fileReference(List) uload doesn't work on Mac?!

We have found the same problem. I've read several blog entries that indicate this is a known problem and that Adobe is actually calling it a bug. Supposedly it will be fixed in Flash Player version 9. In the meantime, the bloggers/developers are suggesting you echo a blank string out to the browser in your upload script. In PHP, for example, you would add a line like the following:

echo "";

I implemented the "nothing" echo and all of our Mac people are still not getting that onComplete event to fire. I get some to work OK by adding a timeout in the onProgress event. In the onProgress event, when the bytes loaded equals the bytes total, I fire up a timer that "hand fires" the custom onComplete function. I set the onComplete event to fire that same function, as well. The code looks something like this:

That makes it work SOMETIMES. We're still getting hit and miss uploads on Macs. It is very definitely a Mac Flash player bug, IMHO. I've been able to get uploads to work more often in Firefox on a Mac, than on Safari.
