I have a 2006 iMac and a backup and would like to restore the to the original install. However, it can't be upgraded, its too old, so finding software is impossible.

Tried the Mac OS X Tiger system disk, which is the oldest I have, but its too new!

Tried setting NVRAM, no response. Command+R, no response.

Does anyone know how to do it?

  • You say the Tiger disc is "too new". What happens when you try to use the disc? Do you get nothing on screen? Do you get an error? – NetherLinks Oct 16 '16 at 18:24
  • Please note that Tiger is NOT too new for that computer. The newest OS that that computer can handle is Snow Leopard (10.6.8). Tiger is 10.4. – NoahL Oct 17 '16 at 3:22
  • Try inserting the Tiger disc. When you start the computer, hold down the "C" key until you see an image on the screen – NoahL Oct 17 '16 at 3:24
