Hello, I describe my problem with Parquet nodes (Read/Write) in KNIME on Arm64 Mac environment. In KNIME 4.6.4 or 4.7.X on Intel (with Rosetta) I have installed Big Data extensions: - KNIME Column Storage (based on Apache Parquet) - KNIME Extension for Big Data File Formats And result is I have in KNIME 4.6.4 or 4.7.X on Intel (with Rosetta) Parquet nodes, see picture. ![Knime-parquet](https://forum-cdn.knime.com/uploads/default/original/3X/2/3/238dbf12a6ee35074d42aef5edadc19c27ccc2c5.png) In KNIME 4.7.X on Arm64 I have installed Big Data extensions too, see picture: - KNIME Column Storage (based on Apache Parquet) - KNIME Extension for Big Data File Formats ![KNIME-installed_SW](https://forum-cdn.knime.com/uploads/default/original/3X/5/5/5523df3e5dc4b23ecd71d70397d4dc9294d4ac24.jpeg) But result is I have not Parquet nodes in KNIME 4.7.X on Arm64 see picture. ![KNIME-Repository](https://forum-cdn.knime.com/uploads/default/original/3X/5/c/5c5205ed4be92fc854ade006c27f5ae5ac2349cc.png) and I have errors in log, see picture. ![KNIME-Parquet-logs](https://forum-cdn.knime.com/uploads/default/original/3X/c/a/ca8297321566bb68b76611a8e837875a8673594d.png) My opinion is, that between KNIME 4.7.X on **Arm64 environment** and another KNIME environments is “some little different”, what installation of extensions do not detect as problem or do not change configuration of extensions for Arm64 environment correct.

@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 … > [@KNIME problem with Extensions on Apple M1](https://forum.knime.com/t/knime-problem-with-extensions-on-apple-m1/60266/2): > > @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. ---

Hi, We released a fix with 4.7.2 that should fix the Big Data installation on Arm64 Mac. @ksimecek can you update and verify if this helps? Cheers, Sascha ---
