The Cuda will not work on the Mac1,1 or 2,1 because those computers boot into 32bit kernel mode only. There is a hack to get them to boot into 64bit kernel mode, but it’s a little complex. That is why it will not recognize it. Here is a link to the 64bit hack if you are brave:

I tried it, but it was too unstable for me. When it did work, it was awesome. I ended up taking out the GTX570 and putting the AMD5770 back in and booting normally. If I upgrade to a newer macpro I’ll put the GTX570 back in.
