launchctl 命令加载，卸载开机自动运行的服务，在 OS X 中，服务本身存储在 .plist 文件中（即 property list），这些文件的位置一般在 ~/Library/LaunchAgents 或 /Library/LaunchAgents。可以使用 launchctl load $PATH_TO_LIST 和 unload them with launchctl unload $PATH_TO_LIST 命令来加载/卸载他们。加载就是允许这个程序开机执行，卸载反之。

如果你使用 Homebrew 安装过 mysql 那么下面的安装后提示你可能比较熟悉

To have launchd start mysql at login:
   ln -sfv /usr/local/opt/mysql/*.plist ~/Library/LaunchAgents
Then to load mysql now:

Install HomeBrew first

brew update
brew tap caskroom/cask
brew install brew-cask

If you get the error "already installed", follow the instructions to unlink it, then install again:
