Interesting. In my autobuild[0] tool I used the FSEvent api to monitor filesystem notifications. This article prompted me to revisit the documentation, to make sure I'm not doing anything too stupid. The documentation clarifies: The file system events API is also not designed for finding out when a particular file changes. For such purposes, the kqueues mechanism is more appropriate. The file system events API is designed for passively monitoring a large tree of files for changes. The most obvious use for this technology is for backup software. Indeed, the file system events API provides the foundation for Apple’s backup technology. So the FSEvent api is more suitable for my use case, but it is useful to know this if I happen to have a different use case in the future.
