    I am surprised to find that right clicking on any icon and going to "open with..." shows 2 of each application that can be opened. Why does this happen? Is it a result of some corruption of some sort?

    Having encountered this problem using 10.9 out of the box, I just want to make sure that my new hardware isn't causing any software glitches like this.

    It's not hardware related.

    It's just that Launch Services has a tendency to mess up sometimes, especially if you are working with cloned images. Again, I'm not really sure what causes it to do that.

    The above post has a terminal command to rebuild the LaunchServices database. It doesn't prevent the problem from happening again, it's just a temporary solution.

    But repairing permissions after following the above instructions might be the end of it? Has worked in the past, but I haven't yet encountered this problem with Mavericks.

    Let us know if it works.

    Just reset Launch Services database and restart Finder.
