My mac is completely blocked because of a pop up that doesn't let me open any app or safari's page. What do i have to do?!?!
I was on the internet playing a game them suddenly a pop up page came on and i pressed the "x" at the top to exit (like i always do) than the page askes me "are you sure you want to leave this page?" The text after this is so long that i can't say "leave this page" i tried to open other apps or pages but it tells me that i have to leave this page. I have no idea what to do. I can't even turn off the computer because it tells me that before i have to leave the safari... Please help!!!
