MAC 系统频繁崩溃 求解

奔溃后自动重启 提示向苹果报告的报告内容 有没有大神能看懂是什么原因!

MBP16 寸遇到过和你类似的问题，但报告内容不一样。我后来找到了 100%重现的规律：eGPU 休眠然后唤醒，继续播放 Safari 中的 youtube 视频：

你这排版看得眼睛要瞎…应该是 iokit.IOAcceleratorFamily2 的 page fault，你具体可以参考这个帖子 trace back： https://objective-see.com/blog/blog_0x27.html

[mccken]

我 mac qq 也是总崩溃，2019 款 pro

[NSChris]

我也经常崩溃，我发现是我插上的外置显卡的原因
插上显卡内存使用太多就容易崩溃
以前都没有这个问题，可能是升级系统之后不兼容了 ，现在都不知道咋搞

[fansangg]

升了 10.15.5，平均一天崩一次，经常开盖出现灰屏，下方一个进度条

[beny2mor]

@fansangg 之前没出现过这个情况，升了 10.15.5 就这样了...

[alei814]

10.15.5 。。。受害者加我一个，MacBook Pro (13-inch, 2017, Four Thunderbolt 3 Ports)更新完系统重启好多遍了。。。准备去天才吧看看了
