Launchd 代理未启动

我正在尝试编写一个 launchd 代理，为每个登录 Mac OS X 系统的用户运行一个简单的应用程序。

我创建了一个名为 com.mycompany.myapp.plist 的文件，并将其放置在 /Library/LaunchAgents 中。该文件的内容是：

{
    LimitLoadToSessionType = "Aqua";
    StartInterval = 10;
    OnDemand = NO;
    KeepAlive = YES;
    RunAtLoad = YES;
    Label = "com.mycompany.myapp";
    Program = "/Users/thomi/myapp";
    ProgramArguments = (
        "/Users/thomi/myapp",
        "-l",
        "-d",
    );
}

最初我没有设置 StartInterval 键，因为我认为代理会自动启动。问题是，除非我手动发出以下两个命令，否则代理不会启动：

launchctl load -S Aqua -D all
launchctl start com.mycompany.myapp

此外，当我运行 launchctl list com.mycompany.myapp 时，我会得到以下输出：

{
    "Label" = "com.mycompany.myapp";
    "LimitLoadToSessionType" = "System";
    "OnDemand" = true;
    "LastExitStatus" = 0;
    "TimeOut" = 30;
    "Program" = "/Users/thomi/myapp";
    ProgramArguments = (
        "/Users/thomi/myapp",
        "-l",
        "-d",
    );
};

请注意，LimitLoadToSessionType 参数已更改。

我在这里错过了什么吗？是否有不同的机制来启动这样的代理？为什么 LimitLoadToSessionType 属性发生了变化？

I'm attempting to write a launchd agent that runs a simple application for every user that logs in to the Mac OS X system.

I have created a file named com.mycompany.myapp.plist and placed it in /Library/LaunchAgents. The contents of that file are:

{
    LimitLoadToSessionType = "Aqua";
    StartInterval = 10;
    OnDemand = NO;
    KeepAlive = YES;
    RunAtLoad = YES;
    Label = "com.mycompany.myapp";
    Program = "/Users/thomi/myapp";
    ProgramArguments = (
        "/Users/thomi/myapp",
        "-l",
        "-d",
    );
}

Initially I didn't have the StartInterval key set, since I thought the agent would start automatically. The problem is that the agent does not start unless I manually issue the following two commands:

launchctl load -S Aqua -D all
launchctl start com.mycompany.myapp

Firther, when I run launchctl list com.mycompany.myapp I get the following output:

{
    "Label" = "com.mycompany.myapp";
    "LimitLoadToSessionType" = "System";
    "OnDemand" = true;
    "LastExitStatus" = 0;
    "TimeOut" = 30;
    "Program" = "/Users/thomi/myapp";
    ProgramArguments = (
        "/Users/thomi/myapp",
        "-l",
        "-d",
    );
};

Notice that the LimitLoadToSessionType parameter has changed.

Am I missing something here? Is there a different mechanism to start agents like this? Why has the LimitLoadToSessionType property changed?
