各位技术大佬，我碰到个MacBook启动的奇葩问题，折腾好久没头绪，来求支招！

我的MacBook每次重启或关机再开机时，会出现苹果logo和启动音，接着弹出进度条，但通常会卡住1分钟左右就自动重启，这个反复重启的过程要持续30-50分钟，才能成功进入系统。

一旦进到系统里，电脑就完全正常稳定——哪怕玩游戏、连续跑几周不重启都没问题，读写磁盘也毫无异常（磁盘只用了70%左右的空间）。

我已经做了这些排查：

• 用smartctl检查磁盘SMART状态，全正常，重分配扇区计数是100（后面附完整的SMART报告）
• 主电池几乎全新，循环次数不到50次，续航能撑好几个小时
• 不管插电源还是用电池供电，问题都会出现
• 尝试制作了macOS安装U盘，开机按Option键能看到启动选择菜单，但经常直接卡住：要么选不了启动项，要么刚选完就冻住，根本没法引导其他系统
• 电脑完全没有过热的情况

我自己也算懂点软硬件，但这个问题真的把我整懵了，目前怀疑是内存或者主板出问题？有没有什么靠谱的办法能验证这个猜想？

更新2：无法进入诊断模式和恢复模式 #

现在情况更糟了——电脑连诊断模式和恢复模式都进不去，一进去就瞬间卡死，鼠标指针都动不了（屏幕有点灰抱歉，手机拍得太清楚了😂）：

• 诊断模式：诊断模式卡死状态截图
• 恢复模式（试过普通恢复和网络恢复）：两种方式都失败，进入后同样直接卡死：恢复模式卡死状态截图
