Came here to say this. It's an amazing tool. Set it as your git difftool and it will change your life. I switched to Mac about 8 years ago and ran it in Wine for a long long time until they finally released a Mac version. Their diff algorithm is so damn perfect no other diff tool compares, and I've tried SOO MANY. It lives up to its name. It's an amazing tool that's crossed platforms with me, and I'd rather give up my left hand.
