There is an imcompatibility with the original bootloader firmware and some Mac devices. You really only have two options: update from a PC, or send it to Brewers Hardware to have the latest bootloader firmware installed (which would then allow you to update from a Mac in the future).

JonW,

Thanks I was able to update the firmware on our backup unit but this one seems to hang. I will see if I can track down a PC.
