The main decider is whether your issue is Hardware-Related, because that is the main expertise of the Genius Bar technicians.
Genius Bar technicians are really good at working on Mac Hardware. They put their hands on these machines all day every day. MacOS and software issues? Not so much.
Appointments were stretching out in the future for many weeks. Too many. So Apple decided that they needed to refine exactly what issues are candidates for Genius Bar.
If you followed the questions and read the articles, Software-Related issues will NOT lead you a Genius Bar appointment, because it would waste your time and the technician would not be able to help you.
