- Booting MacMini in safe mode solves the problem
- Turning off every startup item and then booting normal: the problem reapears
- NOTE: During the first few seconds after boot up I can successfully ping and ssh and then it starts failing. Which implies that something at that point in the boot sequence causes the problem
Next Steps?
- Any suggestion on how to identify what is causing the problem
