Summary

On a fresh Mac, the system Python is 3.9.6, which is too old for runtimed (requires >=3.10). Prewarmed UV environments inherited the system Python, and conda pools specified >=3.9, causing "Environment error" failures when trying to install dependencies.

This bumps all default Python version specs to >=3.13 across conda prewarmed pools, conda env creation fallback, UV prewarmed pools (now passes --python 3.13 to uv venv), and UV inline environments.

Verification

  • On a fresh Mac (or one with only system Python 3.9), open a new notebook and confirm the kernel starts without an "Environment error"
  • Confirm prewarmed UV pool creates a venv with Python 3.13+
  • Confirm prewarmed conda pool resolves Python 3.13+

On a fresh Mac the system Python is 3.9.6, which is too old for
runtimed (requires >=3.10). Bump all default Python version specs
to >=3.13 so prewarmed pools and inline environments work out of
the box without relying on the system Python.
