Git Config Error in Xcode

As asked and answered on stackoverflow, there's an easier way to do this that doesn't involve making a new file system in a disk image file:

Move your existing file aside, commit that move, then move it back using the case you'd like it to maintain and commit. Done.

Example:

mv foo foo2
git add -A
git commit -m "renaming"
mv foo2 FOO
git add -A
git commit --amend -m "renamed foo to FOO"

Confirming couple of points

1. You are running OSX 10.6.8
2. Current Xcode version in your machine is 3.2.4

Xcode 4.2 should work fine on your machine. I have a snowleopard machine at office running Xcode 4.2, i updated it via the Mac App store only. Ok. If this is not working via Mac App store, then go to your developer account (free or paid) and then download the Xcode version for Snow Leopard and install it manually. Just make sure you are downloading the Snow Leopard edition not the Lion edition. Please don't hesitate to ask for assistance :-)

Edit : Here i am attaching a snapshot of where to find the link . You need to scroll down and check in the Downloads section.
