    Hi,
    I am in the process of upgrading my Macs to Mac OS X Lion..
    As you know, once I buy it from the App Store for 29.99$, I can use it for all of my Macs..

    But the question is:
    Do I need to download it on every Mac again?
    Can't I just download it once, and then use the same downloaded App for my other Mac?

    Note: I have MacBook Pro, Mac Pro, iMac..

    If you open the package contents of the installer and find the dmg file, you can burn it to a DVD and install Lion on other Macs that way. It's worth keeping a DVD backup of the OS anyway incase things don't go to plan later on.

    Or you can just copy the installer from your applications folder to a flash drive and copy it to another computer. :)

    You don't even have to do that, just drag the installer onto a flash drive and copy it onto the mac you want to install.

    Note that if you download it and install before making a backup, Lion will delete the installer automatically at the end of installation.

    Nope you don't. Just the same Apple ID is needed.

    Actually, it's not. You just need your Apple ID to download it the first time.
