This is why Mac optimization software doesn't usually include defragging as a feature.

macOS automatically defragments the files that are stored in more than 8 different sectorsĭue to this working principle, macOS doesn’t usually need defragmentation.

macOS file system identifies often-used files and moves them into the hot area of the disk for fast access.

macOS gathers smaller files into the larger areas on the disk and automatically defragments the files inside the group.

Instead, it finds a larger area of free space to write a whole file there, avoiding fragmentation

macOS file system doesn’t use the recently freed space on the outside of the disk to store data.

Both of them have some features that make storing of files more effective: It uses two file systems: HFS+ (macOS 10.12 Sierra and earlier) and APFS (macOS 10.13 High Sierra and later). Due to this algorithm, Windows needs to be defragged from time to time.īut macOS stores files differently on a hard drive. Reading such a file takes more time because the system needs to access several sectors to read it. It means a file can be divided into 8 or more fragments, written into different drive sectors. This sometimes leads to significant fragmentation of a file. Windows tries to use the faster area of the disk and writes new data to the recently freed sectors in this area.

Why is defragmentation good for a PC but not for a Mac? However, for an SSD it isn’t beneficial and may be even harmful. This totally makes sense for an HDD where data is accessed with a physical movement of a magnetic head. This way it’s easier and faster to read a file. This process is called fragmentation.ĭefragmentation is a process of organizing files on a hard drive so that parts of large files are grouped together. The computer will store some of these big files in the free space at the edge of the disk until it’s filled up and then store the rest of your file elsewhere on your hard drive. What happens when you add a new big file? That’s why the data is usually written on the faster (outside) edge first and then makes its way to a slower inside part of the disk. Reading and writing data at the beginning of the hard drive is the fastest, and as you move inward, things get slower, since the needle needs more time to reach the data. To understand why disk defragmentation might be useful for an HDD, let’s find out how data is stored on a computer.Īs we mentioned before, data on HDDs is read and written on a rotating disk with a mechanical needle. Go to Storage What is disk defragmentation? Go to the Apple menu in the upper left corner of the screenĤ. It’s easy to check what type of drive your Mac has:ġ. This kind of storage device was introduced in a MacBook Air in 2008 and was increasingly used by Apple ever since. Among the recent Mac models, only certain iMacs come with HDDs.Īn SSD (solid-state drive) uses flash memory to store information and does not have a spinning disk inside.

How to find out whether you have an HDD or an SSDĪn HDD (hard disk drive) is an older type of storage device equipped with a rotating disk and magnetic heads, which read and write data to the disk. Will defragging a MacBook do it any good? Here’s a short answer:ĭo you have an older Mac with an HDD storage?ĭo you have a modern Mac with an SSD storage?

Can defragmentation harm a hard disk drive?.

Why is defragmentation good for a PC but not for a Mac?.

In this article we will answer the following questions: Get MacKeeper and optimize the productivity of your device in a few clicks! With the app, you’ll always be made aware of when your Mac needs optimization.

So it’s necessary to optimize your Mac’s performance regularly. The more you ignore optimizing your Mac, the harder it may become to correct its operation at a later date. It’s also not a magic pill to increase the speed of your Mac. Please, note that defragmentation is not the only way to optimize your Mac. So what should you do? Is there a way to manually defrag your Mac’s hard drive? Is it necessary to do so and is it safe? Let’s take a look. (However, it has Disk Utility and Apple Diagnostics to fix your Mac’s hardware).

Moreover, Windows OS has always included built-in defrag software.īut what if you’re using a Mac? macOS (previously Mac OS X) doesn’t come loaded with any sort of a disk defragmenter. If you are an experienced computer user, or you used to have a Windows computer, you might have relied on disk defragmentation as a way to optimize your computer’s performance.
