MacOS 查看 ssh 登录信息

cp /System/Library/LaunchDaemons/ssh.plist /Library/LaunchDaemons/ssh.plist

sudo vim /Library/LaunchDaemons/ssh.plist

在里面加上下面代码后面两句

 <array>
                    <string>/usr/sbin/sshd</string>
                    <string>-i</string>
                    <string>-E</string>
                    <string>/var/log/system.log</string> 
 </array>

然后重新启动

launchctl unload /System/Library/LaunchDaemons/ssh.plist && launchctl load -w /Library/LaunchDaemons/ssh.plist

查看登录信息

cat /var/log/system.log | grep sshd
