As files are moved, the system defragments them.Nearly all newer MacBook models come with solid-state drives (SSDs), which don’t need defragmenting. HFC groups frequently used read-only files together in a hot storage zone on the drive for quick access. Rather than save data to recently freed-up space like a PC would, Macs will place the file in a larger area with room to expand.The HFS+ and the more recent APFS file systems used by macOS come with built-in processes such as Hot File Adaptive Clustering (HFC) and on-the-fly defragmentation.
