Bad news from comments: while the white MacBook has the same mini-DVI output as its predecessor, it doesn’t work with adapters that support TV out. That means, basically, forget what I said earlier.
This adapter is not compatible with the 2.0GHz Intel Core 2 Duo white MacBook introduced in January 2009.
Oddly, as far as I know the card itself should support TV out. So anyone who thinks this is all some DRM conspiracy, more fodder – though the same machines still do support VGA analog out, which is not a protected path and could itself allow piracy. I’m stumped. I think maybe computer makers think we don’t want TV out any more. Open to theories.
Thanks, janeoblivion. And no thanks to you, Apple / NVIDIA / shadowy forces who have aligned against our TV out, darnit.
