MetadataMagic 2.0 for Mac was available to download from the developer's website when we last checked. We cannot confirm if there is a free download of this app available. The software is categorized as Business Tools. We recommend checking the downloaded files with any free antivirus.
From the developer:
MetadataMagic reads the metadata (all of the information about the layouts, fields, scripts, value lists, relationships, etc.) directly out of your FileMaker files and populates it into an easy to use FileMaker database. It can process an unlimited number of files (no 50-file limit) and you can navigate through your interrelated metadata with unlimited drill-down and go back capability.
