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.

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.

Works well, but has some issues

On my Retina MacBook Pro with 10.7.4, the App itself works great, I see notifications at login and other notifications as things happen to change, drives being mounted & unmounted (like when Google Chrome is doing a self update) for example. I am not seeing and have not seen the other issues reported here about power and IP notifications which *could* be due to bugs in the App, but could also be a sign of a power cable that is starting to fail or a hardware router with bad DHCP settings (which could cause IPs to expire and be reacquired frequently).

I do however see apparent signs that HardwareGrowler 1.3.2 (or Growl 1.4) has a significant memory leak. I have iStat Menus installed which show me that HardwareGrowler uses up to 1+ GB over time. Logging out and presumably quitting HardwareGrowler causes the memory value to reset. Hopefully this will be addressed by the Developer eventually. A memory leak *could* be the root cause of some of the other issues reported here.

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.
