1) Install the 7.3.2 release listed above. It will be installed as /Applications/freesurfer/7.3.2
2) Open a new terminal window and run the bash shell as,
$ arch -arm64 /bin/bash
3) Set FS_LICENSE to point to the license.txt file you downloaded after registering via the online form at https://surfer.nmr.mgh.harvard.edu/registration.html. For example, it could be in your home directory as $HOME/license.txt. It can be anywhere but you just have to set FS_LICENSE to its absolute path and test it can be read.
$ ls $HOME/license.txt
/Users/<your userid>/license.txt
$ export FS_LICENSE=$HOME/license.txt
$ head -1 $FS_LICENSE
4) Setup the environment,
$ export FREESURFER_HOME=/Applications/freesurfer/7.3.2
$ source $FREESURFER_HOME/SetUpFreeSurfer.sh

MNI_DIR /Applications/freesurfer/7.3.2/mni
5) Try running freeview from the command line w/o any arguments to see if it opens an empty window,
$ freeview
6) If that worked, quit freeview and then run freeview from the command line again to open one of the provided volumes in the 7.3.2 release,
$ freeview $SUBJECTS_DIR/bert/mri/brain.mgz
7) If that worked, then try running freeview from the command line on one of your own volume or surface files.
