How to create a .bpmn file on macOS?

A file with the .bpmn extension contains a description of a business process in BPMN (Business Process Model and Notation) format. To create such a file on macOS, you can use specialized process modeling tools, such as:

• Camunda Modeler — a free, cross-platform BPMN editor that can be downloaded from the official Camunda website.
• Signavio Process Manager — a cloud service with the ability to export in BPMN.
• bpmn.io — an online BPMN editor that allows creating and saving .bpmn files.

Example of creating a file:

1. Download and install Camunda Modeler from https://camunda.com/download/modeler/.
2. Launch the application and create a new BPMN diagram.
3. Model the process using visual elements.
4. Save the file via the "File" menu → "Save As..." with the .bpmn extension.

If you need to create a file manually, you can write XML describing the BPMN, but this is complex and not recommended without experience.
