I've tried lot's of c++ IDEs on MacOS X, but none of them is as powerful as VS Studio on Windows. It's always hard for me to choose an IDE before I want to write some code, as it's called the Selection phobia. Generally we have the following choose:

• Vim/Emacs (I'm familiar with VIM but it's still not an easy way, for me)

• CodeLite (it's a good choose!)
• XCode (I just don't like it, Heavy and ugly, can't get used to it)
