我在 Mac Mini 上运行的是 OS X 10.6.8。今天我尝试安装 3 个应用程序，但全部安装失败。我想知道这些失败是否有共同之处。
首先，我安装了 GraphViz。安装成功，但当我尝试打开任何 .dot 文件时，出现一个对话框，提示“GraphViz 已意外退出”。
接下来我安装了 Doxygen。它已安装，但当我尝试启动它时，出现一个对话框，提示我 Doxywizard 意外退出。
经过一番谷歌搜索，我认为我的系统可能缺少 QT，这就是问题所在。我下载了 Qt 4.8.4 软件包并进行了安装。但是当我尝试启动 qtdemo.app 或 qt 安装附带的任何其他应用程序时，我收到一个对话框，提示我无法打开该应用程序，因为这种类型的 Mac 不支持该应用程序。
我有来自 GraphViz 和 Doxygen 的崩溃日志。它们很长，我认为没有必要发布它们，除非它们能帮助别人确定我的问题。
谢谢
