Selling the iMac and wanted to reinstall factory settings. When I checked how to do this it's asking to insert a disk but I don't have a disk. How can I reset without the disk?

    You will need the original DVD, If your iMac shipped with Mac OS X 10.7 (Lion) then your can use the Lion recovery (command + R) when restarting your iMac then do a clean install of Lion.

    If you posted some information about your system, OS version. Hardware Version etc.

    i'm sure someone will be able to help you.

    As advised you need the orignal Install Disk because you don't have yours call AppleCare and for a nominal charge they will replace it. You will need the serial number and a credit card.

    It is best to have the original DVD set or at the least, a Retail Upgrade Disc when selling an iMac.


    Because I'm not sure exactlly which model iMac you have, it's hard to say exactly what OS X Upgrade Disc version you can use.


    For example:


    If the iMac is an Intel Core 2 Duo between 2007 and 2010 then Lion from the App Store will work


    If the iMac is an Intel Core Duo or Core 2 Duo between Early 2006 and 2009 then a retail Snow Leopard Upgrade Disc will work.


    If the iMac has a PowerPC processor, then you will need to either call Apple or hunt around for a retail Tiger or Leopard Upgrade Disc.



    Better yet, contact Apple and request a replacement Disc set for that iMac.
