    I have a huge dmg file of an application, that
    is 7 GB large.
    My disk burner is not letting my burn dual layer DVD's,
    so is it possible to split the file onto 2 DVD's ?

    If so, how would you recompile them to load onto another Mac ??

    thanks!

    Yes you can. You just need to use the 'hdiutil segment' command to do so. See the hdiutil man page for instructions. As long as you have the two image parts next to each other when you click on the first one it will open as if it was a single file.

    im pretty sure "Split and Concat" will work for you. It is just that you have to join them when you want to mount them.

    You can split any large file to fit across DVDs using either the unix split command (example) or hdiutil segment (macrumors thread) command.

    I would just use split, mainly because I'm used to it in Linux. And it's easy to "cat" the split file back together.

    You could up your OS X install disk this way, but I don't see that it would be useful. The split files are useful only when joined back together, and to use your OS X install disk, you'd need it on a single DVD anyway.
