macOS 10.14 mojave安装低版本iTunes 12.6.x

iTunes 12.6.x能管理部署app(下载.ipa包），后续的iTunes已经删除这项功能。苹果在最新系统10.14上再也不支持安装12.6版本的iTunes。安装会提示“您的系统不支持本软件”

下面是解决方案：

首先，下载iTunes 12.6版本（最新版本12.6.5）：
support.apple.com/zh-cn/HT208…

利用脚本编辑器运行脚本安装低版本iTunes：

一、关闭SIP系统完整性保护（不关会致使无操做权限）

参考百度经验教程：jingyan.baidu.com/article/9c6…

二、打开脚本编辑器，将如下代码复制到脚本编辑器运行（卸载iTunes并重装）

set question to display dialog "Delete iTtunes?" buttons {"Yes", "No"} default button 1
set answer to button returned of question
if answer is equal to "Yes" then
    do shell script "rm -rf /Applications/iTunes.app" with administrator privileges
    display dialog "iTunes was deleted" buttons {"Ok"}
    set theDMG to choose file with prompt "Please select iTunes 12.6 dmg file:" of type {"dmg"}
    do shell script "hdiutil mount " & quoted form of POSIX path of theDMG
    do shell script "pkgutil --expand /Volumes/iTunes/Install\\ iTunes.pkg ~/tmp"
    do shell script "sed -i '' 's/18A1/14F2511/g' ~/tmp/Distribution"
    do shell script "sed -i '' 's/gt/lt/g' ~/tmp/Distribution"
    do shell script "pkgutil --flatten ~/tmp ~/Desktop/iTunes.pkg"
    do shell script "hdiutil unmount /Volumes/iTunes/"
    do shell script "rm -rf ~/tmp"
end if
if answer is equal to "No" then
    display dialog "iTunes was not deleted" buttons {"Ok"}
    return
end if

set question to display dialog "Install iTtunes?" buttons {"Yes", "No"} default button 1
set answer to button returned of question
if answer is equal to "Yes" then
    do shell script "open ~/Desktop/iTunes.pkg"
    return
end if
if answer is equal to "No" then
    display dialog "Modified iTunes.pkg saved on desktop" buttons {"Ok"}
    return
end if复制代码

运行时若是 提示 iTunes Library.itl 错误,删掉就ok

终端运行命令：sudo rm ~/Music/iTunes/iTunes\ Library.itl

三、运行如下代码（不卸载直接覆盖安装）

display dialog "Please select iTunes 12.6 dmg file" buttons {"Ok"}
set theDMG to choose file with prompt "Please select iTunes 12.6 dmg file:" of type {"dmg"}
do shell script "hdiutil mount " & quoted form of POSIX path of theDMG
do shell script "pkgutil --expand /Volumes/iTunes/Install\\ iTunes.pkg ~/tmp"
do shell script "sed -i '' 's/18A1/14F2511/g' ~/tmp/Distribution"
do shell script "sed -i '' 's/gt/lt/g' ~/tmp/Distribution"
do shell script "pkgutil --flatten ~/tmp ~/Desktop/iTunes.pkg"
do shell script "hdiutil unmount /Volumes/iTunes/"
do shell script "rm -rf ~/tmp"

set question to display dialog "Install iTtunes?" buttons {"Yes", "No"} default button 1
set answer to button returned of question
if answer is equal to "Yes" then
    do shell script "open ~/Desktop/iTunes.pkg"
    return
end if
if answer is equal to "No" then
    display dialog "Modified iTunes.pkg saved on desktop" buttons {"Ok"}
    return
end if复制代码

运行脚本卸载iTunes后，按照脚本提示选择12.6版本iTunes的安装包进行安装。

四、从新开启SIP

安装完成而且iTunes能正常使用后建议开启SIP，增长安全性仍是颇有必要的。固然你也能够选择无视SIP，随你高兴😄
