External Email - Use Caution        

 
The current 7.4.1 (Intel binary) release from June 2023 should run on Silicon Macs and I believe was tested with MacOS (13.X) Ventura.  We did not have MacOS (14.X) Sonoma available at that time for testing.  The Freeview image viewing application requires graphics/X-Windows and for that you need X-Quartz installed on your Mac.  We have a native Silicon Mac development build available but it is currently unstable.

The graphics card spec assumed the graphics card has its own dedicated memory.  That spec is somewhat obsolete now w.r.t Silicon Macs since their unified memory design means the CPU’s and GPU’s share the same memory..  The spec to look for on Silicon Macs is how large is “unified memory”.

Commands that are python scripts (and not Intel or arm64 binaries) using modules like tensorflow may not work on Silicon Macs when trying to utilize the GPU’s.

If you have not already done so, download and install Xquartz,

https://www.xquartz.org

The 7.4.1 installer package can be downloaded from,

https://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer/7.4.1/freesurfer-macOS-darwin_x86_64-7.4.1.pkg

RIGHT CLICK on the installer package and under “install with” select the default installer.app.  This should bypass having to open system preferences to make a security exemption.

There seems to be some contention if FreeSurfer will support Mac OS
silicon (M2, M3) computers. In the technical requirements section, it
is clearly specified that a " 3D graphics card with its own graphics
memory & accelerated OpenGL drivers" is required. But in the email
archive (caution suggested) it is noted that "binaries should run on
current Macs with M1, M2, M3 arm64".

Currently. Apple has not indicated plans to support eGPUs, which, on
paper, makes all newer non-intel Mac computers not compatible with
FreeSurfer.

Any suggestions would be greatly appreciated.
