Just like Windows, it also provides a seamless solution to partition hard drive on Mac or un-partition it as well. Mac has a dedicated Disk Utility feature that allows us to manage the hard disk (Macintosh HD) pretty easily. In this post, we will cover the same and teach you how to partition a hard drive on Mac like a pro!


Part 1: What Does a Partition Mean on Mac?

Ideally, partitioning a hard drive means similar in almost every operating system. It divides the total space of a hard drive into different logical separations. This helps us keep our data segregated into dedicated locations, protect it, and even run different firmware versions on it as well.

Part 2: How to Partition a Hard Drive on Mac?

If you have enough free space on your Mac’s hard drive, then you can make the most of it by creating new partitions. In case if there is no free space, then you can unpartition a hard drive on Mac beforehand. To make it easier for us to partition hard drive on Mac, the OS has come up with the Disk Utility feature. We can take its assistance to manage the overall hard drive of our system and arrange it into different logical separations as well. To learn how to partition a hard drive on Mac, simply follow these steps:

Step 1 To get things started, you need to access Disk Utility on Mac. Go to Finder > Applications > Utilities and launch the “Disk Utility” app from here.


Step 2 As the Disk Utility app will open, you can see the internal hard drive on the left panel, named as Fusion or Macintosh HD. If you have connected an external drive, then choose to view all devices.


Step 3 Simply select a source drive from here and click on the “Partition” button from the toolbar. This will display a graphical representation of the hard drive’s storage and partition.

Step 4 To create a new partition, click on the Add (“+”) button. In order to adjust the size of the partition, you can move the divider on the pie-chart.

Step 5 Subsequently, you can enter a name for the partition and choose its file system. Presently, Mac supports a wide range of file systems like APFS, exFAT, NTFS, etc.

Step 6 After confirming its size, just click on the “Apply” button and wait for a while as Mac partition manager would create a new partition on the disk.

Part 3: How to Unpartition a Hard Drive on Mac?

Apart from creating new partitions on Mac, the Disk Utility feature can also be used to unpartition it as well. For instance, if you have created a partition by mistake or would like to merge it with another, then Disk Utility can help you. It can erase the existing data on a partition and also delete the partition altogether. You can unpartition a hard drive on Mac by following these steps:

Step 1 Firstly, go to your Mac’s Applications > Utilities and launch the Disk Utility tool from here.


Step 2 Select the partition or the external hard drive that you wish to delete from the left panel. From the provided options on the right, click on the “Erase” button.


Step 3 As the following pop-up would appear, click on the “Erase” button to confirm your choice. You can also change the format of the partition from here.


Step 4 Great! You are almost there. Once you have erased a partition, you can easily delete it altogether. Go to Disk Utility and select the root drive (Fusion/Macintosh HD) from the left. Click on the “Partitions” menu on the right to explore the available space.

Step 5 From the visual representation of the drive, you can see the available space. Just select the partition you have made available and click on the minus (“–”) button to delete it.

Once you have deleted a partition, the space allocated to it can be used the way you like. You can merge it with another partition, split it into different partitions, or create a new partition.
