yEd
yEd is a desktop diagram editor from yWorks for creating flowcharts, UML, network maps, and other graph-based diagrams on macOS.
What is yEd?
yEd is a desktop graph and diagram editor published by yWorks GmbH. It is used to create structured visual diagrams such as flowcharts, UML diagrams, BPMN diagrams, entity-relationship models, mind maps, and network layouts. A key part of the app is its automatic layout engine, which can rearrange complex node-and-edge diagrams into clearer views with minimal manual work. On macOS, users typically encounter it as a standalone diagramming tool for technical documentation, planning, analysis, and presentations. yEd supports manual editing as well as importing external data and saving diagrams in GraphML, with export options for sharing or printing. It is a legitimate end-user application and not a system component, so its presence usually means someone intentionally installed it for diagramming work.

Safety overview
Status: Safe
yEd is a legitimate diagramming application from yWorks GmbH. It is generally safe when obtained from the official yWorks website. The main risk is normal document handling: imported files or downloaded diagrams may contain unwanted content or misleading data, so use trusted sources for files you open.
Recommendation: Keep it if you use it for diagramming, graph editing, or technical documentation. If you do not use yEd anymore, removing the app is usually optional and should not affect macOS itself, though you may also want to remove any remaining yEd support files if present.
