I'm new to Macs so please bear with me... I have a new 13" MacBook Pro Retina laptop. When 'Mavericks' comes out, I suppose I'll be upgrading to it. Will I see that as an option in the Mac App Store similar to how I see Mountain Lion updates? Also, I admittedly have a bootleg version of Photoshop installed to see if I'll like it and want to pay the new monthly fee they're moving towards (finally affordable?). Does all of that just transfer over to the new Mavericks OS X? I'm used to PC's and having a new version of an OS can mean backing everything up and starting all over again. Can someone please clarify some of these questions for me? Also, feel free to point out any other points you feel might help. Thanks.
