The only real exception to this is when your hard drive has less than 10 percent free space. The result of all these safeguards is that the Mac rarely, if ever, needs to have its disk space defragmented. If it is, the operating system will automatically defragment the file.

When you open a file, the Mac checks to see if it is highly fragmented (more than 8 fragments).

In the process of moving these files, OS X defragments them, and then stores them in the area of the drive that has the fastest access.

OS X and MacOS implement Hot File Adaptive Clustering, which monitors frequently-accessed files that do not get changed (read only), and then moves these often-accessed files to a special hot zone on the startup drive.

The process of writing the files to a new larger location defragments all of the files in the group. Simply put, Mac defragment moves everything back in order and can greatly speed up a slow system. As a result, the related bits are grouped, and loading files and programs take less time.

The Mac OS dynamically gathers groups of small files and combines them into larger areas on your disk automatically. To cut a long story short, defragmentation aims to boost a computer’s performance by reorganizing the data on your drive.

Instead, it looks for larger free areas already present on the drive, thereby avoiding fragmenting files just to fit them into available space.

The Mac’s HFS+ file system tries not to use recently freed file space on a disk.

OS X as well as macOS have their own built-in safeguards that prevent files from becoming fragmented in the first place.

For example, you may want to install Windows 10 on your Mac or set up Windows 10 in a virtual machine. The reason for this perceived oversight is that a Mac running any version of OS X later than 10.2 does not need to be defragmented. Defragment hard drive and optimize read processes. If you open up Disk Utility, you’ll notice that it doesn’t include a tool for defragmenting any of the drives connected to your Mac. Do I need to be concerned about this?Īnswer: Apple supplies a handy application for working with hard drives called Disk Utility.

I don’t see any way to defragment my Mac’s hard drive. How to Securely Erase Hard Drive/SSD or External Disk. I’m used to routinely defragmenting my hard drive in order to ensure top performance by my computer. Let’s get into how to identify whether a Mac is a good candidate or not.Question: I’m a Windows user who recently made the change to Apple and the Macintosh. But, again, not all Macs need to be defragged. To do this, the Disk Defrag utility identifies. There can be a few reasons why a Mac could be slow, but defragging may help. Intechs Disk Defrag utility is designed to speed up your Macintoshs access to files stored on your hard disks. In general, it’s a good idea to defrag Macs or PCs with HDDs about once a month. Defragging also restores unusable capacity by reducing the space wasted between saved data. This unsystematic storage also creates spaces between saved data on the disk that aren’t usable, reducing storage capacity.ĭefragmenting basically reorders the data on the hard disk and bunches those bits together, making it faster and more efficient to access save files. This creates inefficiency, as the mechanical arm accessing a file must move to multiple sectors to collect the various bits of data a computer needs to read and open it. Over time, the data for a saved file becomes fragmented, meaning parts of the file are stored on different sectors of the disk. Luckily, many third-party disk utilities (such as the. Hard disk drives (HDDs) store data on a spinning platter that’s divided into sectors. However, Apple dropped the ball on this one and didn't include a defragmenter with Mac OS X.
