One way of installing GDAL on your Mac is via Homebrew (http://brew.sh). First install Homebrew, then `brew install gdal` in a Terminal to install GDAL.

I second the use of `homebrew` but there's also a pretty [comprehensive explanation](http://tlocoh.r-forge.r-project.org/mac_rgeos_rgdal.html) of how to do this on OS X (not requiring `homebrew` and offering 3 alternative ways).
