I have a Sanyo scp-2700 cell and a Mac G3 running OS X 10.4.1. I want to upload my photos from my cell to my Mac, but when I use the USB cord nothing happens. What am I missing? A software? Neither device recognizes each other I’m confident.
First you should look into System Profiler under Hardware - USB whether the phone was recognized or not. If it wasn't try a different USB Port (I suggest to use one directly on your computer, not the keyboard).
Unless it was a typo I also suggest to update to Mac OS X 10.4.11 to prevent any compatibility issues.
