was a hand me down computer.

iMac, Mac OS X (10.4.11)

    Is that an early intel-based iMac? coreduo/core2duo?

    Or a similar looking iMac G5? powerPC


    Or maybe is it an iMac G4?

    (one with LED on chrome arm)


    Or some older iMac G3 w/CRT?

    Colors/all-in-one. limited upgrades.


    see pictures - http://support.apple.com/kb/HT2452 -find serial number.


    If you can identify the exact model of the iMac, that may be helpful.


    Various build year models have different hardware, & upgrade limits.

    So that could be an older powerPC iMac G4 with 15/17/20" LED, or

    maybe a powerPC iMac G5 with 17/20" display, looks like early intel.

    Or it could be an early intel-based iMac, some first ones had Tiger.


    If you have found the serial number, that can help lookup info:



    Consider Mactracker http://mactracker.ca for download info database.


    You may be able to get a restore Tiger 10.4.x or Leopard 10.5 disc (or

    both) for iMac once you get the serial number & other info, from a source

    at Apple support, cited on the following link, & are hard to get. (for a fee.)


    {this found in ASC thread about resolving internet issue}



    Hopefully this helps somewhat.

    Good luck & happy computing!

    If you are in the US call Apple Customer Support 1-800-767-2775, provide the Serial Number and specifications of the Mac, and for a reasonable fee, they will supply a replacement set of system discs (if available).


    The discs will be for the original version of the OS that was pre-installed when the Mac was manufactured.
