I've tried the GUI method on my Mac ibook G4 more than half a dozen times now. No luck so far. I successfully downloaded the 770 flasher and the latest Nokia image, opened the .bin file in the flasher, then disconnected and turned off my N800 as directed. I started the flasher but at this point got message and spinning wheel indicating that it could not find a suitable USB port (or words to that effect) and is "waiting". Assuming the program was just downloading a massive amount of data, I let it run for about thirty minutes, but the message remained and the little wheel kept spinning until I canceled.

Solutions tried: 1. Powered up and plugged the N800 into the USB port after the no-USB message appeared; 2. Started over, with the N800 plugged into the USB (but turned off) before starting); 3. Tried again with N800 plugged in and turned on; 4. Removed one, then both memory cards from the N800 and repeated all of the above; 5. Restarted the computer and repeated the above; 6. re-downloaded new copies of the flasher and image and repeated all the above again.

No luck. One other thing I noticed, which perhaps is related to my lack of success: when I plug the N800 into the computer, an icon appears indicating it is plugged in (two icons when both cards are inserted in the N800), but when I try to eject it, the icon keeps reappearing, so there's no apparent way to properly disconnect the N800 from the computer. Do all Apple owners have this problem?

Any ideas on what else I can try to update to OS2008?
