4D v19 applications are able to run on Apple Silicon (M1) Macs via Rosetta. After compiling a 4D application for Intel/AMD, you may encounter an error when trying to run the app on M1: “Can’t open packed project [name] because it contains no valid compiled code nor source code.”

To bypass this error and force the app to run with Rosetta, right click on the app and select “Get Info” in the context menu. Then, under “General”, toggle on the “Open using Rosetta” setting.



Now, the application will launch with Rosetta when opened.
