On macOS, fast forward does not run as fast as the CPU can do. It runs about twice the normal speed. This happens at least on El Capitan.

Following information unrelated to OpenTTD, specifically I'm not implying that I've run OpenTTD inside DOSBox -- <>:
I've had the same issue with DOSBox, and I found that it behaved like this when DOSBox was compiled on a contemporary macOS machine (I think Yosemite or later), but when I compiled it on Snow Leopard, the frame refresh restriction went away, even when running on El Capitan. I have not found out what caused this. Maybe someone can enlighten me.
This task depends upon
