The 1.0.1 version of fmXRayTables for Mac was available as a free download on our website. The actual developer of this free software for Mac is Workflow Data Systems, LLC.
From the developer:
fmXRayTables is a tool for FileMaker Pro Advanced that provides fast access to the properties of FileMaker Fields and Tables. Because fmXRayTables requires the ability to copy field and table definitions, it requires FileMaker Pro Advanced. fmXRayTables appears to generally work with earlier FileMaker versions, but has not been substantively tested with them.
