There are many screen-capture applications for Mac like Skitch, but Mac users have long been waiting for a screenshot app for Mac, which match the capabilities of SnagIt for Windows. SnagIt is basically a screen-capture application program, that creates an image of what you see on your computer monitor.
SnagIt for Windows, is undoubtedly the most advanced and user-friendly screen-capture software application. SnagIt has officially unveiled the Beta version of SnagIt, for taking screenshots on a Mac. The interface is very different from the Windows counterpart, but that is understandable considering that the Windows version uses the Office 2007 Ribbon UI that Microsoft has not made available for Mac applications.
You can download free Beta version of SnagIt for Mac from here.
It offers an all-in-one capture mode that tries to detect whether you want to grab the full screen, a window, a specific region, or even a scrolling area. Many small things are worth appreciating, like the small magnified window when capturing a region. The awesome thing about the magnified window is that it does not actually appear until your cursor isn’t moving much on the screen. That makes sense because when your cursor is only moving a few pixels at a time is when you are probably trying to get a pixel-perfect screenshot, and that is when you need the magnified area.
Overall, there are a lot of nice touches in the app. You can use keyboard shortcuts, the Menubar icon, or the hide-away window to initiate a capture. SnagIt for Mac is not full-featured yet though, and you will notice that as soon as you click on the Effectstab where all you will see is a Coming soonmessage. The things that are available work very well though.
