The Internet Tablet Wiki (on this site) has information on updating using Mac OSX. It will point you to Flegg's gui updater. Unfortunately the instructions do not take into account the hardware differences between the N810 and the N800 (no card removal, no home button). And Flegg has sold his mac and not yet got a N810 (as of yesterday). So he can't be expected to add to the wiki. But if there is a N810 user who has updated on a mac, it would be very helpful if you could add to the ITT wiki. Thanks,
