    <p>I think you could possibly make use of the built in facilities Launchd and CrashReporter to achieve your requirements.</p> <p><a href="https://developer.apple.com/library/mac/#documentation/Darwin/Reference/ManPages/man8/launchd.8.html#//apple_ref/doc/man/8/launchd" rel="nofollow">Launchd</a> is the OS X system supervisor intended for launching and monitoring background processes, and would be typically used to run XPC services. Launchd agents can react to various system events, and can be configured to restart processes in the event of them crashing ( specified via the <code>KeepAlive/SuccessfulExit</code> key in the <a href="https://developer.apple.com/library/mac/#documentation/Darwin/Reference/ManPages/man5/launchd.plist.5.html" rel="nofollow">property list</a>)</p> <p>Launchd can be set to react to various system events as launch event, including monitoring files and directories, scheduled times, or listening to network connections.</p> <p><a href="https://developer.apple.com/library/mac/#technotes/tn2004/tn2123.html" rel="nofollow">CrashReporter</a> is the OS X system facility that catches and logs all process crashes. It logs through the <a href="https://developer.apple.com/library/mac/#documentation/MacOSX/Conceptual/BPSystemStartup/Chapters/LoggingErrorsAndWarnings.html#//apple_ref/doc/uid/10000172i-SW8-SW1" rel="nofollow">AppleSystemLogger facility</a> and can be accessed with the syslog tools as documented in the linked TechNote. On Mountain Lion, user process crash reports end up in <code>~/Library/DiagnosticReports/</code> , with a crashlog and plist file pair created per crash event.</p> <p>I think you could use these features in a couple of ways to achieve your requirement, if launchd is responsible for running the xpc services, it can take reponsibility for restarting them on crash events, and they can be dissociated from any app crashes. </p> <p>You could write a launchd agent that responds to for crash events by montioring the crash report directory (e.g. using the <code>QueueDirectories</code> property) for new logs and re-launches your applicaton, or presents notifications. </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
