Problème de lancement avec Forge

Bonjour,

Tout d'abord, merci aux bonnes âmes qui m'aideront.
Je suis utilisateur de Minecraft en mode créatif depuis plusieurs années, mais j'ai décidé de me lancer dans Forge et les mod.
Malheureusement, je n'arrive pas à lancer les mod après l'installation de Forge.
J'utilise un mac.

Voici un copier-coller du launcher log :
