If you’ve ever used Safari with the Flash plugin to browse the web, then you know what can happen. Websites filled with Flash ads begin to suck up your Mac’s CPU, which start the fan spinning, and the battery. You can open up Activity Monitor to see what’s happened to wayward apps, but the process to find and force quit a resource hogging app is cumbersome at best.
Instead, try using System Lens. It’s a Menubar app which gives you a one click look at which of the open apps are using the Mac’s CPU the most. Instead of worrying about which apps is using how many threads or how much real memory or what percentage of the CPU, System lens makes it easy to find the bad app and kill it dead.
Click the System Lens icon in the Menubar for a resource snapshot.
While it’s ready to run right after installing, it does come with a few Preferences to give you more control.
The real fun begins in the Advanced Options and filters where you can set and customize threshold options using the slider bars. This is especially useful if your Mac has limited RAM and an older, slower hard disk drive.
That’s it. No gobbledygook to decipher. If an app is in the red and the fan is blaring and the Mac has slowed to a crawl you’ll know the culprit right away and force quit is merely a click away.
