I have an older G4 that I just got a DVR-107D for and I noticed that it was shipped with FW 1.10, instead of 1.13. Any chance I can update this FW on the Mac (OS X 10.3.3) instead of having to tear it out again and pop it in my PC?
Bad News: NO
There is no tool for A07 on Mac, neither for OSX or OS9.
So the only option is to put on a PC, but if you don't own a PC ask a friend ho has it.
