My wife may think of me as a collector of digital tools. Why? My Mac has a few hundred apps, some of which belong in the One Trick Pony Parade. They do one thing, and not much else, yet they’re useful enough to keep around, and they’re priced right. In the case of PixelWindows and CPU LED, they’re even free.
First up is PixelWindow. Use it to measure items on your Mac’s screen in pixels. The transparent window can be moved anywhere on the screen to measure a graphic, webpage, design, or anything you can see.
Does PixelWindow do anything else? Not really. It can be resized onscreen to measure anything you can see on the screen, but it’s a true one-trick-pony app. You may not use it often, but when you need you need it.
Second up is CPU LED which I use all the time. It doesn’t do much, either, but it does it all the time. Literally. CPU LED is a small meter app that lives in the Mac’s Menubar. All it does is monitor your Mac’s CPU.
Green means the CPU isn’t working hard. Red means it’s working very hard, In between is amber, which displays a CPU that’s working but not overloaded.
At least it’s configurable.
There’s a reason that CPU LED is free. It’s a gateway app. From within CPU LED you can spend a few dollars on Memory LED, or Disk LED. Can you guess what those do?
