What’s going on? The likely culprit– the one that drains battery and heats up the CPU which causes the fan to come on which drains the battery even more– is usually a wayward app that needs to be tamed before it causes you even more grief.
How can you tame wayward apps? With App Tamer. Seriously. That’s the name of this Mac utility. App Tamer. A whole bunch of things start to happen when a Mac apps decides to misbehave. It starts a cascade effect which takes CPU away from the app you’re using, draining the battery faster and heating up, which then causes the fans to come on to cool things down, which drains battery even more.
App Tamer watches Mac apps from the background and does a few tricks to keep them from becoming delinquent troublemakers. It can automatically slow down or pause apps in the background, the ones you’re not using at the moment. That reduces CPU usage, and limits how much battery life they can consume by their wayward lifestyle.
Click the App Tamer icon in the Mac’s Menubar and get a list of the running apps sorted by how much of the CPU they’re using.
You’ll see exactly which app is causing what kind of trouble, as well as a list of all apps running on your Mac, and which apps are being managed by App Tamer.
Out of the box, App Tamer automatically reduces CPU and battery usage of the most used Mac apps– Safari, Firefox, Google Chrome, Spotlight, Time Machine, Illustrator and Photoshop, as well as Microsoft Word and others.
However, you can choose which specific apps for App Tamer to manager, and you have control over the details, so customization options are your friend. Does all this frugality make a difference? Yes. Controlling apps and CPU usage, and saving as little as 10-percent, can add an extra hour to your Mac’s battery life.
Not every Mac user needs App Tamer, but if your fan is coming on all too often, and the Mac’s battery life seems to dissipate too quickly, this app is a good way to gain back a little more control and power.
