Rogue Amoebahas “retired” its Nicecast app for the Mac. It’s no longer available for purchase, and no further updates are planned. The software allowed you to broadcast music from macOS with an Internet audio broadcaster and server wrapped into one.
Here’s what the folks at Rogue Amoeba have to say about the situation:
Starting in 2003, Nicecast allowed hobbyists to live out their DJ fantasies, while terrestrial radio stations could provide online access to their content. However, the app never gained widespread popularity, always remaining a junior player in our product lineup. As internet radio has fizzled, and Apple has planned breaking changes to MacOS, we must now put Nicecast out to pasture.
It's tough to retire an application, particularly one that's been developed for almost fifteen years. However, our customers are best served when our limited resources are optimized. We're sad to see Nicecast go, but excited to dedicate our energies to more modern projects which will help even more users.
The last planned version of Nicecast, version 1.11.13, is available for existing users from Rogue Amoeba's Legacy page. Nicecast will be supported on macOS 10.10 through 10.13 until the end of 2018, after which it will be fully deprecated.
