CPU LED is for you if you ever wonder how stressed your CPU is? Sometimes, opening a complex activity monitor while your computer is heavily loaded is too late (or too much). Sometimes all you need to know is that your CPU is working hard.

CPU LED is a very lightweight unobtrusive app that adds a LED in your status bar indicating your CPU activity (coded as light, medium or hard). You can have only one light for all your processors or one per core (your choice). You can also choose the status icon appearance so it blends nicely with your status bar style.

In order to know what is going on with your computer at more...

What's New

  • Now the four status icons are used to display CPU load.
  • Hide status icon for disabled CPU cores.
  • Fixed crash when loading a custom icon set for CPU status.
  • DiskLED addon: fixed some external devices didn't disappear when unmounted if "Ignore devices that doesn't contain any media inserted" is enabled.

Requirements

Mac OS X 10.6 or later

Funny, this tool uses about 2% CPU load on my Macbook Pro 15.

Uses 0.2% of CPU and 10.4 MB of Ram about on my MBP running OS 10.6.8. But it did just alert me to the fact that another program was using an anomalous amount of CPU -- like 100% and 2.5 times the normal RAM, so I am now quite pleased that I installed it.

This is easy to use and is back on the Mac App store so you can download it. There are loads of icon styles to choose from. The only concern is that there are only 3 levels of CPU activity: green yellow and red. It would be helpful if the way the tool would show gray for low activity since there is already a gray in the range of the sample icons. So I have to have quite a lot of CPU activity to see a change. Now I have a MacBook Air with an i& so the CPUs don't really work that hard anyway.

Enough complaining. The app is dead easy to use, is visually configurable. It is also lightweight and doesn't use any noticeable CPU cycles.

With 1.3 you now have 4 levels of CPU activity. Much more logical. No issues with it yet, and I get lots of positive comments from coworkers when they see it.

Could not download on a Snow Leopard machine. The App Store claims this requires Lion.
