Mac 异常死机,多次发生.

[hay313955795]

先说一下设备情况:17 款的 macbook pro.

描述一下情况.

电脑插电使用,经常用着用着就死机,鼠标不能动,再隔一段时间就会自动重启,然后再次使用隔一段时间又会重复之前的死机.

个人猜测:

之前以为是公司的电流不稳才会导致这个问题,后来有一天在家里插电用的时候也会发生这个情况.

然后观察了几次发现,当笔记本电池电量不足的时候电脑会有一定几率的情况死机.如果插上电源让电脑电量充到一定程度,大概率就不会发生死机的情况

不知道还有没有 xd 遇到和我一样的情况.印象里再发生这个情况之前也没有进行系统升级的操作.

想问下这个情况要怎么解决???有时间写代码的时候突然死机,就很恼火.

刚刚又异常了.....有一个奔溃的日志,但是我看不懂有懂的老哥帮我看看吗

刚刚下午升级了一下系统版本.好像电脑又奇迹般的活过来了.重复早上那些动作,也没有再次死机,难道真的是系统问题导致的?

mac 有个系统日志，如果你是程序员，应该很容易看懂。

曾经通过看 mac 日志解决了好几个问题：使用中无故重启，timemachine 不能备份，开盖后总是会自动重启

@yuanmomo 也看过,但是看不太懂..

同样有这个问题，我是 20 款 pro ，从之前 Big Sur 的时候就出现了时不时登出的情况。最近每天中午看网课直播都会固定登出一次。
刚才又重启了，我立刻看了一下 system.log ，登出前后日志如下：
```

```
但是 logoutd 前后的日志和重启这件事情似乎并无关联，不知道怎么继续排查。

有段时间经常提示 电脑从异常关机中恢复 后来好了 现在用的 veture 完美, 18 款 Intel

[xinqianbobo]

我也遇到过，但是也遇到过不是卡着不动，而是鼠标指针只能在当前屏下移动并且鼠标指针处于左键单击状态，然后触控板其他手势失效，无法切屏，无法打开任何软件。 长时间无反应所以强制关机，关机关，风扇狂转 10-15 秒后，紫屏后重启。
