OS X 10.5.8 to current version?
I have a MacBook Air that's running OS X 10.5.8 how do I get to the most current version of OS? Everything I look at says through the App Store. I don't even have that on this machine and I think I need to be on 10.6.x to get it. Help?
Thanks!
MacBook Air, Mac OS X (10.5.8)
