So I traded in my 2015 map for the tb version this year and I'm having regrets. Its constantly beach balling on safari, even if its the only app open with 2 tabs. Is there a bug in safari that affects this model or something? My boyfriend was using my laptop to do homework and literally closed it and said "I'm gonna use mine instead" he has a 2014 MacBook Pro :/ lol grrr was so excited to get it and now I wanna throw it at the wall! I read about a couple of bugs and wondered is there anything I can do/fix to get it up to speed?
