If you have a recent version of XCode installed then you can build from source.

1. Get the sage-3.4.tar file here: http://sagemath.org/src/

2. Extract it (possibly by double clicking on it).

3. Using terminal, change into the sage-3.4 directory, and type

    $  make

This will take a couple of hours, and will likely work fine so long as
you have an xcode that is from at least about 2007 or newer.
