Comment puis-je masquer les icônes du bureau sur Mojave?

Mojave prend en charge le masquage des éléments du bureau. Si pour une raison quelconque true ou false ne fonctionne pas, essayez dutiliser 1 ou 0. Lexemple ci-dessous a travaillé sur macOS 10.14.5 et masque les éléments de la vue:

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

• Jai pu utiliser 0 ou false et le faire fonctionner sur 10.14.5, donc sil ne fonctionnait pas dans une version antérieure de Mojave, cétait peut-être un bogue qui a depuis été corrigé.
• Bon point, @TJLuoma – Jai modifié ma réponse pour quelle prenne en compte les deux façons de définir des valeurs booléennes.
• a fonctionné pour moi. mojave 14.5

Il ny a pas de commande native dans macOS pour masquer uniquement les icônes du bureau, cependant, vous peut utiliser une application tierce telle que HiddenMe pour ce faire.

Jai créé une classe simple dans Swift qui regarde simplement les notifications pour masquer ou afficher les icônes du bureau. il semble faire la même chose que HiddenMe. Cela fonctionne même dans une application en bac à sable.

sil y a plusieurs moniteurs physiques avec la même taille, la classe peut être confuse sur quel bureau va avec quel moniteur. Vous pouvez contourner ce problème en obtenant CGRect pour chaque bureau et en regardant CGRect pour chaque écran. Apparemment, il existe une fonction dassistance qui fera cela, mais cest une version bêta et uniquement disponible dans ObjC.

Jai trouvé le moyen le plus simple et le plus propre de masquer les éléments du bureau par programmation ou via la ligne de commande est de placer un point devant le nom du fichier, ce qui en fait des fichiers cachés. De cette façon, vous pouvez masquer tout ou un élément individuel sur le bureau.
