There was a previous thread on this general topic, but it seems that:

My MacBook (black, 2.2GHz) gets a dialog box that says "Mac OS X cannot be installed on this computer."

Why is this? I was gonna do a reinstall, but I'm running 10.5.2, is this the problem?

Thanks!

Are you using an install disc that came with another machine? If so, it will not work.

Nope, just a generic Leopard disk that I won in a drawing.

Are you just trying to reinstall or Archive and Install or Erase and Install? It makes a difference.

Well, once the dialog box comes up that says "you will be guided through the steps blah blah blah", I click OK, and it says it can't be installed.

Okay so what's happening is that the install disk has 10.5 on it and you already have 10.5.2 so it will refuse the install because you are trying to put a lower version of OS X on the computer. You have to go into "Options" which is on the install window and select either Archive and Install or Erase and Install so it can pull off the existing System Folder and allow for new installation.

Is the options button on the first box?

pastrychef
can you tell us why we are not able to use an install disc from another machine?
