A probable issue for my macbook with arm-cores, is this a common issue?

Hi, mrtrix experts,

A problem lets me cannot observe tracts in the mrview window, the loading time is too long to observe them. My platform is the MacBook pro-2021, and the mrtrix3 was installed following the approach below.

sudo bash -c "$(curl -fsSL https://raw.githubusercontent.com/MRtrix3/macos-installer/master/install)"

BTW, I also tried to install mrtrix3 by miniconda, errors were reported, although I changed several different conda sources in the .condarc.

PackagesNotFoundError: The following packages are not available from current channels:
  - mrtrix3
Current channels:
  - https://conda.anaconda.org/mrtrix3/osx-arm64
  - https://conda.anaconda.org/mrtrix3/noarch

Is there any approach to bypass or resolve the above two problems?

Thanks,
Feihong Liu

A workaround can be found here: Issues with pseudotube rendering on Apple M1 macs

I added ‘MRViewDefaultTractGeomType: Lines’ to the ~/.mrtrix.conf, it works well.

We suspect that these issues arise from the way Apple translates our GLSL geometry shaders to the Metal API.

Thanks!
