My bad. I misread the official website:

> We don't currently support Apple Silicon, as there is not yet a Kokoro implementation in MLX. As soon as it will be available, we will support it.

I thought that meant that it didn't support Apple Silicon in general, but they were just talking about GPU support.

though they wouldn't need to use MLX, could also use pytorch etc

I think there's an issue somewhere in Kokoro though which means it doesn't actually take advantage of MPS, I did get a modified version up and running, but it was no faster than CPU, even though it passed all the internal tests using mps.

I might try using F5-TTS-MLX instead actually (https://github.com/lucasnewman/f5-tts-mlx) and see how that does.
