The macOS system named “computron” has been upgraded from `13.7.5` (Ventura) to `15.7.1` (Sequoia).

While we finish updating the build tools and Qt dependencies , **macOS builds of Slicer and extensions are temporarily unavailable.**

## Impacted macOS builds

| | Slicer Stable (5.8) | Slicer Preview |
| --- | --- | --- |
| Slicer Application | NA | ⏸ |
| Slicer Extensions | ⏸ | ⏸ |

_Linux and Windows dashboards are unaffected._

## Near-term plan

- We’re targeting the **Slicer 5.10** release later this week (week of **Nov 3, 2025** ).
- To stay focused on that, we will **not** restore builds of **Stable macOS extensions for Slicer 5.8**.
- Stable macOS extensions will resume **after Slicer 5.10 is released**.

Thanks for your patience and understanding 🙏

As part of this upgrade, the XCode version has also been updated? The clang version is used in the build name when viewing entries on the Slicer cDash. Computron may possibly be using clang 17?

Not yet. Once this is done, we will evaluate if a workaround like the one required when updating from 10.13 (High Sierra) to 13 (Ventura) is needed.

See [Transition of macOS Preview build from host 10.13 (High Sierra) to 13 (Ventura) - #3 by jcfr](https://discourse.slicer.org/t/transition-of-macos-preview-build-from-host-10-13-high-sierra-to-13-ventura/28668/3)

**Updates:**

- XCode has been updated to `26.1` and clang version is now `17.0.0`.

- Issue related to the build of Qt `5.15.18` should now all be sorted our and the build is in progress 🚀
