Snagit is a nice screen caputure application for Mac. Camtasia is an option if you need to record the video of your desktop screen. I am using the tool called DemoCreator which is a good screen recording software with editing features and you can export picture from any frame of the video.

Now I am using DemoCreator to make website demos and software tutorials, but it is for windows only. Another screen recorder camtasia can record the computer screen in HD, but it also for windows. But Jing Project from Camtasia is free and there is a Mac version. I have check more information about screen for Mac:
