I cant put the Dark mode

Hello, I just saw that scrivener had a dark mode. I tried to put it on my macbook air (High Sierra) but I don’t see the “appearance” tab to put the dark mode. Does anyone have a solution? (sorry about my English, I’m French)

Thanks !

Bonjour.

I believe Dark Mode requires Mojave or later:
