Re: NSTerminateLater and thread
I will try that, anyway I think the OS should grant the developer to manage the logout at his wish. For example, I return NSTerminateLater, then I launch my task in a thread and, at then end of the task I call replyToApplicationShouldTerminate:YES Easy. I understand the developer could even "forget" to call replyToApplicationShouldTerminate but there are so many other bad and worse things he can do actually, so why don't give him the freedom to make this mistake too? Mistery.

Repeatedly call runModalSession until the task is finished or the user cancelled. This worked fine for me in a similar situation. I guess a logout will time out anyway if the task takes too long.

Thank you Kyle, however, I realize, it's incredible there is no way to execute a task before quitting the app. I easily run a task at launch but I can't run a task before quit.

Re: NSTerminateLater and thread
Return NSTerminateCancel when applicationShouldTerminate calls ExecuteLogOutTask to be performed in a secondary thread. At the end of your ExecuteLogOutTask method, call something like [myApplicationDelegate performSelectorOnMainThread: (logOutTaskDidFinish) withObject:nil waitUntilDone:NO]. Then, in logOutTaskDidFinish, call NSApplication's -terminate: method and set a flag indicating that ExecuteLogOutTask was already executed. The next time applicationShouldTerminate is called, return NSTerminateNow if this flag is has been set so ExecuteLogOutTask is not called forever.

NSTerminateLater and thread
I would like my application executes a given task before the log-out.
