The fix needs changes in 3 repos:

• This PR adds Mac arm64/x86_64 tarball URLs in AzureUrlUpdater (az >= 2.85.0) and sets AZ_PYTHON in Azure.java on Mac. Windows MSI untouched.
• python dependency for az on mac ide-urls#42 - az/az/dependencies.json declaring Python 3.13 as a dep.
• python default 3.13 ide-settings#86 - lowers default PYTHON_VERSION from 3.14* to 3.13.*.

Microsoft's Mac tarball needs Python 3.13 exactly it ships pre-compiled binaries built for that version, they won't load with 3.14. With the current default 3.14* and Python.java#isIgnoreSoftwareRepo=true (one Python per project), installing az on Mac fails with:

• Cannot satisfy dependency to python in version [3.13,3.14) for az@2.86.0[] since it is conflicting with configured version 3.14 and this tool does not support the software repository.

Before proposing the default change I checked:
nothing in IDEasy hardcodes 3.14, only pip has a Python dep and its range [3.8,) is satisfied by 3.13, tests pass, existing projects unaffected (they keep their own settings copy).

So 3.13 as default looks like the simplest fix that makes ide az work on Mac out of the box. But since it touches every new project - what do you think?

Verified locally on Mac arm64: ide az --version downloads tarball, installs Python 3.13, prints azure-cli 2.86.0.
