Can you delete this file and wait for a minute and then try starting freeview 
again?
/Users/USERNAME/Library/Preferences/edu.harvard.mgh.nmr.FreeView.plist

Replace USERNAME with your actual username.

Hello Ruopeng,

Thanks for the quick reply!

I tried launching Freeview by double-clicking on the app icon, and I tried 
installing the latest build. The same crash occurs (full output copied again 
below.

Also, I do have XQuartz 2.7.11 and it can run xeyes. And yes, FREESURFER_HOME 
and SetUpFreesurfer.sh both reference the current version 7.1.0. I didn’t see 
any LD_LIBRARY_PATH in my shell init file. Here’s what’s in my .bashrc file:

% cat .bashrc

#set freesurfer directories and set up script
export FREESURFER_HOME=/Applications/freesurfer/7.1.0
export SUBJECTS_DIR=$FREESURFER_HOME/subjects
source $FREESURFER_HOME/SetUpFreeSurfer.sh

Any other ideas?

Thanks,
Alex

HI Alex,

Have you tried launching freeview by double-clicking freeview.app bundle?

Can you also try the latest build from here?

Hello freesurfer team!

I can’t get Freeview to start up on my Mac (Catalina v 10.15.15).

It worked intermittently earlier this year, then stopped working. I updated 
Freeview, and then all of freesurfer, and still have the same problem. So now I 
have this version of freesurfer:  freesurfer-darwin-macOS-7.1.0-20200511-813297b

Typing “freeview” into the terminal generates the following error:

I searched through the log of previous emails and found several others with 
“PETSC errors” but could not discern a common solution.

Help?

Thank you,
Alex White

PS: I also can’t get Freeview to launch on a linux machine, and will send a 
report on that in a separate email.
