我正在尝试通过 Apple 远程桌面设置 Firefox 在 130 台 Mac 上以 32 位模式打开的首选项。最简单的方法通常是defaults write不幸的是我还没有找到任何关于此的文档，而且我无法弄清楚编写不在根级别的字符串的语法。

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

我需要将字符串更改x86_64为i386

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

我认为没有办法使用默认值（嗯，有，但它涉及转储整个 LSArchitecturesForX86_64v2 字典，编辑它，然后重新导入）。但是 PlistBuddy 可以完成这项工作：

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

在将任何东西部署到 130 台计算机之前，通常需要注意的是：首先对此进行测试（我尝试过一次……），然后将其备份到每台计算机上的相关文件，这样如果确实出现问题，您可以将其回滚。
