Okay, I have no clue where to put this but i just need help. So I got a new laptop, the macbook pro. I had an apple before but I was wandering around on here and this app got opened. only problem is I don't know how to close it, and it won't shut up. It is this black bar that tells me everything I do and every time I go o a site it has to point out everything and won't let me scroll down. I might be able to shut it down if I knew what it was called. could someone please help!
