I used the 10.4.11 intel combo updater...

…for the smart install. It’s alias shows up in cyberduck when I am transferring new media to my external usb HD. Do I need to keep this on the aTV? Or can I trash it now that aTV has it’s data?

I am no expert, but I have read in other places where once you use the 10.4.11 for your intended use, you can remove it. But… why? You may find you need it later for something else. It doesn’t take up that much room.

I would keep the Combo Updater on the AppleTV, it really does not take up that much space. That way if you need to run the Smart Updater again after an aTV Flash update then it is already there for you.
