It works with the mentioned version too. But after I successfully installed Xcode on my machine and rebooted it, there is no XCode link created at all in the Applications folder. I have to run the downloaded dmg file again to see it popping up. But later it'd disappear once I power of my machine. Is there a solution to this tiny problem ?
Edit: it seems I don't understand about the difference between the dmg file of size 1.98GB and another one of size 1.4GB, i guess this is probably the problem. I downloaded and installed 1.98GB dmg and it stays as a separate disk image the second time I run it.
