Stopped working. The pro version does not run on either MacBook Pro macOS Big 11.7.3 (20G1113) or Windows 10. Also, while it was running, all projects took a long time to load and freeze at 50.75%. I see a lot of people writing about it. The process of rendering copper polygons takes forever and there were also freezes at this moment. Very inconvenient without the usual copy, paste and the like, which is called through the right mouse button. When searching for components, if it is not available, then it cannot be put into the circuit. How does stock availability affect this? I can order the component elsewhere.
