Even though Apple doesn’t natively support it, window snapping is available on the Mac via a variety of third-party apps.
This feature was first popularized by Microsoft’s Aero Snap on Windows. Window snapping allows you to position windows in specific areas of the screen, usually by dragging the window to the edge of the screen, causing the window to “snap” into place. Afterwards, I received several tweets and emails asking how to perform window snapping, since this is not a feature that appears natively in OS X.
Yesterday, we wrote a post about, and in the corresponding video tutorial, we used window snapping to highlight one of the benefits of a hidden menu bar.
