By default, Macintosh OSX does not read the .bashrc file when you login to the operating system. But it does read the .bash_profile script if it does exist. Therefore, create the .bash_profile in your home directory and put this in it.
if [ -s ~/.bashrc ]; then source ~/.bashrc; fi |
Then the .bashrc file will be read and used when you login and open a terminal window. This allows the usage of custom PS1 and other useful things like aliases. This is better than typing source ~/.bashrc every time you wish to use it.

The default /etc/bashrc file for Mac OSX.

There is not much in it at all.
The /etc/bashrc_Apple_Terminal file is more comprehensive. This is good to look at, and could yield some ideas for bash scripting.
