Hi all, additional info: I used to connect my Macmini through a Dell Docking station via USB3 (USB-C Connector, running all the following via the docking station: display connected via DisplayPort, Keyboard and mouse and LAN) since I work at home and use this docking station for both my company notebook and my Macmini. Since my last post I didn't use the docking station for my mac mini any longer and didn't encounter any issues since then... might be a hint and might also be the similarity for all of us, maybe. But hard to tell since nobody mentioned a docking station in their posts so far? Am I the only one with this scenario? I doubt it. I am sure that more people are working from home with docking stations. I will use the docking station in the next days and update again, if the problem returns... Regards AndyPie
