It's the GMA 950 video... last supported version is Lion (10.7), though there are hacks to install ML. For the latter, though, you would need to purchase/dl 10.8 from a compatible computer.

SPOILER tags do not work here and are unnecessary for your post.

Anyway, as the installer says, your MacBook is not supported to run OS X 10.8 Mountain Lion officially.

Anyway, on the front page of this very sub-forum this thread is listed:

[Guide] Success! Install 10.8 on old unsupported Mac​

Thanks for your help guys, I will use MLPost app to make it work... Do you recommend me doing it?
