    然后在命令行中执行如下命令即可

liumiaocn:gdb liumiao$ sudo killall taskgated
    Password:
    liumiaocn:gdb liumiao$ codesign -fs gdb_codesign /usr/local/bin/gdb
    liumiaocn:gdb liumiao$

注意第2条命令执行时需要输入相应的用户名和密码, 然后重启系统

    目前本文使用的Catalina的缺省terminal目前存在这个问题，伤未发现太好的办法，建议直接换成iterm2进行使用：[https://www.iterm2.com/][https_www.iterm2.com]

## 其他问题 ##

安装时已经提示，Sierra之后由于系统集成性保护SIP的缘故，需要在.gdbinit或者每次执行之前设定startup-with-shell 未off

On 10.12 (Sierra) or later with SIP, you need to run this:
      echo "set startup-with-shell off" >> ~/.gdbinit
