I thought I'd post this for anyone interested in free video editing software for Mac.
I downloaded this a few months back and have found it to be a very intuitive, easy to use piece of software (Very versatile too).
I originally used this to restore old Lp and cassette recordings - the Raygun plugin (which I purchased) is excellent for this, and then began experimenting with video.
For basic editing I highly recommend.
You can also find some windows audio software here.

Here's a brief introduction I grabbed from the site: (link is below).

Note this software was originally called Montage and sold for $149. (stability issues have snce been resolved and this is a nice app).
