Hi James and Justin, the 0.3.5 Mac version is now released. This has the same requirements as current Linux builds: Matlab2022a runtime (free), reg_aladin (niftyreg), ANTS. Tested on MacOS Sequoia 15.1.1 with an M2 "Silicon" chip. DICOM support was tested with dcm2niix (20241208 from Macports) and Python (3.10.16 from Macports) with modules pydicom 3.0.1 and nibabel 5.3.2. Please let me know if this works for you, and thank you for your patience as I worked on this.
