Dating back to 2002, when Apple launched the OS X 10.2, the devices had been developed to prevent file fragmentation but were able to defrag automatically. The core technology utilized by Apple is the Hot File Adaptive Clustering (HFC), which facilitates quick access to the read-only files in a hot storage zone on Mac. When the files are removed or deleted, Mac will automatically defrag them.

More surprisingly, the Mac devices are able also to detect whether the file is highly fragmented by themselves. If yes, they will automatically act to defragment it.
