BEST GUIDE: Defrag Your Mac Using iDefrag

Degraded computer performance is a common phenomenon. Disk defragmentation is the most used option to optimize and speed up your computer, especially among Windows users. However, things are a bit different when it comes to Apple. Mac stores files on the largest available free space blocks. Additionally, Mac uses Hot File Clustering (HFC) to automatically optimize disks. HFC is a multi-staged clustering scheme. HFC records “hot” files on a volume (0.5% of the file system located at the start of the volume), and moves them to a place called hot space. These files are also defragmented automatically. Despite all this improvement, Mac’s disk drives are not completely immune to fragmentation. There are times when defragmenting your Mac’s disk can improve your system performance.

In this guide i will walk you through a great utility called iDefrag to defrag your Mac Hard Drive. This is the same utility used by the Genius Bar techs at Apple Stores to perform a variety of tasks. iDefrag also optimizes the disk by rearranging files to improve performance and speed.
