External Email - Use Caution        

That didn’t work either, I’m afraid :( 

One other detail that may help: whenever I try to launch Freeview, a window pops up that says “Do you want the application “Freeview.app” to accept incoming rework connections?” “Deny” or “Allow.” (See screenshot below). 

However, that also occurred when Freeview used to work fine on this machine. The same window appears whenever I launch Matlab, but doesn’t cause any problems. I have tried editing the Firewall settings for both applications, to no effect. 

Thanks
Alex

Hi Ruopeng 

I tried deleting that .plist file, but it did not work, even after restarting the machine. The same PETSC crash occurred when I try to start Freeview either through the terminal or clicking on the icon. 

Thanks for your continued help, 
Alex

/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: 

[0]PETSC 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.
