Dear SasView users, An issue regarding SasView 6.2.0 has been identified with the latest versions of macOS, where SasView experiences unpredictable behaviour which often results in crashes. This issue has specifically been reported on macOS 26.7.2, and 27.0.1. It is related to the version of QT that we use. A newer QT version will be packaged with 6.2.1. Under our testing, we believe it resolves this issue, but until that release it will still affect 6.2.0. While 6.2.1 is scheduled to release after the contributor camp, we recognise that this issue will be affecting users now on macOS. As a temporary workaround, we recommend using the PyPi distribution of SasView for those affected. If you have uv<https://docs.astral.sh/uv/getting-started/installation/> installed, the easiest thing to do is run the follow command in the terminal. uvx sasview This will automatically install SasView 6.2.0 to a Python environment, alongside the latest versions of all the dependencies. Furthermore, there are alternatives instructions available in the README file of our Github repository<https://github.com/SasView/sasview> on how to install SasView via pip. We apologise for any inconvenience caused by this. An announcement will be made to this mailing list when 6.2.1 is released. In the meantime, if you continue to experience any issues, please reply to this mailing list, or create an issue on GitHub<https://github.com/SasView/sasview/issues>. Thanks, James. -- James Crake-Merani Graduate Research Software Engineer Science & Technology Facilities Council UK Research & Innovation
