hi, I am pretty new to mac and I have a big problem: Someone I cannot trust had access to my MacBook and I saw him entering code in whatever is the mac equivalent to dos, I guess. He said he needed to see my IP address so I could get on their network, because I can only get on if he adds my computer. It seems fishy to me but either way, the guy is way good with computers, but I have good reasons to mistrust him. I obviously have my Firewall on and opted out of all file sharing. I also installed Little Snitch, but there are some files I am not sure whether they should be there, especially "Mount_nfs". Should that file have access? Would a system restore set eliminate a change? Would just cleaning the whole computer and starting over solve the problem?
I'd be really thankful if someone could tell me what I can do?
Thanks
