苹果证实 MacBook Pro 热保护问题，已释出固件修复
苹果最近发布的配备英特尔 6 核 Core i9 处理器的新款 MacBook Pro 笔记本电脑被发现存在热保护限制性能的问题，而苹果现在已经证实了该问题，它向消费者表示歉意并释出了新更新修复该问题。问题看起来与英特尔有点关系。CPU 由 Voltage Regulator Module（VRM）供电，当 CPU 准备满负荷运转，它要求 VRM 提供 125W 的电，这导致了 VRM 变热接近其最大热限制值，于是 VRM 向主板发出信号限制 CPU 的性能降低功耗让 VRM 降温。问题部分归咎于英特尔文档中有关最大热功耗值出错。Media
