I had visited a friend of mine recently and used his MBP. And, I happened to stumble upon an alphabet – d – on his menu bar. Having so much love for those tiny – yet powerful – menu bar apps, I asked him about the app.
Before he could finish explaining (It took less than a minute!), I found myself already searching for the app. Meet – gfxCardStatus – a free, open source app that helps you to switch GPU, aka Graphics Card,at your will. Its for 15″ and 17″ MBP’s from late 2008 and until the retina MBP’s (The reason is very obvious). Its updated to Mountain Lion as well.
Off late the Macbook Pro’s come with dual graphics card and they switch automatically based on the app you run. But, most of times we are never aware of which GPU you are running on. And even if you knew, we hardly knew which app kicks on the integrated Card. And this app helps you will all of those. You always need to understand you laptop to get the best out of it!
UI:
As you expect from any menu bar app, its got the basic option – About, Check for Update and Preferences
