Hi. I was wondering this: Hypothetically speaking, what would happen when the final Mavericks version is released to the general public if someone had downloaded and installed Mavericks (seeded for developers only) without being a developer? I mean, would he just have to pay? Or could he just keep on using it without any payment? Would the OS deactivate or something? Would it downgrade to previous version before the final release is coming out? Thanks for your help.
