You can try using the Silicon Mac development build on the M2 machine. The download links is,

MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer/dev/freesurfer-macOS-darwin_arm64-dev-20240327.pkg

Right click on the pkg installer and then select the “open with installer.app …” option.

Hi Koen and Doug,

I am trying to do similar analysis but when I run run_samseg command, it gives me error "Illegal Instruction: 4"

I am using the FreeSurfer 7.4.1 version on Apple M2 Max MacBook Pro 14.4.1.

Is it because run_samseg is incompatible with Apple M2? If so, could you please suggest any solution (if available) how I can run run_samseg on my Apple M2 computer?

Thanks.
