Note: One of our Macintosh customers experimented and figured out a way to view MrSID files on Mac platforms. He provied installation instructions. If you understand them and want to give it a try, that is great but we do not support Macintosh for MrSID files so we cannot provide assistance.
Here is what he did:
- Install Xquartz - http://xquartz.macosforge.org/landing/
- Install your viewer. He chose to use TNTAtlas - http://www.microimages.com/products/tntatlas/ and that seems a good full featured choice to use for this purpose. He also made a note that such things like drag and drop don't work so you have to actually use the open function from within the program to access the files.
DJVU Viewers:
Our DJVU products work on both Windows and Macintosh platforms.
