@ksimecek there is currently a bug with the version 4.7 and Apple Silicon that makes ist unusable unfortunately - tickets for that are open ([AP-19894](https://forum.knime.com/search?q=AP-19894), AP-19918). Version 5.0 seems to have similar problems for the M1 and M2 chip versions. Solution currently is to use the Intel one - and miss out on the 20%+ speed improvement …

> @ksimecek welcome to the KNIME forum. There currently seem to be some problems with the installation of extensions with the M1 / Apple Silicon version. There is already a ticket for that: AP-19894. Until it has been solved my solution is to use the ‚Rosetta‘ version. There the extensions seem to work although the splash screen at the start does not show them.
