If you're smart enough to use a Mac or *nix box, you don't need no stinking wizards ...

I've updated my N800 using the good old "flasher-2.0.macosx" provided by Nokia.

The only thing you have to do special is run it as root. So assuming you are a administrator on your mac, just open a terminal where you downloaded the flasher and image files and type "sudo ./flasher-2.0.macosx" and add all the command line switches the same as linux.

Basically it is exactly the same as linux except the name of the flasher binary is different. But I did the "leaked" OS2008 image on my mac and used the linux instructions and it worked just fine.
