In 2017, Apple then announced Apple File System or APFS in High Sierra. When 2002 welcomed Mac OS X 10.2, the system got even more intelligent at preventing fragmentation.Īfter a year, Hot File Adaptive Clustering went life, which distinguishes files that are often accessed but seldom refreshed and move them to a particular zone of the drive, defragging them during the process.

If a particular file is smaller than 20MB and has more than eight fragments, it will be automatically defragged.įirstly introduced in 1998, HFS+ could defrag files quickly because of Hot File Clustering. Mac’s primary reason why it shouldn’t be defragmented is that the file system, which is HFS+ initially and APFS more recently, does not allow defragmentation since it automatically defrags files if needed. If you are running on Mojave or High Sierra, and your file system has been changed to Apple’s more up-to-date APFS, you won’t have the option to utilize any third-party tools to perform defragmentation on your Mac because there is none available today that work.Your Mac runs on an SSD, not a hard drive.Let’s go!

If your Mac has an SSD rather than a hard drive, defragmentation will cause no significant benefits and will probably destroy your drive in the process.Defragging can cause more harm to the drive because the constant moving of files tires the drive out.

Since the launch of OS X 10.2 in 2002, Macs have been able to defrag automatically.

Macs don’t get the same experience with defragmentation the way Windows PCs are used to.

All things considered, here are various reasons why Macs don’t offer a defrag work: Apple, however, never included this feature in macOS. In fact, Windows 7 to 10 naturally defrags on a week after week premise. Windows has consistently had disk defragging software. Noticed that your Mac is running slow? You probably think back to the days when you used to own a Windows computer, and how defragging the hard drive speed up your computer’s performance by a lot.
