Upgrade vs New
I have a 2009 Yosemine 10.5 MacBook Pro which I passed to my daughter (11) to work on her distance learning schooling. I beginning to think how reliable will it be for her and if I should consider giving it an upgrade or should I just buy a new one instead? It looks to be doing the job for her, but I noticed a couple of "hick-ups" If the upgrade is worth doing and taking in consideration that I am not confident on how to do it right, who can help me do it correctly? Or who can do it for me?
MacBook Pro 15″, OS X 10.10
