公司部分业务系统依然使用的JDK6，然后便有了下文。

苹果官方JDK6下载地址：https://support.apple.com/kb/dl1572?locale=zh_CN

苹果高版本Mac系统已经不允许直接运行dmg包安装JDK6，以下脚本请用Apple script运行，然后双击桌面的pkg包安装。

set theDMG to choose file with prompt "Please select javaforosx.dmg:" of type {"dmg"}
do shell script "hdiutil mount " & quoted form of POSIX path of theDMG
do shell script "pkgutil --expand /Volumes/Java\\ for\\ macOS\\ 2017-001/JavaForOSX.pkg ~/tmp"
do shell script "hdiutil unmount /Volumes/Java\\ for\\ macOS\\ 2017-001/"
do shell script "sed -i '' 's/return false/return true/g' ~/tmp/Distribution"
do shell script "pkgutil --flatten ~/tmp ~/Desktop/Java.pkg"
do shell script "rm -rf ~/tmp"
display dialog "Modified Java.pkg saved on desktop" buttons {"Ok"}
