When Macs need to be defraggedĪre there cases when Macs still require defragmentation? Defragmentation is most useful when your Mac’s storage is near capacity.

Just like Macs, newer PCs running Windows 10 and later don’t require defragmentation. This is because of the fact that macOS has its own built-in Apple Mac utilities that can clean up the fragmented files from the hard drive.

Macs running macOS 10.2 and newer generally don’t need defragmentation.

You may want to defrag Mac devices, but unless it’s running an older version of OS X, the system should take care of disk fragmentation on its own. Do I need to defrag my Mac?ĭisk defragmentation is likely not necessary for modern Macs. Defragmenting gave the computer time and license to find associated files and reorganize the file system to keep them together. This meant computers found files slowly, and the entire system would, in turn, run slowly. Rather than keeping associated files together, the computer may have them scattered throughout the file system. But over time, deleting a file here or there meant random areas of space where computers could store those files. If you had a program that needed access to ten different files, the logical step would be to store them right next to each other so the computer could find them quickly. When a computer stores files, it places them wherever it has room on its drive.
