[FRQ]

I download yosemite on MacBook Pro , I upgrade it , everything was going wel, i think at end Of process on page " terms and conditions " agree or go back option is not working .anybody know about it ?

You could try scrolling to the bottom of the terms, but I didn't have to.

Just hit back and cancel it to start again.
