**Internal ticket ID:** AP-24214 **Summary:** Bundled Python Conda environments do not work on MacOS 15.4 **Fix version(s):** 5.4.4, 5.5.0 **Other related topic(s):** > [@KNIME Labs: Troubles with some 'Items' - e.g. 'KNIME AI Extension' - on Mac](https://forum.knime.com/t/87483): > > Hi, I’m running Knime 5.4.3 - with all Extensions - on a MacBook (M3). After upgrading to a newer OS - macOS Sequoia v15.4 - I noticed a series of Warnings/Errors (see below) at start-up and could not find the ‘AI’ package in the ‘KNIME Labs’ anymore. So I decided to go for a fresh installation of KNIME 5.4.3 and the base istallation (without extension) showed no Warnings/Errors in the Console at start-up. Installing the complete ‘KNIME Labs Extension’ worked (no errors during installation)… > [@Can't install KNIME AI Extension](https://forum.knime.com/t/87566): > > Hi,Knimer When re-install knime 5.4.3, the local GPT4ALL node was missing. After uninstall KNIME AI Extension, then re-install AI Extension again. It still can’t solve this issue. How to fix it? Cannot complete the request. See the error log for details. "KNIME AI Extension" will be ignored because it is already installed.``` --- _[View the full topic](https://forum.knime.com/t/execution-failed-could-not-connect-to-the-python-process/87572)._
