I have always wondered this, but can anybody explain the difference between the Flash Updates section vs. the Mac OS X section?

For the case of the ADI-2 Pro FS, the two sections/files seem the same.

For the HDSP AES card, the two sections are different.

I find it confusing as to what is going on and always just install the newest version but what is really going on here?

This is what I'm looking at:

I'm guessing Flash is the firmware update and the Mac section is Total Mix and the HDSPe controller app but it seems like sometimes those come in both packages...or maybe it's because the ADI-2 Pro FS doesn't have a MacOS app.

Overall, I'd say the way the updates are presented is slightly confusing.
