Newer Macs use SSDs and thus don't need to be defragmented. Note that this only applies to older Macs with an HDD. These two mechanisms prevent data from becoming fragmented. The HFS+ and APFS file systems that Macs use automatically defrag files using two processes named Hot File Adaptive Clustering and on-the-fly-defragmentation. Just keep a watch on apps that leak memory and if you notice any dip in performance, either quit that app or restart your Mac.įragmentation isn't a problem on macOS.
