Question

我正试图通过Apple Remote Desktop设置一个偏好，以便在130个Mac上以32位模式打开Firefox。最简单的方法是使用defaults write，遗憾的是我没有找到任何关于此的文档，我无法弄清楚编写不在根级别的字符串的语法。

该文件为~/Library/Preferences/com.apple.LaunchServices.plist

我需要将字符串x86_64更改为i386

<dict>
<key>LSArchitecturesForX86_64v2</key>
<dict>      
    <key>org.mozilla.firefox</key>
    <array>
        <data>

我不认为有一种方法可以使用默认值（嗯，有，但它涉及转储整个LSArchitecturesForX86_64v2字典，编辑它，然后重新导入）。但PlistBuddy可以胜任这项工作：

/usr/libexec/PlistBuddy -c "set :LSArchitecturesForX86_64v2:org.mozilla.firefox:1 i386" ~/Library/Preferences/com.apple.LaunchServices.plist

在向130台计算机部署任何东西之前的常见警告：先测试一下（我试过一次......），然后让它备份每台计算机上的相关文件，这样如果有什么东西横向移动就可以回滚
