When the Mac App Store first came out, any app that you already had downloaded onto your machine outside of the App Store was reported as “Installed.”
Apple’s made a new change to the way the MAS handled things. Now, instead of previous apps being unavailable to purchase because they are already installed, you get a warning that asks you if you want to buy the software all over again.
I still wish Apple would figure out a way to at least give devs the option of porting over their existing customer bases to the Mac App Store, but I guess this is nice: at least it warns me if I’m about to buy the same app twice.
