Does that mean only Mac with Lion installed can get Xcode 4.1 for free? what about Snow Leopard? No more hope?
4.1 is for Lion, 4.0.x is snow leopard.
I had problems installing 4.1 also. After download and an immediate install (as in instant, which was weird), it turns out it never really installed. I had to manually uninstall my old Xcode and go into applications and click install XCode. Then it worked perfectly
