HardwareGrowler is the best way to find out when hardware status changes on the Mac. If you need to know what's going on with your Mac, then you need HardwareGrowler.

When your power cable unplugs, HardwareGrowler will spring into action and lets you know about it. Plug in a device like a keyboard, thumb drive, or even a usb headset and get notified about the hardware changes.

HardwareGrowler will also let you know about changes to networking on your Mac. When a wireless connection changes to a different access point or an IP address changes, you'll be notified about the change.

HardwareGrowler is what you need if you need to know about your hardware. HardwareGrowler uses Growl to provide notifications or can do it all by itself. Simple to use, easy to configure, HardwareGrowler is the application for those who need to know.

No update in Year and a Half

With all of these reviews crying out for extra functionality, you’d think that more would be forthcoming with this app, but no. It notifies me 10 times a day that bonjour is running! The old one is free. The group gets some money and you figure it would be better now but It’s just Ok for the money.

Good, but need Bluetooth LE filtering

Great app. I have used it for years and was happy to pay for it when it moved to a paid model. One thing it could really use, though, is a separate filter for Bluetooth LE connections & disconnections. They happen almost constantly and don’t really help me understand the state of my machine. Even better would be a general (cross-module) string- or regular expression- based filter. In the mean time, I’ve had to completely disable the Bluetooth module, which is disappointing.

This application is worthless, no documentation on it use. It appears that this app has not been updated in years. What little documentation I could locate appears to be related to a very old version 1.2 from numerious years ago. The open window function under the notification doesn't work and the notification disappears from the notification section within 30-60 seconds of being clicked on. The support link takes you to a site that tries to sell you other apps. Save your money
