You are not running the real "git" at all here; Apple ships stubs for
several commands, including git, that are distributed with XCode. When
you run the program, it prompts you to install XCode, which then
actually downloads and installs git, replacing the stub.

You can download XCode separately, of course, but you would still need
to agree to the license. You can download git separately and not need to
bother (though I do not know offhand how to download Apple's git, or
whether they provide a script to replace the stubs).

Also, minor nit, but git is GPL, not LGPL.

You can always download and install git yourself. There's no need to use
the XCode version. However, XCode is the simplest way to get a compiler
on the machine, AFAIK (I do not use OS X myself).

You didn't run a derivative git. You ran their stub.

As it happens, though, they _do_ modify the git that they distribute. I
know at least that they bake-in the osxkeychain helper config in away
that the user cannot turn off. There may be more changes, but I haven't
done a full diff. And they do provide the source:
