Panique du noyau Mac mini WindowServer plusieurs fois par jour avec «un élément de zone libéré a été modifié»

J'ai eu des problèmes avec mon Mac mini. Il se bloque au hasard plusieurs fois par jour. Parfois, cela semble être déclenché par n'importe quel navigateur, mais Chrome est le pire. YouTube semble être le plus grand coupable. J'ai complètement effacé le lecteur et réinstallé le système d'exploitation, mais cela n'a pas résolu le problème. Voici mon rapport d'accident. Quelqu'un peut-il m'aider à comprendre cela?
