I came in late on this thread, so I don't know if this was mentioned, please excuse if it was. I was able to run the firmware updates by using VirtualPC, which I had purchased with my iMac, so that the wife could run her medical software. Of course, it's not worth going out and buying it just for the ease of upgrading a router, but if you already have it, it's an option. My 2¢ fwiw. Cheers, John
