I'm working on an Xcode project and my brother wants to start helping out. I have the .git folder in my Xcode project directory, how can my brother pull / push / commit to / from my computer? Do I have to use OS X server and put the repo inside of there, or is there a simpler way to do this?
One simple option is to enable "remote login" in sharing, which enables ssh, then you can use the ssh protocol to clone the repository. Remote login preferences will tell you:
To log in to this computer remotely, type "ssh username@computer.local".
username@computer.local will be replaced with your username and hostname. In terminal, use:
git clone username@computer.local:[path]
on your brothers computer to clone the repo to him, where [path] is the path to the folder containing the repository. You will need to enter your password, and you will need to enter it in order to copy changes back later with git push or whatever.
You can set up passwordless ssh with private keys, but bear in mind that by doing this you are effectively giving your brother entire control of your computer.
