And let’s face it, Fantastical shouldn’t have to use the faster card. But this is another application that forces a switch to the more power hungry card. Like Dropbox, Fantastical has been a staple in my menu bar. Update: Check out the response from their support. So there’s at least a way around this, which is good because this is my favorite Mac blog writing app and use it a lot. If I start Byword by opening a document, the machine uses the lower power graphics card, but if you open the iCloud open dialog box, the Discrete cards kicks in and won’t switch back until you quit the application. Update: Check out the response from Dropbox support. You start Dropbox and it instantly forces the NVIDIA GeForce GT 330M to kick in, all the time! To display an icon in the menu bar? I’m depending on Dropbox all the time, but now when I need to work on battery power I have to quit Dropbox.

Connecting a second display requires the Discrete card.

It’s been a couple of years since I did Cocoa Objective-C programming, but reading up on this problem, there are a couple of things that can trigger a switch. Why do an application switch to the power draining mode? I also excluded obvious applications that really need the extra power from the discrete graphics card. I’ve only chosen applications that I often have running in the background. Here’s a couple of applications that doesn’t need graphics power, but still kicks in the more powerful but battery draining graphics card.

So is this a bug in 10.8.3? I’ll try to test it on a Retina Macbook Pro.īattery draining applications on Macbook Pro My Macbook Pro is a model: MacBookPro6,2 and newer machines does not have the same problems. Users commenting about this sees different results than mine because of newer hardware. That’s kind of a requirement to achieve smooth effects in a Mac app these days. Using Core Animation is what will trigger the discrete GPU in this case. So it looks like this is a problem with the OS, not the developer.Īfter getting a response from the developers of Fantastical, it seems like the culprit is calls to CALayers. Newer (Retina display) Macbook Pro’s don’t have this problem. This problem looks like it’s specific to “older” Macbook Pro machines. A lot of applications forces the Macbook Pro into using the Descrete high performance battery draining card, for no apparent good reason. But there’s a snag when using Switching Mode.

The third alternative is to have it in the normal Dynamic Switching Mode.

If you need full speed, just select the Discrete card. If your on the move and on battery power, you can force the computer to use the Integrated less power draining graphics card. But how do you know which card is currently active? There is a great application available called gfxCardStatus that shows you when the computer switches, and even uses notifications. This makes it possible to use a low performance card when not using graphics intense applications, and automatically switch to the faster, but less energy efficient card if needed.

Later models of Macbook Pro computers comes with dual graphics card.

Fantastical, Growler, Hardware Grower, Scrivener and Tweetbot now works without switching cards.

Update: Just installed Mac OS X 10.8.4 and now it works much better. Better battery life Macbook Pro with gfxCardStatus
