In a mammoth effort, Mac User Group volunteers have indexed every issue of the group's monthly magazine from March 1980 to April 2017.
One volunteer has come up with a stand-alone app that uses FileMaker Pro and can theoretically directly open an individual article in the Magazine folder from the index' search feature.
But it's half-baked. Both the app originator & the chief indexers refuse to update past OS X 10.6.8 and their index doesn't work well with the version of FileMaker used (v9) when the end user is running Sierra.
Allegedly, the app wallah is working on updating the app to use a newer FileMaker runtime. Can't come soon enough.
