Your Mac, be it a MacBook, iMac, Mac Mini or Mac Pro comes with a single partition irrespective of the storage size. But sometimes you need multiple partitions or at least two just to separate system data and applications from your personal data such as photos, videos and documents. Partitioning could also be useful if your OS gets buggy or corrupted and you want to reinstall it. You will only need to format the partition with OS in it while your data will be safe in the other drives. Moreover you can also use a separate partition to install the beta builds of OS X without messing up with your stable build.

In this post we will show you how you can create more than one partition on your Mac’s drive and use them for different purposes. Follow the simple steps below.
