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) - but at start-up, the Warnings/Errors showed up again (see below, the first lines of the log)! Is there any known Problem with this OS Version for Mac? Thx!

Root Cause Some Conda libraries—particularly libgfortran (used by numpy)—contain duplicate RPATH entries, causing them to fail to load on macOS 15.4. This is not limited to KNIME; it stems from a known problem in the numpy conda-forge feedstock ( https://github.com/conda-forge/numpy-feedstock/issues/347 ), and a permanent fix is not yet available.
