If you go to the end with purple end fire enabled on macOS, it will just crash your game (specifically Java itself and not Minecraft like when you try to enable something else that isn't supported on macOS) so it should be marked as does not work on macOS within the config menu

That is very odd... That feature doesn't use code that should break on Mac interesting

ya I assumed that was the case, based on the fact that it wasn't marked that it would not work on macOS. This is a recording of what happens when I try to enable it in the end.

and this is the log https://mclo.gs/dYcIlpd
