If the web browser you are using is not allowing the update to take place, do you have the Old Desktop Software?
The Old Desktop Software avoids the web browser and runs directly on your desktop..
If you do not have the software, please click on the one of the following links below for your computer:
After installing this software on your computer, run the setup through the "Setup Assistant" option.
Let me know if this works for you please.

My Macbook Pro (the same one iv'e always had including during original SB install several years ago) continues to gove me a discouraging error message while trying to update the firmware for my old SB "Solo'" 260-100. It tells me to trash it and not use it although its the older Mac version you suggest.
