+# Ghostty config — macOS
+
+Ghostty sur macOS a un comportement hybride :
+
+- Le fichier de config principal va dans :
+      ~/Library/Application Support/com.mitchellh.ghostty/config
+- Les thèmes custom, eux, restent lus depuis l'emplacement XDG classique :
+      ~/.config/ghostty/themes/
+
+Comme il n'y a pas (encore) de symlink automatisé, copier à la main :
+
+    mkdir -p ~/.config/ghostty/themes
+    cp .config/ghostty/themes/ultraviolet ~/.config/ghostty/themes/ultraviolet
+
+Puis dans `~/Library/Application Support/com.mitchellh.ghostty/config`, ajouter :
+
+    theme = ultraviolet
