External Email - Use Caution

The graphics packages used in Freeview have changed since the Freesurfer 6 release, and also how they and the other Intel binaries are compiled for current versions of MacOS.   So a run time error, e.g., segfault, could occur when running under Rosetta on a silicon Mac.

Please try one of the current MacOS Freesurfer 7 releases from the download page, surfer.nmr.mgh.harvard.edu/fswiki/rel7downloads

Hello,

I recently installed Free Surfer 6, and was following this guide: MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://secure-web.cisco.com/1NRP4tsM45lW3UFB3Jf_X6qXB5GUcDVNjcJDXPLcS2Shw2L...

I got till Example 3, and Example 3 works perfectly. As attached as an image in this email. 

For some reason, in Example 4, to open the GUI (freeview) based on the fully recon-ed subject bert in Example 3, I get an error and I'm not sure why. Why does that happen? Is it due to compatibility issues with the apple silicon chip? The error message is attached as an image in this email as well.

Any help is appreciated. Thank you.
