External Email - Use Caution        

Are you using a second monitor, i.e., additional monitor besides the primary one?   There have been issues with images being displayed properly when using multiple monitors with MacOS.  I would first try everything on the primary monitor (disconnect any second monitor).

If you have not tried running freeview directly from the command line, e.g., to display a volume, then please try the following.  Open a new terminal window and run the bash shell,

$ bash
… prompt will change ...
$ export FREESURFER_HOME=/Applications/freesurfer/7.3.2
$ source $FREESURFER_HOME/SetUpFreeSurfer.sh

… output with variable settings …

… then see if freeview opens an empty window …

$ freeview

… then try to display one of the existing volumes in the distribution,

$ freeview $FREESURFER_HOME/subjects/bert/mri/brain.mgz

If you still see a blank screen, then try setting,

$ export QT_DEBUG_PLUGINS=1

… and run the command again.  The output may be useful.
