Oui : c'est ça -->
- confirme si tu veux que je te passe les commandes de recopie et de reconstruction des caches de démarrage-Système.
L'efficacité du SSD risque de diminuer marginalement si tu n'actives pas le TRIM (effacement des cellules vacantes) > mais tout dépend aussi de l'usage que tu fais de ce Mac -->

=> à toi de dire ce que tu décides. Si tu veux qu'on tente de l'activer via la recopie de l'extension facultative > préviens ici lorsque ta sauvegarde TM aura été mise-à-jour.
sudo cp -av /System/Library/Filesystems/AppleDataSetManagement.kext /System/Library/Extensions
sudo touch /System/Library/Extensions
sudo kextcache -system-cache
sudo kextcache -system-prelinked-kernel
Alors passe les commandes (séparément) :
Bloc de code:sudo cp -av /System/Library/Filesystems/AppleDataSetManagement.kext /System/Library/Extensions sudo touch /System/Library/Extensions sudo kextcache -system-cache sudo kextcache -system-prelinked-kernel
- la 1ère copie l'extension facultative AppleDataSetManagement.kext => dans le dossier des Extensions du Système
- la 2è actualise la date du dernier accès au dossier des Extensions > afin de forcer la remise en cache de ce dossier
- la 3è reconstruit les caches d'informations relatifs aux extensions
=> poste les retours que tu aurais obtenus.
- la 4è met à jour le cache prelinkedkernel > qui sert de cache de démarrage du volume (chargé par le lanceur boof.efi au démarrage)

Bon ! le redémarrage est sans problème (il faut toujours se méfier quand on affecte le dossier des Extensions du Système).
Tu n'as aucune commande à passer > puisque l'extension qui gère le TRIM > présente dans le dossier des Extensions du Système => a sans doute été injectée dans le kernel au démarrage par le lanceur boot.efi.
- va à : Menu > À propos de ce Mac > Rapport Système > Matériel > SATA/SATA Express => dans le champ droit d'informations > sélectionne ton SSD et voit si à : "Prise en charge du TRIM" tu as la mention : "Oui" en face.
Note : je fais une pause. Je reviendrai aux nouvelles plus tard.
Non, il n'y aura pas de problème. Pourquoi ? Par défaut, dans tout SSD de n'importe quelle marque, il y a d'intégré un micro logiciel ayant pour nom Garbage Collector (ramasse-miettes) qui est son équivalent. La contrepartie de ne pas activer dès le départ l'option Trim est que pour que le micro logiciel fasse son travail, qu'il sera nécessaire de ne pas éteindre son Mac toute une nuit, donc le laisser en veille.Sinon, conseille-tu de le faire ou le TRIM désactivé c'est pas grave ? Il me semble que ça diminue l'efficacité et fiabilité du SSD si on l'active pas, non ?
sudo trimforce enable
@ Locke
GTV a un OS High Sierra patché sur un MacBook Pro 2009 => la commande ne passe pas.
@ GTV
Alors tant pis pour le TRIM...
Ah oui, j'avais complètement oublié, sinon il restera la solution que je mentionne en réponse #53.GTV a un OS High Sierra patché sur un MacBook Pro 2009 => la commande ne passe pas.
