I have found another possible workaround for this, which I will post here so I have somewhere to send people. (The Meshlab workaround still works, but this one doesn't require meshlab)
MM will (currently, as of v2.1) not work with the coverflow or large-icon modes of the Finder file windows. If you switch to one of those icons, and then open/import a file, it will either crash or be non-responsive, and then crash on exit. The latter is what happens on my MBAir and MBPro, with 10.9.1.
To work around this, first go to the Import finder dialog and select one of the middle two list-view icon modes. Then Cancel the dialog, and exit meshmixer (if it does not crash). If it crashes on closing the dialog for you, you might try exiting while the dialog is still visible. In this case (for me) the UI is still frozen, and when I exit MM it will still crash.
But, if I now re-open MM, and go to Import, and pick a file, it will render correctly, and I can use MM. However, it will still crash on exit, once. But on a second attempt, it does not crash anymore.
