To open "Datamodeler.app", you need to install Rosetta. Do you want to install it now?

No I do not.

There are two solutions:

• Start the datamodeler by running the “./Datamodeler.app/Content/MacOS/datamodeler.sh”

This is what I did for a couple of moths. Cumbersome, but it works! I created a “.command” file in the /Applications folder, so I could double-click that to start the datamodler.

The downside of course is that it will also start a terminal window. This must be closed manually after use of the modeler.

• Start the modeler with a double-click as we’re used to

For this you need to right click the Datamodeler.app file:

uncheck the “Open using Rosetta” tick-box.

You’re done.
