TNTatlas is a free and cross-platform application that allows you to view hierarchical atlases prepared in TNTmips with HyperIndex Linker.
Moreover, you will be able to publish spatial information for wide-scale, multi-platform distribution. You can also create stacks of relational imagery, drawings, databases and maps that can be used anywhere.
Detailed instructions on how to use the TNTatlas utility on your Mac are available HERE.
TNTatlas is cross-platform and it works on Mac OS X and Windows. Binaries for the Windows platform are available on the project's homepage.
