My iMac hard drive died and I got a new one installed from Apple and my dad's friend installed Leopard for me and he started to download and install the updates from Apple and I don't know if he stopped the install midway but when I tried to download and install them NONE of them install. I called Apple and they told me to try something in Disk Utility with "verify disk" and it didn't work still and then they sent me something about trying to Archive and Installing but it seems really complicated. Is there anything else I can try?
