MockupScreens (http://mockupscreens.com) has released MockupScreens 4.26, an update of the software for creating screen mockups of applications and web page sketches. The new version is Mac OS X compatible.
MockupScreens was originally developed to facilitate communication between developers and customers by presenting visual examples of what an application or a web page will look like. However, the earlier versions didn’t support operating systems other than Windows, and Mac users could create mockup screens only via virtual machines.
Now a Mac version of MockupScreens is available, and it’s not just a clone of a Windows version, but a full-fledged Mac product, says Igor Jese, the author of MockupScreens. A single-user license starts from US$99.95. Every customer is guaranteed one year of free upgrades and free e-mail support. Licenses are interchangeable among Mac and Windows systems. A demo is available for download.
