However, despite the obvious advantage, a Mac running any OS X version later than 10.2 generally doesn’t need to be defragmented. This is because OS X and macOS have their own built-in Apple Mac utilities that clean up fragmented files from the hard drive. Therefore, for most users, it eliminates the need to perform a regular defrag. But there is an exception to every rule, and in a few rare cases, a defrag for Mac can make a difference.

When do Macs need to be defragged?

If your hard drive is more than 90 percent full, the macOS may have problems with automatic defragmentation routines. This situation is common for multimedia creators who produce plenty of large files in pro tools like Adobe Premiere, Final Cut, or Photoshop.

Therefore, if you have hundreds or even thousands of large (1GB and larger) movies, audio files, or creative documents, you should consider removing them to free up the storage. Another alternative is defragging a Mac.

Concerning the first option, there is a fast and safe way to remove unnecessary files from your Mac — a powerful app CleanMyMac X. It finds above 74 GB of junk on an average computer, including old and large files, app leftovers, and system clutter.

However, if you still wonder, “How do I defrag my Mac?” read on. We’ve prepared all the essential guidelines for you.

How to defragment a Mac

One of the simplest and most user-friendly Mac defrag methods is to use a trusted third-party defragmentation program. But before choosing and installing the app, make sure to back up your data. Should something go wrong, you’ll be able to restore all necessary files easily. You can use Time Machine, iCloud, Dropbox, or any other external storage at hand for this purpose.

When choosing the defragmentation app, pay special attention to the compatibility requirements. Macs running operating systems older than OS X 10.2 are not compatible with the latest modern defragmentation software, so finding a relevant tool is challenging.

Once you’ve installed the program of your choice, open the utility and follow the instructions of a disk defragmenter for Mac. Give the process plenty of time to complete without moving your computer anywhere until the defragmentation is finished. Usually, you’ll need to restart your Mac as well.

Will defragmentation harm my HDD?

You may not worry: OS X defrag will not harm your HDD. As you already know, disk defragmentation can greatly speed up the traditional hard drive. It’s because HDD fragments all the data and stores it in multiple locations. And it may take quite a time to read the file with its pieces situated in different places. The procedure for arranging the data is not harmful to your HDD and aims to boost the computer’s performance. And while it is not advisable to turn to such extreme measures, defragmenting a hard drive disk is a safe procedure if, of course, performed accurately.

Why you should never defrag Mac’s SSD

The process described above is applied only to the hard drives. If you have a newer Mac with SSD (solid-state drive), you should never defrag its data. SSDs operate in a different way to a traditional HDD and already have a built-in automatic maintenance process. Current eventsmac's history definition. Therefore, it is not necessary to defrag a solid-state drive to boost Mac’s performance.

Furthermore, all defragmentation attempts can even hurt your SSD. 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. And that’s not what you need.

What are alternatives to defragment a Mac?

If your Mac is running slowly, you don’t necessarily need to defrag Mac hard drive. Sometimes it’s not your HDD that’s having problems. Therefore, try some alternative methods that may help you speed up the system without disk defrag on Mac.
