Suddenly, the Mac’s fan begins to roar. You switch over to another app or two and your Mac seems to have slowed to a crawl. What’s going on?
Restarting your Mac usually clears up such problems but they’re annoying nonetheless. Here’s a quick, easy, and free way to check on your Mac’s system status from the Menubar, and avoid the need to open up Activity Monitor to figure out what’s going on. The app is called System Lens and it’s free.
Click System Lens in the Menubar and here’s what you get. A simple, straightforward view of which apps are using the most of your Mac’s limited resources.
If an app gets all wonky and starts sucking up CPU juice, or the fan comes on so loud you’re afraid it might wake the neighbors, you can close the app right from within System Lens.
The Menubar icon updates regularly to display usage. And, you can set up custom usage thresholds in preferences. System Lens isn’t as geeky as OS X’s built-in Activity Monitor app, but not as confusing, either.
Most of the time a single click gives you what you need to know. Lots of four and five star reviews for this one.
