When I run
git --version I get
git version 184.108.40.206 (Apple Git-37), and it seems to be located at
/usr/bin/git. I don't remember installing Git, but I did install Command Line Tools for Xcode in order to install Homebrew. Not a full Xcode install — just the command line tools.
I'm trying to figure out how best to update to a newer Git version, and determining how it was originally installed would be helpful. I think it came with the command line tools installation, but I'm not 100%.
