New Mac couldnt install AI Extensions

Hi KNIME Community,

I’m having trouble using the KNIME AI Extension on macOS 15.4.

Steps I already tried:

• Clean reinstall of KNIME 5.4.3 (including workspace and library cleanup)

• Moved KNIME into `/Applications`

• Ran `-clean -initialize`

• Applied the fixknimepython_envs.sh script

Still, the AI Extension is reported as “already installed” but doesn’t show up in KNIME (AI nodes are greyed out).

Is there an official fix for this on macOS 15.4?

Thanks for any help!

Best,

Philipp
