Defragment is the process to reorganize the files which are scattered stored on the hard disk. It removes the gaps between the recorded parts of the files, collecting them into a single whole part. Simply put, defragging a drive traditionally moves everything back in order and fills any holes that have appeared during its use. Therefore, defragmentation reorganized your computer and saves time to find and read the files and speed up your computer. Does Mac need defragment Generally speaking, Mac doesnt need to be defragged. Defrag My Mac OS X Versions LaterThis is simply because Mac OS X versions later than 10.2 file system were designed differently to Windows. Apple uses the HFS (Hierarchical File System), which provides a special function Hot File Adaptive Clustering, or HFC. The main purpose of this component is to automatically prevent fragmentation of disk storage. Its just rare. When updates, upgrades, installation or re-installation take place, you might need to defrag it once in a few years. When does your Mac need to be defragged The only real exception you need to defrag a Mac is when your hard drive has less than 10 percent free space.

If youre using a Mac that comes with an SSD (solid state drive), theres no point in wasting your time defragging as they already have a built-in maintenance process called TRIM.SSDs operating in a different way from a traditional HDD. Its flash memory used by a solid state drive has a finite lifespan because of the limited write and read cycles. And disk defragmentation is a process of reading the data from one place and writing it to another. So if you defrag SSD, you will perform thousands of write operations each time on the drive. It can speed up the degradation of a solid state drive and lead to its wear and tear.
