I now know that the KAuth helper (DBus service executable, ksysguardprocesslist_helper in this case) has to connect on the system dbus. That removes the need for a hack, basically all I have to do is set <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">DBUS_LAUNCHD_SESSION_BUS_SOCKET</code> to the system dbus socket in the root user's environment.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">It also means the libdbus patch can actually be discussed for upstreaming; the reason this particular feature doesn't work on OS X seems to be that helpers (services) like ksysguardprocesslist_helper don't even attempt to connect on the system bus on OS X. They just bail out when they fail to read the session bus socket name.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">If we really wanted to tackle this problem correctly we'd write a specific (native) helper backend for KAuth, probably based on Apple's Service Management framework (which leverages launchd). I doubt that's worth the trouble at this point.</p></pre>

In the meantime I'm leaving the libksysguard features disabled that require elevated privileges.</p></pre>

That feature is justified as it is used by KDevelop in order to obtain the list of processes one can attach a debugger to.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Mac OS X is tricky because it requires special privileges in order to obtain certain types of information for any running process. For example, even obtaining the number of threads spawned by a foreign process requires privileges that aren't trivial to set up. I've prepared the terrain, but also implemented a fallback strategy that calls <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">ps</code> to be sure that crucial information like the command name is available for all processes.</p></pre>
