Merci pour ce petit tuto bien sympa. simplement (et je ne voudrais pas dire de bêtises) je crois que le trim sous mac os 11 (big sur) n’est plus possible

au sens ou s’il est activé il pose de Gros problemes au systeme.

Bonjour jeff,

J’ai fait ce tutoriel, il y a quelques années ou les SSD étaient installés avec une partition Mac extended. Depuis, il y a APFS qui est sortie et Trim est devenu obsolète, car APFS gère mieux les fichiers que Trim.

Donc, ça n’a rien à voir avec Big Sur, mais je vais tout de même rajouter une mention au tutoriel.

Je ne peux lui donner 30, il y a faute de français. Trim n’est pas activer, mais bien activé
