The Notejoy for Mac app automatically updates Notejoy's theme to reflect your MacOS appearance preference. So if you turn on Dark mode on MacOS, the Notejoy app will automatically update your theme choice to Scarlet Dark.

However, we've now enabled you to subsequently change the Notejoy theme and maintain your preference, regardless of what the MacOS preference is set to. This way you can have Dark mode on in MacOS but still use a non-dark mode theme in Notejoy if you prefer.
