i just bought a new macbook pro 15" yesterday (the last one in the store, lucky me) and i installed the hard drive that was on my old macbook and put it on this one, and bc it had snow leopard on it i was forced to upgrade to mavericks to get it to work on my new macbook. well mavericks sucks. I'm having so many bugs. safari wants to crash every single time i open it. my plugins don't work and i can't open tabs or new windows in safari. i hate most of the features except being able to open tabs in finder. but is it possible to downgrade back to mountain lion? would it work ok?
