SUMMARY

On macOS, Kdenlive embeds its own Python interpreter (Python 3.9.6).
When attempting to install the Object Detection / Install Missing Dependencies, installation fails because the sam-2 package requires Python ≥ 3.10.

There is no setting in the macOS build to select or override the Python executable. Kdenlive always creates its virtual environments using the embedded Python 3.9.6, making it impossible to install SAM2 on macOS.

As a result, Object Detection is currently unusable on macOS.


STEPS TO REPRODUCE
1.  Settings → Plugins → Object Detection
2. Click Install missing dependencies button

OBSERVED RESULT

In log getting:
ERROR: Package 'sam-2' requires a different Python: 3.9.6 not in '>=3.10.0'

EXPECTED RESULT


SOFTWARE/OS VERSIONS
macOS: 14.7.2 (23H311)
