I was very disappointed to find that the firmware upload software for the MIiFI4510L was not compatible for the PPC Macs. I have 3. If there a workaround available? There was nothing to indicate that the software was for Mac OS X Intel only when I downloaded the software package. The drivers installed on my PPC Macs with no problem. However, when I tried to install the the firmware upload software, I get the message that this software is not supported by the PPC architecture.
