iMac a1174 2006 How to restore factory OS? I don't have the password and it doesn't boot into recovery mode (cmd-r) or Startup Manager (control)
I am trying to reinstall a fresh OS on an old iMac (a1174) that doesn't appear to be able to boot into recovery mode. I don't have the password, so I can't login.
I tried downloading a .dmg file and tried to boot from a .dmg on a USB, but I can't get it to go to Startup Mode.
Do I need to get the original CDs to install the OS? If so, where do I get them?
