Hello all, I tried searching "Black Box Mac" but it just came back with something different to what I have. It started around 2am this morning, and I have just turned my MBP back on to find this little rectangle shaped box is synching with everything. It shows me new tweets from Twitter for Mac, when someone is typing on Skype and then their reply and what song is now playing on Spotify and iTunes. I don't have a problem with it, I would just like to know what it is. Can anyone help?
