After my previous post about the older versions of Safari no longer working I tried Safari 3 again. When I got to the upload page it said that a new version of Garmin Communicator had been released. Make sure you look carefully at that page. The GIANT button that says Download on it is a link to the Windows version. About half way down the page is a link for the Mac version.
The Communicator Plugin is much cooler as it lets you upload from Firefox. After I installed that, and restarted Firefox I was ready to go.
As of right now I have no use for Safari.
Thanks for the tip, I just downloaded the new plugin. I was putting off applying the latest OSX update because I didn’t want mess with Safari versions, but I should be set now.
