You do this by opening disk utility from your utilities. Let’s get into how to identify whether a Mac is a good candidate or not. The most effective thing you can do to speed up performance is to repair the permissions on the disk. But, again, not all Macs need to be defragged. There can be a few reasons why a Mac could be slow, but defragging may help. In general, it’s a good idea to defrag Macs or PCs with HDDs about once a month. Those people are generally creatives who use big files as. There is an exception to most every rule, and in this case it comes in when people have hundreds or thousands of videos, audio files, or multimedia files that are larger than about 1GB in size. Defragging also restores unusable capacity by reducing the space wasted between saved data. For most of us, HFC performs perfectly and you may never need to defrag a Mac’s hard drive. 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 system utility is included as part of MacOS and can be accessed by clicking on. ![]() ![]() ![]() 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. Hard disk drives (HDDs) store data on a spinning platter that’s divided into sectors.
