I don't know much about technical stuff on my mac, but today I had a huge indicator that someone is spying on my mac. There is a guy that has been very fascinated with me for a long time and I have also accepted files from him. Today, when I was going to check my email.I went to gmail.com. All of a sudden his gmail inbox opened. And he has never ever been close to my computer and he has never been to my appartment. If his email inbox opens when I type gmail.com on my computer that must mean that he is in some way on my computer no? And of course I dont have his password and have never logged into his email..... So I am wondering... what can I do? I already used mac scan on my computer, but it only found tracking cookies. This guy is a computer engineer so I guess Im dealing with someone advanced... thats why Im here..hoping to find someone advanced to help me with this problem.... what can I do about it? I have a macbook pro..Thanks in advance! xx
