block texts on messages mountain lion
So I love the messages app on my MacBook but I have recently become a victim of sexual harassment from a guy who I used to know and because he used to be a friendly, nice, and intelligent human, he has my cell number. This unfortunately means, because he is using iMessanger to send obscene messages to me, that they also show up on my laptop. I have blocked him on my iPhone through my cell carrier but I have yet to find a way to block just his number on my laptop. Ideas? Anything is welcome at this point, thank you!
MacBook Pro, OS X Mountain Lion (10.8.4)
