Can I post a notification in a given queue and receive it on another? I want to use notifications to communicate different queues, but I'm not sure if this is safe...

1you can use it, but there are some advances solutions to synchronise the different threads as well like semaphores, locks etc... – holex Apr 12 '13 at 10:24

It sounds like your essentially asking the same question as [I answered here.](http://stackoverflow.com/a/13484491/927947) – NJones Apr 13 '13 at 15:22

No. Notifications are delivered in the same thread that they are sent from, this you will need to re-send it in some way to get the notification to your thread.

No.
Apple's docs on the subject say: "Regular notification centers deliver notifications on the thread in which the notification was posted. [...] At times, you may require notifications to be delivered on a particular thread that is determined by you instead of the notification center. [...] In these cases, you must capture the notifications as they are delivered on the default thread and redirect them to the appropriate thread."
The following documentation from Apple might help: https://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/Notifications/Articles/Threading.html#//apple_ref/doc/uid/20001289-CEGJFDFG
