Here is a mac native app, that works exceptionally and has -the- best support I've ever experienced. Had a frustrating bug and within hours, the developer had found the issue and sent me a custom version that resolved it until a new version could be published.
It's exceptional and light years ahead of its competitors. If you need an index on a Mac, this is the option. Your time is more valuable than the cost of this software. It saved me dozens of hours.

Developing a working index that maps into your document and provides clear useful information is a breeze with this software. The learning curve to understand and use the software is not impossible at all. A good index requires you to know your book, but also to have the software that can do it. If a publisher produces your manuscript in a pdf - save yourself the headache - this software will save you time, money and produce great results.
