publishing iphone app to app store is no more possible from 10.6.8 and xcode 4.2 ? my app gets rejected after successful submit. I need to get an confirmation so that i can plan if i need to migrate to 10.8.*
My understanding is that Mavericks is just plain and simply free. That would mean you don't need anything to upgrade from. You could buy ANY hardware that supports it and install it.
I don't know if it's an 'upgrade' in terms for requiring a certain prior version of OSX.
Some OSs use 'Upgrade' vs 'Full' versions, this should be in the Mavericks requirements documentation.
I've heard that the latest Xcode requires Mavericks... that's why I'm working on moving from ML to Mavericks.
