    I'm still new to mac os x. I need help opening up an application after downloading it. I'm trying to open up what I downloaded but it's saying the application is unknown and there is no default program to open it with. I don't know what to use. It's so annoying. Help anyone?

    Undoubtedly it's compressed and has a .sit suffix.

    You need to download Stuffit Expander.
