Mac使用技巧若干-持續更新

打開安全設置中的允許“任何來源”選項

macOS Sierra(10.12) 默認關閉了安全性與隱私設置中的允許“任何來源”選項，這給安裝第三方應用帶來了不便，使用以下命令設置，重新打開：

sudo spctl --master-disable

徹底刪除Mysql

sudo rm /usr/local/mysql
sudo rm -rf /usr/local/mysql*
sudo rm -rf /Library/StartupItems/MySQLCOM
sudo rm -rf /Library/PreferencePanes/My*
vim /etc/hostconfig and removed the line MYSQLCOM=-YES-
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.*
