For a quick inspection, MeVisLab users may exploit the Quick Look functionality of macOS to inspect Network (.mlab), Scripting (.script), Definition (.def), and License (.dat) documents (Figure 2.3, “Take a Quick Look of MeVisLab networks on macOS”).

Figure 2.3. Take a Quick Look of MeVisLab networks on macOS

The Quick Look previews of MeVisLab Network documents are stored in the resource fork of the Network files and thus do not affect the loading of Network documents in any form. Only Network Documents that have been saved with the MeVisLab macOS edition running on macOS 10.5 or better provide a preview image. Besides Quick Look, the previews will also show up in Finder or on the Desktop if you choose so.
