I have developed a software to type IAST/Devanāgarī on a Mac. The software happens to also support Unicode Brāhmī output (currently well supported in Pages) and also limited support for typing Vedic accents (to be expanded in a future version).

I am happy to share the beta with Indology and would appreciate feedbacks in case you try it out.

You can download the latest beta here:

The final version will be ready in <4 weeks.

Kindest Wishes,
