Setup and Configuration
To begin using freesurfer, open a terminal window. The Terminal application is found under Applications -> Utilities -> Terminal:
Type the following lines in the terminal window to source the freesurfer environment:
export FREESURFER_HOME=/Applications/freesurfer source $FREESURFER_HOME/SetUpFreeSurfer.sh
After you source freesurfer you should see some output similar to the window below:
If you use freesurfer frequently and want to avoid typing the above lines of code every time you open a terminal window, you can create a file called .profile in your home directory which contains those two line. This will cause the terminal window to automatically source freesurfer every time it is opened.
At this point you are ready to begin using the freesurfer software. If you haven't done so already, obtain a license, and copy the license.txt file into your $FREESURFER_HOME (Applications/freesurfer) directory.
See the this page for some example commands to test that FreeSurfer is installed and running properly.
For Mac OS systems running freesurfer 6.0.0
If you receive the following error when running the test_commands.sh.15 script:

Then, you need to install a Freeview patch to have this work with your Mac OS version. Download the patch (~33 MB) from /autofs/cluster/pubftp/dist/freesurfer/6.0.0-patch/Freeview_6_0_0_MacOS_patch.zip follow the following instructions:
1)To download the patch, follow instructions on using the ftp file exchange from this wiki page.
2) Remove your existing Freeview.app application bundle by sending it to the trash (and then emptying the trash).You can also do this from the terminal by cd'ing to the top-level ./freesurfer subdirectory and then doing
rm -rf Freeview.app
3) Copy the new Freeview.app.zip to where your old Freeview.app was located and uncompress it (so it becomes the replacement Freeview.app in your current FreeSurfer installation).
4) Remove ./freesurfer/lib/gcc/lib/libgomp.1.dylib from your existing freesurfer installation.
5) Copy the ./freesurfer/lib/gcc/lib/libgomp.1.dylib from the patch archive to /freesurfer/lib/gcc/lib in your current freesurfer installtion.
6) Try running the Freeview.app and loading a volume with it.
