What The Fuck

MAC's CAN AND DO get viruses. So for the folks saying they don't- you're flat out wrong.

I found it pretty obvious when you described the situation.. it's a RAT. A person who has you ratted can watch your screen and they can also keylog you through the rat.

I guarantee he was watching you for a long time, then struck when the time was right. If you ever typed in your pin, he saw the whole thing.

RAT's can lay dormant for a long time, and never ever get picked up by an anti virus.

It's shitty people have to resort to hacking others', and dropping your rapier is even worse. Sorry for your loss.
