Usually, after few months of usage, a Mac loses its good old speed and becomes a bit sluggish. This may result in taking unusually longer time for opening, copying, moving or deleting large sized files. Many users do not figure out the problem in their Macs and get worried. However, slow Mac problem is quite a common problem, which is encountered by almost every Mac user in some part of their usage. One of the most prominent reasons behind this slowing down of the Mac is the fragmentation of the system hard drive. Don’t worry! You can easily get over this problem with the help of any hdd defragmentation software.
There are many different possibilities behind the slowing down of your Mac machine. This can be virus/malware infection, file system corruption or OS malfunction. Sometimes, the Mac goes slow due to any contradiction with newly installed hardware/software. Another possible reason can be the filled hard drive. If you do not have any of these problems, it is quite sure that your hard disk has been severely fragmented, which making the Mac slower.
Now, let us see how the hard drive gets fragmented and why the Mac goes slow? When you create a new file on the hard disk, it takes some contiguous bytes, which is called as a single chunk of memory. While saving the file, the Mac OS searches for the first single chunk of memory that is either equal or greater than the size of that file.
Similarly, when you delete a file, the OS frees the memory chunk allocated to that file. The process of deletion creates a free space in between occupied memory chunks. With such several instances of file creation and deletion, the space in the hard drive gets completely scattered.
Once the free space in the hard drive gets scattered, it becomes hard for the operating system to allocate the required size of memory chunk to new files. This results in the breaking up of new files into multiple logical fragments before the saving operations. When you try to perform any operation on such fragmented files, the OS takes more time to locate all their fragments and load them into the memory before it can perform the action. This indeed makes your Mac look slower.
Unfortunately, there is no Mac option that can defrag the fragmented drives and you need to take the help of any third party hdd defragmentation software to do the job. These software provide distinguished options to defrag your entire hard drive, selected volume or only the fragmented files in the hard disk. Moreover, with simple and interactive graphical user interfaces, the software are pretty easy to use even for the users, who do not have much technical knowledge.
