Question: I just upgraded my Mac to [Mac OS X v10.7](https://en.wikipedia.org/wiki/Mac_OS_X_Lion) (Lion), and now Git is gone:

```
$ git
-bash: git: command not found

```

How can I get Git back?

Answer: 
It's part of [Xcode](https://en.wikipedia.org/wiki/Xcode). You'll need to reinstall the developer tools.
You can always use [MacPorts](http://www.macports.org/install.php)...
