My teenage son did this. Going to the Apple Store today.
Oh no, I hope you get it fixed.
Sorry to hear that...my response if my son fell for this trick...
He’d be sitting and staring at a “brick” for quite a while until he figured it out.
He’s already been warned about the idiots and saboteurs of the www...he learned his first lesson on sidebar ads when he got the FBI virus for clicking on some game link...I didn’t bail him out for quite a few days until he actually needed the laptop for school.
