workaround for severe screen sharing bug in Mavericks

Category skype
I love my MacBook Pro... once you go Mac, you never go back. Unfortunately, there's a massive problem with screen sharing once you've upgraded to Mavericks: models that have both an "integrated" (low-power) and a "discrete" (high-power) video card started using a feature that Apple calls "Dynamic Switching". This feature attempts to maximize battery life and other aspects of OSX performance by toggling between the display modes depending upon what you're trying to do at the time. As a rule, you don't notice when this is happening... "it just works".

...until you try to share your screen via Skype, GoToMeeting, join.me, etc. Within a few minutes (although the actual duration is unpredictable), you'll either be logged out of OSX without warning, or your entire screen will lock up; in the latter scenario, you can still talk to other meeting participants — you can hear them, they can hear you — but suddenly your mouse isn't moving anymore, and the only way to get back to normal operation is to hold the power button until the machine shuts down.

In my current job, I spend a significant amount of time sharing my screen with coworkers and customers. As you can imagine, this bug was extremely frustrating for me... until I found gfxCardStatus.

This simple utility adds an icon menu to the OSX menu bar, allowing me to change from "Dynamic Switching" to "Integrated Only". Now I can share my screen without incident, and I'm back to loving my Mac.
