Pourquoi je ne peux pas supprimer iTunes et comment le faire ?

Si vous souhaitez simplement l'empêcher de se lancer, exécutez la commande

sudo chmod 000 /Applications/iTunes.app

devrait faire l'affaire. Cette opération doit être répétée après chaque mise à jour d'OS X/iTunes, mais elle s'applique également à toute solution impliquant la suppression d'applications standard.

PS : Juste pour mettre les choses en perspective en ce qui concerne l'espace disque :

root@Mithos:/Applications$ du -sm iTunes.app Chess.app Game\ Center.app Stickies.app Photo\ Booth.app Photos.app 
191 iTunes.app
5   Chess.app
3   Game Center.app
5   Stickies.app
5   Photo Booth.app
31  Photos.app

Même sur un système doté d'un disque SSD de 128 Go, l'extraction de 200 Mo ne donne pas grand-chose.

La désinstallation d'iTunes n'est pas prise en charge par Apple. En le glissant dans la corbeille et en essayant de le supprimer, vous obtiendrez le message suivant : "iTunes ne peut pas être modifié ou supprimé car il est requis par OS X".

Même si vous le faites manuellement, il reviendra avec les mises à jour du système d'exploitation ; et vous risquez de casser certaines choses comme certaines associations de fichiers et les capacités de connexion/synchronisation de l'iPhone.

La meilleure solution est probablement de laisser le problème en suspens et de l'ignorer.

rm -f -r /Applications/iTunes.app

l'a supprimé pour moi, tout comme Chess, Game Centre, Photo Booth et Stickies.

Vous devez d'abord décharger l'application ituneshelper (utilisez le moniteur d'activité). Je n'ai pas eu besoin de le faire car je supprime les déchets inutiles d'OS X immédiatement après le lancement.

Il est faux de dire qu'il est requis par OS X, il est seulement requis par Apple pour vous vendre des produits.

voici un Application AppleScript pour l'automatiser, ou vous pouvez simplement coller ce qui suit dans l'éditeur AppleScript et l'adapter à votre goût :
