MeVisLab 3.5 for macOS requires macOS 10.15 (Catalina) or later.

MeVisLab is distributed as a macOS disk image (dmg). Before opening the disk image, the license agreement is displayed. Please read the license agreement carefully before accepting it (Figure 1.1, “License agreement”).

Besides the MeVisLab application and full Software Development Kit (SDK), the distribution contains the MeVisLab User’s Guide of the macOS Edition and the license document.

The distribution also includes a README file with up-to-date installation instructions and requirements, please review both before installing and starting MeVisLab (Figure 1.2, “Contents of the distribution disk image displayed in Finder”).

MeVisLab is built as a self-contained application bundle and may be installed in a directory of your choice. The recommended installation location, however, is within the user or system-wide Applications folder (~/Applications or /Applications, where ’~’ is your home directory).

You may now proceed to set up the preferences for external default applications, such as your favorite text editor or web browser. This is done within MeVisLab via the Preferences panel (available via menu MeVisLab › → Preferences… › → Supportive Programs). To use the macOS default application for a document type or scheme, leave the text field empty (Figure 1.3, “MeVisLab Preferences panel”).

Congratulations, you may now start using MeVisLab. If you would like to extend the functionality of MeVisLab by developing your own MeVisLab modules, please proceed to Chapter 5, Module Development.
