Sidekick for Mac

From Oomph:

Sidekick is an application that automatically updates your laptop settings based on where you are. Just install the app, configure the places that you frequent, (home, work, a coffee shop, etc.) and never fuss with your settings again. Sidekick performs different actions each time you move your laptop to a new location. You can set up all kinds of actions such as adjusting your volume, or configuring your default printer. Places represent the different computing environments in your life. Sidekick understands that the way you use your laptop at home is different than at work, school, on an airplane, or in a coffee shop. Sidekick recognizes your location and configures your laptop accordingly. Sidekick is even more configurable with a variety of free plugins for your favourite apps. You can even build your own plugins.
