Microsoft provides a free viewer that runs on Microsoft Windows systems for files created by its Visio diagramming and vector graphics application. But it does not provide a viewer for systems running Apple's OS X operating system. VSD Viewer Pro from LawBox LLC provides a good, low-cost means to view the .vsd and .vsdx files produced by Visio on Mac OS X systems. The developer's webpage for the application is at VSD Viewer Pro for Mac. The current release, VSD Viewer Pro 1.2, is compatible with OS X Mavericks 10.9 or later for systems with a 64-bit processor.
The software can be obtained using the Mac App Store application on OS X systems. The current cost is $4.99 USD.
