Pour utiliser Forge-quelle version Minecraft maxi utiliser ?

[Propocraft]

Bonjour,
je reprends le jeu, si je peux, après plus de 18 mois d'arrêt.
Je suis sur MAC et j'ai téléchargé le dernier launcher; puis j'ai démarré le jeu et ça fonctionne en 1.8.8.
Jusque là tout va bien.
---------
Comme j'avais encore une multitude de profil dans le launcher, j'ai effacé tous les vieux.
J'ai téléchargé sur le site d'origine la dernière version Forge en cours: 1.8-11.14.3.1450

Dans les profils, le profil forge apparait bien, j'édite le profil pour demander à utiliser la version release 1.8-Forge11.14.3.1450 (est ce bien la bonne méthode ?) et quand je lance le jeu...Le launcher ne lance pas le jeu, revient à la page de lancement et m'affiche ceci dans la page des logs:

J'ai du merdouiller quelque chose en virant les anciens profils ?
Pourtant quand je joue en 1.8.8, ça roule.

Une idée pour aider un profane en matière d'installation s'il vous plait ?

Veuillez m'excuser, je n'aurais pas du poster ici mais plutôt dans la rubrique, besoin d'aide.
Si un modérateur veut bien déplacer ce fil, pas de souci.
