我也来吐槽了, MacOS 10.15.2 开机卡到生活无法自理

开机的时候(休眠的时候)占用大概是这么多,然后开机之后,CPU 就血崩,因为一个叫secd的程序占了 88%的 CPU 资源。似乎是检查安全性导致的,并且现在新开一个 terminal tab 都卡 5 ~ 10 秒,难道和 iOS 一样开始让大家换电脑了?=A=
The "d" stands for "daemon", which basically means a helper process that always runs in the background. The sec very likely stands for "security". So secd is the "security daemon". Which makes sense because you said it looks like it works with keychain stuff.
