貌似刚拿到电脑是自己手动编译安装了vim 7.3,后来都是brew install vim最新版本。

今天vim出了点问题,发现系统上还有个vim 7.3,准备删除时就报Operation not permitted

问题描述

$ sudo rm -rf /usr/share/vim/
rm: /usr/share/vim: Operation not permitted

习惯Linux我就觉得有没有搞错,我是root呀,什么文件不能删除呢。。。

Google下才知道Apple为了防止恶意软件破坏系统开启了System Intregrity Protection

解决

查看文件flag:

$ ls -lO /usr/share/vim
-rwxr-xr-x  8 root  wheel  restricted - Aug  2 22:36 /usr/share/vim

  • reboot
  • as soon as you hear the “Mac sound” on the grey screen, press Cmd+R to enter Recovery mode
  • Open Utilities->Terminal
  • Run the command csrutil disable
  • Reboot, you’ll land in the normal OS with SIP disabled
  • do all the changes you’d like to do
  • Reboot again
  • as soon as you hear the “Mac sound” on the grey screen, press Cmd+R to enter Recovery mode
  • Enable SIP with csrutil enable
  • Reboot again
  • done

流程如下:

重启 -> Command+R,进入恢复模式 -> 在终端通过csrutil disable禁掉SIP -> 重启 -> 删除文件 -> 再通过Command+R,进入恢复模式 -> 通过 csrutil enable 启用SIP -> 再次重启

查看SIP状态:

$ csrutil status
System Integrity Protection status: enabled.
