让 Mac 退出屏幕保护/睡眠后立即要求密码
将 askForPassword 设为 1、askForPasswordDelay 设为 0，锁屏后不再有免密宽限期。
运行 defaults write com.apple.screensaver askForPassword -int 1 && defaults write com.apple.screensaver askForPasswordDelay -int 0。
01命令
命令
$ defaults write com.apple.screensaver askForPassword -int 1 && defaults write com.apple.screensaver askForPasswordDelay -int 002作用说明
askForPassword 决定屏幕保护结束或显示器睡眠后是否需要密码，askForPasswordDelay 则是免输入密码的宽限秒数。把延迟设为 0，同事就不能趁你离开的几十秒唤醒 Mac 查看邮件。新版系统里对应的选项在系统设置 > 锁定屏幕中；这些 defaults 键对当前用户仍然有效，也很适合写进自动化配置脚本。
03风险
!注意: 延迟为 0 后，短暂黑屏回来都要输密码，独占使用的台式机可能会觉得麻烦。

- macOS defaults - read, write and delete macOS user defaults依据: Documents `defaults write domain key -int value` for integer preference keys in per-app domains such as com.apple.screensaver, and `defaults delete` to remove overrides.
- macOS setup dotfiles (.macos)依据: Contains 'defaults write com.apple.screensaver askForPassword -int 1' and 'defaults write com.apple.screensaver askForPasswordDelay -int 0' with comments about requiring a password immediately after sleep or screensaver.
