mac os 10.15安裝jdk 1.6

1、如果出現報錯 已經安裝了最高版本

請看下面方法處理錯誤

1、在mac的訪達中 找到 “腳本編輯器”
輸入如下(原文：https://forums.macrumors.com/threads/java-6-runtime-legacy-version-for-macos-catalina.2195954/)

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"}

2、運行腳本，然后選擇剛才下載的JavaForOSX.dmg，然后成功以后 會在桌面有一個java.dmg 運行就ok了
