You could have downloaded TabMate 1.7.6 for Mac from our software library for free. The program lies within Developer Tools, more precisely Webmaster Tools. This Mac application was originally created by CosCulture.
From the developer:
TabMate 2 is a new RapidWeaver stack that lets you easily add tabs in your web pages. With tabs, you can organize your content in a neat and accessible manner. When viewed on a mobile device, the tabs become an accordion so your content looks good on different devices.
