Recently there has been a debate regarding defragging Mac OS X and its disk optimization as an effective way for repairing disk permissions. Apple Company are even confident that defrag Mac OS X is not needed because the system already has its own optimization tool. According to the company you only need to defrag your system if you already have large files and your hard disk is already low. What makes defragmentation different from disk optimization?
In case your system already have large files it is necessary that you create backup of all your important files and applications. Then you can re-install your Mac operating system and restore your backup files back to the system. This is quite a time consuming activity but eventually will make your Mac system to run faster in accessing your large files. You can also use other utilities that will create a clone of your startup drive and then you can format the hard drive and restore the files back again. This is quite a faster remedy.
Mar 23, 2021 So while the need to defrag a Mac is fairly rare, it is still a useful process and could potentially help improve your workflow. How To Defrag Your MacBook Pro with HDD – Drive Genius Since you need a third-party tool to defragment a MacBook Pro, we decided to highlight Drive Genius, a well-reputed computer cleaning tool with an efficient. Defragmenting a Mac Hard Drive: Is It Necessary? How to Defrag HDD Step-by-Step. Thin out user files on the boot drive. Start with the largest files like videos. Mind that a full boot drive (more. Choose a blank powered external drive. A Carbon Copy Cloner will help to clone the OS X boot partition (Mac hard disk). This video is a tutorial on how to de fragment your hard drive on Mac computer. This not only shows you how to de fragment your hard rive but also gives you an invite into why you should defragment.
Mac Os X Defrag
Fragmentation is the process of splitting your files into multiple parts and storing it to different locations on the hard drive. However, files can be access easily in just one lump rather that seeking into two or three segments. This will more likely cause your system to slow down instead. The file systems are composed of different portions of free space that are separated from each other. When the hard drives is full of data then the file system will used smaller disk space instead and will result to split files into smaller chunks and then distribute it to different locations on the disk. This is already fragmentation process.
However Mac OS X’s HFS+ the file system is already protected from fragmentation this is because the file system under Mac will not used the space recently freed as much as possible and look for other areas where to store the files and other information. And another thing Mac OS X uses routine that will clump the smaller space in the hard disks into larger portions. And Mac OS X already performs its own defragmentation process which is known as “Hot-File-Adaptive-Clustering.” This greatly reduces the chances of fragmenting the files.

On the other hand, disk optimization is quite a different process form defragmentation. This deals with the organization of related files into logical groups in order to improve the performance of the system rather than splitting it into multiple chunks across the hard disk. Some of the common utility that performs disk optimization is the iDefrag that alters the arrangement of files in the hard disk in order to enhance its performance. This comes with pre-defined layouts that works for Mac OS X. This will eventually improve the performance of your system in the process.
How To Run A Disk Defrag Mac Os X
Some Mac users are often confused if they need to defrag their Mac OS X? Mac users already enjoy the benefits of using their Mac OS X because it is already built in with utility that performs automatic defragmentation process. However, most users would rather use the disk optimization process because it will enhance the performance of their system rather than defragmenting their files.

Delivering speedy and smooth performance, Macs are known to be fast and reliable. However, despite being considered close to computer perfection, Macs are not immune to slow-downs. Bogged down performance can be caused by a number of reasons. These include scattered empty clusters on the hard disk that had appeared as a result of multiple reads and writes performed. To deal with the issue on Windows OS, you would have to defragment your HDD, but can you defrag a Mac?
Does Defragmentation for Mac Work?
It’s no secret that macOS is different from Windows. Among other things, they differ in the way they approach writing files on disk. Windows breaks up all files when writing them into clusters, while OS X does not fragment the small ones. As a result, there is no need for defragging them.
On one hand, this eliminates the need for regular defragmentation. On the other hand, once in every few years defragmentation is still needed due to app installs, big updates and flow of other large files on your Mac HDD.
Things to Know Before Defragging a Mac
In order for you to keep the hard drive running at its top speed, it is recommended to keep your data on the first 50% of the drive. HDDs operate faster in the first half due to having more sectors on the track with less travel time taking the heads to reach them. Running a defraggler helps contain maximum of your files on the first 50% of the drive which results in it performing faster.

Defrag also provides a solution to some of the more serious hard drive performance issues like failing sectors on the drive. It is worth mentioning that it will not repair physically damaged sectors, but only solve the soft bad sector errors.
Defragmenting Hard Drive on Mac
Fully defragmenting your HDD is a fairly complicated thing to do on a Mac, though don’t let it stop you from doing so in the first place. After all, this should be done only once every few years and reclaimed drive performance will definitely be worth it.
Defragging on the Live System
Let’s get it straight, defragmenting your drive will require a third-party application as Apple does not provide any native defrag tools.
Hands down, running defrag software on live system is the quicker way of getting it done. It is the one that’s riskier too. The drill is, no matter how good the software is, you always run the risk of something not going as intended, and if it does — you’re stuck. At this point, making backups just goes without saying.
Essentially, to defragment your Mac’s hard drive you will have to:
It’s also worth noting that this method does not guarantee that you will defrag your disk in its entirety.
Defrag Using External Clone
Those of you who are willing to take the high road and invest more time towards achieving reliable results, will favor this approach.
Instead of trying to defrag a disk from within the system itself, this method will have you create a clone of your current HDD, wipe the slate clean, and import things back, yet this time in the right order fitting all the clusters.
To make it happen:
This may take significantly longer, however, it is worth the time spent to confirm your hard drive working to the best of its ability.
Can You Defrag a Mac SSD?
The introduction of solid state drives has brought in significant improvements in read and write speeds. There is no surprise in Apple making a move to swap out HDDs for SSDs in their computers. Besides improved read & write speeds, SSDs feature trim commands which inform the OS how to treat blocks of data and when to wipe it internally. In other words, TRIM provides built-in self-maintenance processes that do make a world of difference as they nullify the need for defragmentation.
Moreover, defragging an SSD does it more harm than good. Solid state drives operate differently from a traditional hard disk and have limited erase cycles. Defragmentation attempts to reallocate data and puts your drive through multiple reads and writes. Because SSDs feature their own maintenance scripts, attempting to defrag your drive will only reduce its lifespan.

To draw the line, defragmentation will only benefit your Mac if it’s still got a hard drive in its heart. Running the full cycle every couple of years will help squeeze out more performance out of your HDD. On the contrary, defragging an SSD will show no positive result and only hurt its longevity.
