tccd 进程是啥子玩意？

[daozhihun]

刚更新到 catalina 的正式版（小白鼠），发现 activity monitor 里面有个叫 tccd 的进程爆占 1.5G 左右的内存？这是个啥玩意？之前版本的系统好像没见过（或者有但是占的内存很少）

搜一下可以找到这个: https://discussions.apple.com/thread/4165543

It looks like it is responsible for managing which applications have access to your contacts. The similarly named tccutil is a command line tool to manage your privacy database. tccd has a database file in each user's home directory ~/Library/Application Support/come.apple.TCC/TCC.db that appears to store which apps you have allowed and denied access to for your contacts.

@Raymon111111 看起来是联系人相关的，可是这占的内存也太离谱了吧，估计是有 bug 吧，一会重启一下看看

@daozhihun 内存占用这么大应该是有 bug, 我看了一下我的就几十 M

刚更新的时候内存 CPU 开销都会很大，因为有很多的后台更新在跑，要等几天稳定后再看

@niubee1 嗯，我一般是刚升级完用个一两天重启一下
