Hi,

I’m trying to install and use the **SlicerRadiomics** extension on my Mac, but I haven’t been able to get it to show up, despite following all the instructions.

System Info:

- **macOS version** : 15.5 (Sequoia)
- **Slicer version** : 5.9.0-2025-05-25 r33658 (Preview build)
- **Slicer install location** : Application moved to `/Applications` as required

What I Tried:

1. Opened the Extension Manager and searched for **“Radiomics”** — nothing appeared.
2. Verified I’m using the **Preview** , not Stable.
3. Downloaded the zipped folders from GitHub: `SlicerRadiomics` and `SlicerRadiomicsCLI`
4. Tried manually adding the module path under the **Modules \> Add Modules** option, but it still doesn’t show up.
5. Tried the link to download the compiled extension:  
`https://slicer-packages.kitware.com/catalog/All/33658/macosx` — but it’s not working.

Questions:

- Is the SlicerRadiomics extension still unavailable for macOS?
- Is there a manual installation method that works currently?
- If not, what’s the best workaround? (e.g., using PyRadiomics in Python after segmentation in Slicer?)

I’d really appreciate any help, especially if anyone has gotten this to work on a Mac recently.

Thanks so much!

> Hello! I just downloaded Slicer 5.7.0. on my Macbook “Ventura 13.2.1”. I wanted to use the SlicerRadiomics extension but I couldn’t find it. I’ve since caught up with the issue in this forum. I wanted to kindly ask if there have been any updates regarding this problem. I read that, for the time being, the best course of action was to download a previous Slicer version. However, I couldn’t access versions prior to Slicer 4 and I’ve found that these issues with SlicerRadiomics were present sin…

@hjmjohnson I see you have recently [pushed a lot](https://github.com/AIM-Harvard/pyradiomics/commits/master/?author=hjmjohnson) of maintenance related work to the `pyradiomics` project. Do you intend to also update the SlicerRadiomics extension to use the latest? Currently SlicerRadiomics specifies an old tag of `pyradiomics` (2024-01-03):
