Storage system check exit code is 0

Bon ce que je sais est que le code 0 signifie : pas d'erreur.
Sinon je passe la main aux experts du terminal pour des explications plus détaillées

C’est bien pour moi si ce n’est un élevage de snapshots qui doivent te bouffer une bonne partie de ton volume de stockage. Peut-être est ce la sur allocation évoquée en avertissement final.
Tu peux passer la commande suivante depuis le terminal pour les supprimer

sudo tmutil thinlocalsnapshots / 99000000000 4 ; say 'ENFIN TERMINÉ LA PURGE’
