"An unexpected error has occurred while trying to install. Please try again or contact customer support". I keep receiving this message when I try to install it on my macbook pro. I have the latest software, and I've diasbled and also tried enabling filevault but it keeps saying the same thing. I have not tried contacting support yet because time is important. I have the 7 day free thing and it has been activated since yesterday, and I've now already missed a day. Please, if you have had this problem, and have had it on a mac, tell me your solution.
