Part 1: Why Do You Need to Delete a Partition on Mac?

Before learning how to delete a partition on Mac, it is important to cover the basics. Ideally, there could be different reasons for removing a Mac partition. Chances are you might have encountered one of these situations as well.

  • If you are reselling your Mac, then you should format its storage to protect your private data.

  • In case if the partition has been corrupted, then a quick format would fix the issue.

  • A lot of people format the partition to make more free space on their Mac storage.

  • You might wish to empty a partition altogether and merge it with another one.

  • If the partition has been infected by a malware, then formatting it would fix it.

  • Sometimes, users wish to erase a partition so that they can change its default file system.

  • It will also fix any disk related issue on Mac or end up defragmenting it as well.

Part 2: How to Delete/Remove Partition on Mac?

It doesn’t matter what kind of macOS version you have, you can easily use its inbuilt settings to delete disk partition on Mac. To do this, you can take the assistance of the Disk Utility component on macOS. Though, before you proceed and learn how to remove a partition on Mac, keep the following things in mind.

  • Since it will erase all the existing data on your Mac, it is recommended to take a backup of your important files beforehand.

  • In order to run the Disk Utility feature on your Mac, make sure that you have logged-in to the administrator account (or know the admin account details).

  • Make sure that your Mac’s battery is charged enough so that the formatting process won’t be halted in between.

  • Mac also allows us to review the disk partition, create logical separations, or defragment it. You can do these things without formatting the partition.

  • There is also a “First Aid” feature in Disk Utility that can repair Mac’s hard drive. If you are formatting your disk due to a malware or any other issue, then consider fixing it instead.

Now when you know the repercussions of formatting a partition, you are ready to learn how to remove partition on Mac. Firstly, you need to erase the partition completely and then remove it by reassigning its storage. While the process is the same for every major macOS version, the overall interface might alter a little.

Step 1 Erase a partition

If the partition already has some data stored in it, then you can’t remove it just like that. Firstly, you need to format it in order to erase its data. To do this, just go the Finder > System Preferences > Applications > Utilities. From the list of the available utility components, select Disk Utility and open it.

This will launch the dedicated Disk Utility window on your Mac. You can see the details of Mac’s internal drive or any other connected external source as well. Just select the drive or partition that you wish to erase from the left panel.

Step 2 Remove the partition

Erasing a partition is only the first step. After when all the existing data on a partition is deleted, it can easily be removed. In this way, you can utilize the newly obtained space and merge it with your Mac storage. Firstly, launch the Disk Utility component by visiting Mac’s Applications. Select the main hard drive of your system from the left panel. In most of the cases, it is either Macintosh HD or Fusion. This will display its partition on the right with different options on the toolbar. Click on the “Partition” icon on the toolbar to proceed.

This will display a graphical representation for the logical partition of your Mac’s hard disk. For instance, if it is a pie chart, then you can just click on the partition that you have just formatted. Click on the “–” (minus sign) at the bottom and confirm your choice to remove the selected partition.
