I made a previous thread saying that I would like to restore my iMac, I got nothing but a link to a website talking about basic stuff about Time Machine.


So I researched stuff and thought I might as well go ahead.


I watched a video beforehand and they said you should insert the install disc, select install/restart and it'll boot from the disc, then erase the hard drive and start installing Snow Leopard.


Done that, then it said the install failed, so I restarted and tried installing again, failed.


Removed the third party RAM.




Now what? It says "The Installer could not copy the necessary support files."


I'm thinking of:

  • Putting Snow Leopard on an external USB drive, but the threads I've found talking about that are from people who are booting from the hard disk
  • Inserting a different Snow Leopard disc (One that didn't come with the computer) but I can't remove the current disc because that's where it's booting from
  • Going to the Apple Store
  • ...restoring with a Time Machine backup...but I don't want everything which is the point of reinstalling Snow Leopard
