¿Cómo puedo ocultar los iconos del escritorio en Mojave?

Mojave admite la ocultación de elementos del escritorio. Si por alguna razón true o false no funcionan, intente usar 1 o 0. El siguiente ejemplo funcionó en macOS 10.14.5 y oculta elementos de la vista:

$ defaults write com.apple.finder CreateDesktop 0; killall Finder

• Pude usar 0 o false y hacerlo funcionar en 10.14.5, por lo que si no funcionó en una versión anterior de Mojave, tal vez fue un error que ya se ha solucionado.
• Buen punto, @TJLuoma: edité mi respuesta para que se adapte a ambas formas de establecer valores booleanos.
• funcionó para mí. mojave 14.5

No existe un comando nativo en macOS para ocultar solo los iconos del escritorio, sin embargo, puede utilizar una aplicación de terceros como HiddenMe para lograr esto.

Hice una clase simple en Swift que simplemente busca notificaciones para ocultar o mostrar los iconos del escritorio. parece hacer lo mismo que HiddenMe. Funciona incluso en una aplicación de espacio aislado.

si hay varios monitores físicos con el mismo tamaño, la clase puede confundirse sobre qué escritorio va con qué monitor. Puede solucionar esto obteniendo CGRect para cada Escritorio y mirando CGRect para cada pantalla. Aparentemente, hay una función auxiliar que hará esto, pero es beta y solo está disponible en ObjC.

Encontré La forma más fácil y limpia de ocultar los elementos del escritorio mediante programación o mediante la línea de comandos es colocando un punto delante del nombre del archivo, para que no existan archivos ocultos. De esta forma, puede ocultar todos los elementos del escritorio o uno solo.
