I really like the MacBook magnetic Power connector, but sometimes I do not notice when it disconnects. This tip helps make disconnects and connects noticeable when a charging change occurs. This tip requires that you install Proxi, which is a free app from Griffin Technology; download it from this page.

Once installed, here's how to create an alert to monitor your power connector:

  1. Launch Proxi and open an Editor window (if it is not already open).
  2. At the bottom of the Triggers column, click on the Gear menu » Insert Trigger, and select Battery Monitor. This will add a Battery Monitor line to the Triggers column; select it.
  3. In the Settings column, where it says Trigger If, select Power Source and Changes to Battery.
  4. In the Tasks column, click on the Gear at the bottom and select Play Sound. In the Settings column, select Submarine (or other sound of your choice).
Repeat these steps to add a second battery monitor to run when the battery starts charging again. I like the Frog Chirp sound for the connect. Finally, add Proxi to your Startup Items so it will run every time you reboot your computer.

[robg adds: A couple of other options for monitoring the power supply connection are Unplugged, and (my personal choice) Growl plus the HardwareGrowler, which can monitor a lot of other hardware-related changes as well. I'm sure there are more out there...]
