I am trying to install Xcode 4 on my mac which already has Xcode 3.2.6 installed.
I searched for this and I found that I need to change the location for the directory to install Xcode, however in my case my machine has only one hard drive partition and when I try to install it on different directory there is no option available other than Developer
(the default).
So I want the exact procedure to install Xcode 4 alongside Xcode 3.
