Austin Silver Software is proud to announce the availability of McDwiff, a DWF viewer for the Macintosh:
McDwiff requires an active internet connection. It connects to Project Freewheel to render the DWF files 100% accurately. You can open any DWF (2D or 3D) on your Mac, just like any other file type. 3D files open, but 3D rotation will be coming in a future version. McDwiff requires Mac OS X 10.3.8 or later. It runs on both PowerPC and Intel Macs. McDwiff is free for non-commercial use and $39 otherwise.
Although not quite the equivalent of the Autodesk DWF Viewer due to its use of an internet connection and the uploading of design data to an Autodesk server, McDwiff is a huge step forward in enhancing the DWF experience for Macintosh users. There might be some interest in this. One or two people have asked for a Macintosh DWF viewer. :-) This is another example of DWF going beyond the paper.
