La gestion des param\u00e8tres syst\u00e8me \u00e0 grande \u00e9chelle est une responsabilit\u00e9 essentielle pour les professionnels de l’informatique et les fournisseurs de services g\u00e9r\u00e9s (MSP)<\/a>. macOS, bien que convivial en apparence, peut poser des probl\u00e8mes de configuration lorsqu’il s’agit d’appliquer des param\u00e8tres uniformes \u00e0 plusieurs utilisateurs ou syst\u00e8mes. L’un de ces param\u00e8tres est la visibilit\u00e9 des extensions de fichiers, qui peut \u00eatre essentielle pour les diagnostics informatiques, l’int\u00e9grit\u00e9 des types de fichiers et la formation des utilisateurs. Cet article explique comment activer ou d\u00e9sactiver les extensions de fichiers sur macOS avec un script Shell<\/strong> pour tous les utilisateurs via l’automatisation de la ligne de commande.<\/p>\n

Contexte<\/h2>\n

Les extensions de fichiers sont essentielles pour distinguer les types de fichiers, en particulier lorsque les ic\u00f4nes des fichiers ou les applications par d\u00e9faut sont ambigu\u00ebs. Bien que les utilisateurs puissent basculer ce param\u00e8tre manuellement via les pr\u00e9f\u00e9rences du Finder, les environnements d’entreprise exigent l’automatisation, en particulier lorsqu’il s’agit de g\u00e9rer des centaines de machines. Les MSP et les administrateurs syst\u00e8me ont souvent besoin de renforcer la visibilit\u00e9 pour \u00e9viter les erreurs des utilisateurs, permettre une gestion efficace des fichiers ou se conformer aux directives de la politique. Le script pr\u00e9sent\u00e9 ici permet d’activer ou de d\u00e9sactiver la fonction \u00ab\u00a0Afficher toutes les extensions de fichiers\u00a0\u00bb pour tous les comptes d’utilisateurs, de mani\u00e8re automatique, fiable et avec une intervention minimale.<\/p>\n

Cet outil est particuli\u00e8rement pr\u00e9cieux lorsqu’il est associ\u00e9 \u00e0 des solutions de gestion \u00e0 distance telles que NinjaOne, o\u00f9 l’automatisation<\/a> peut r\u00e9duire le temps de r\u00e9solution, renforcer les postures de s\u00e9curit\u00e9 et \u00e9liminer les incoh\u00e9rences entre les d\u00e9ploiements.<\/p>\n
