It DOES work, Hans: there's a LOT of people there out using it. THE ONLY PROBLEM comes from an outdated ROM VERSION in our Mac Minis.
For me, it's "as soon as Amiga OS 4 runs on my mini, OSX can go hell".
And I repeat: IT'S usable, IT RUNS, and WE have to find a way to start using it in every Mac Mini with a PowerPC processor.
