MacMost Now 862: Mac OS X Cat Names Apple uses cat names to represent versions of OS X. It is important to know both the cat name and the version number of OS X that you are using. Sometimes you will hear or read the cat name, and sometimes the version number. So knowing which ones match which is important. Note: The headings on this list indicate the Macintosh System bundle names; the bullet points indicate the version of the System File included in that bundle. This is to make it clearer for people searching for specific bundle versions as opposed to System File versions. Finder File versions are not indicated. 1 Classic Mac OS 1.1 Macintosh System Software (0 - 0.3) 1.1.1 System File 1 1.1.2. Apple uses cat names to represent versions of OS X.

As discussed in previous blog Distributed notifications work as follows :
1. A notification center manages the sending and receiving of notifications. It notifies all observers of notifications meeting specific criteria.
2. The notification information is encapsulated in NSNotification objects. Client objects register themselves with the notification center as observers of specific notifications posted by other objects.
3. When an event occurs, an object posts an appropriate notification to the notification center.

Posting a distributed notification is an expensive operation. The notification gets sent to a system wide server that then distributes it to all the processes that have objects registered for distributed notifications. The latency between posting the notification and the notification’s arrival in another process is unbounded. In fact, if too many notifications are being posted and the server’s queue fills up, notifications can be dropped.
