创建证书
打开钥匙串应用，菜单栏点击：钥匙串访问 - 证书助理 - 创建证书
一路下一步，直到指定证书位置，选择 系统。
创建完成后，还需要修改权限，钥匙串 - 系统 - 打开刚创建的证书 - 信任 - 始终信任。
# 证书授权，执行命令后输入管理员账号密码
$ codesign -fs {上面创建的证书名称} /usr/local/bin/gdb
# 关闭 MacOS 系统的 SIP 安全验证
$ echo "set startup-with-shell off" >> ~/.gdbinit
$ security find-certificate -c gdb
keychain: "/Library/Keychains/System.keychain"
version: 256
class: 0x80001000
attributes:
...
# 确保证书未过期
$ security find-certificate -p -c gdb | openssl x509 -checkend 0
Certificate will not expire
# 里面应该包括 Code Signing
$ security dump-trust-settings -d
$ codesign --entitlements ~/Downloads/gdb-entitlement.xml -fs gdb $(which gdb)
