I have been trying for weeks to install Mac OS X Snow Leopard on my iMac Late 2006. I have been having trouble lately due to the installation saying that Mac OS X cannot be installed, although I have installed this version of Mac OS before. I have been following this guide listed below and was able to install OS X Snow Leopard before. I have gone into Terminal via the install disc and attempted to enable root privileges, but it says "-bash: su: command not found". Any help would be appreciated, and thanks in advance.


  • you say you've installed this version of Mac OS before, but was it with this disk? – dwightk Mar 20 at 16:38

    The Terminal available during an install is a root terminal and the use of su isn't required. As the late 2006 iMac didn't ship with Snow Leopard, the disc needs to be a retail disc, not one that shipped with another Mac. Is the disc you have a retail disc or one shipped with a different Mac? – user3439894 Mar 20 at 16:48
  • How do you find out if the disc is from retail or not? – Ian Pootis Mar 20 at 17:05
  • Yes, the mac OS disc used before was used. I think I did something inside the installer menu using a terminal to force the installer to cooperate. – Ian Pootis Mar 20 at 17:06
  • Does the DVD look like this? – David Anderson Mar 20 at 17:07
