If you are using a Silicon Mac with an M1, M2, M3 chip, then please download and install the arm64 freesurfer development .pkg installer via the link, 

freesurfer-macOS-darwin_arm64-dev.pkg

Right click on the file freesurfer-macOS-darwin_arm64-dev.pkg and select “Open with —> installer.app (default)” which should bypass some of the security warnings.  Then follow the prompts to install (you will need to enter an admin password).

Then setup the freesurfer environment as usual, setting FREESURFER_HOME, sourcing the setup script.  Using this installer should avoid any error messages with “illegal instruction" from running the Intel binaries, e.g., from the 7.4.1 release.

Hello,

My name is Alisha Davis, and I have been using Freesurfer over the past few weeks for an MRI project but have encountered a few issues due to the version of my computer. Is there a plan to release a newer version of Freesurfer compatible with newer MacOS versions, or should I resort to reverting the update on my computer? I look forward to hearing back from you.

Thank you,
Alisha Davis
