Hi I have recently started using Cyber Security Pro on my Mac. I get messages like this and don't know what they mean. I'm too old now to go through a full computer literacy training programme so need simple explanations. 1. How do I find out who the "remote computer belongs too" ? 2. How do I decide whether this "remote communication" is - harmful? - potentially harmful? - harmless? I can see it happen when I am "air dropping" from Mac to iPad - which I'm guessing would fall into the harmless category.....but what about others. Thank you.
