Hey guys, sorry if this has been asked before but am sort of confused here. I'm currently running OS X 10.7.5 and have been intending to upgrade to Mountain Lion for some time. Now that Mavericks is out as the 'improved mountain lion" so to speak, for free, I was wondering this. If I install mavericks while currently running 10.7.5 will I get mountain lion as well for free? Or will it simply **** up my Snow Leopard Install? Should I buy mountain lion first, upgrade to 10.8, and then install mavericks? Thanks so much!
