Keep an Eye on Things, Live From the Dock

Do you like to know what’s going on “under the hood” of your Mac (stuff like your CPU usage, disk activity, memory usage — you know, total geek stuff)? If you do, you can keep an eye on things right from within the dock using Mac OS X’s Activity Monitor. It’s found in the Applications folder, under Utilities. Once you’ve found it, drag it into your dock, then click on it to launch it. Once it’s launched, click-and-hold for a moment on its dock icon. A menu will pop up, and you’ll see a dock icon menu item. This is where you choose which activity you want to monitor from its live dock icon. Choose it, and a live graph will appear in the dock that’s updated dynamically as you work.
