Set up a new Mac

Install the Xcode Tools

When trying to run a command such as git, your Mac will tell you Xcode tools are not installed yet. A pop up dialog will display, you just have to click on 'Install'.

Or if you prefer, you can run:

$ xcode-select --install

Configure git

Create a .gitconfig file in your home directory with the content in this Gist

Copy and paste the files .git-prompt.sh and .git-completion.bash from this Gist into your home directory.

Add a global .gitignore to your home directory, following Github's advice. This Gist has an example in file .gitignore_global.

Configure your terminal

Add aliases, autocompletion and so on. This is done by creating a .bash_profile file at your home directory. Take the example in this gist.

# in your home directory
$ nano .bash_profile
# paste all the content of the file, save and quit

Select the Pro skin with 93% of opacity 🎨. The nice colors of prompt and so forth are already added by the .bash_profile settings.

Install all the dependencies for your terminal

When starting up a terminal session, it will load the .bash_profile which has instructions to try and load some environment variable, libraries and such. If you don't install these libraries, an error message will be displayed.
