The Freesdurfer release page,https://secure-web.cisco.com/1aFSeUS1wPG9NyqX8ojDowAxZz8EG0dwH-X32J5_0FOZesC... - shows the Freesurfer 7.4.1 release from June 2023 was never tested on MacOS Tahoe, i.e., the latest release at the time was MacOS 13 (Ventura).7.4.1 releaseLinux OS: CentOS7, CentOS8, Ubuntu18, Ubuntu20, Ubuntu22 release notes Mac OS: 10.15; 11.X, 12.X, 13.X (Intel binaries only running under Rosetta).The 7.4.1 binaries were built for Intel processors. Even if you are running 7.4.1 on MacOS Tahoe with older Mac hardware using an Intel processor it might be something is working differently on MacOS Tahoe. If you are running Freesurfer 7.4.1 Intel binaries on newer Mac hardware with an M1, M2, M3, M3 processor, then you are running those binaries thru the rosetta emulation environment. That might also cause something not to work as expected. Unless you absolutely have to continue to use 7.4.1, e.g., continuity for processing some subject data, then I suggest you try running the same commands with the most recent Freesurfer release which is 8.2.0 from March of 2026.8.2.0 release Linux OS: CentOS7, Rocky8, Rocky9, Ubuntu22, Ubuntu24 release notes Mac OS: 13.X (Ventura), 14.X (Sonoma), 15.X (Sequoia) 25.1 (Tahoe) with separate Intel and arm64 installers. Mac M1, M2, M3, M4 ... processor equipped arm64 machines should have 32G+ RAM to use the new/faster recon-all setup and its associated commands. Otherwise you may revert the recon-all process to the pre-8.X version.For older Mac hardware using an Intel processor you would install,https://secure-web.cisco.com/1s39BkWvbDcqfN0R06Xfq48pjE1wm1GEgpPfyTR4SLCiQZ6...
