解决办法:
首先我们把MYSQL卸载了(系统偏好设置-->点击底部MYSQL-->点击unInstall)
然后需要通过命令彻底删除mysql相关文件
命令如下:
sudo rm /usr/local/mysqlsudo rm -rf /usr/local/mysql*sudo rm -rf /Library/StartupItems/MySQLCOMsudo rm -rf /Library/PreferencePanes/My*sudo rm -rf /Library/Receipts/mysql*sudo rm -rf /Library/Receipts/MySQL*sudo rm -rf /var/db/receipts/com.mysql.*
3.然后需要重启电脑
重新安装Mysql
然后打开Navicat就可以连接成功了
