Steps to Partition Mac OS Mojave Start-up Disk Without Data Loss

Advantages of having more than one partition on your Mac

Your Mac systems generally have one built in default partition called the Macintosh HD. However, you can choose to have more partitions on your Mac if you wish and there are several advantages if you choose to do so. For instance, if you have 2 partitions, one can be used for the OS and the other can be used to store your personal data. So, if your system crashes, your personal data is likely to remain safe since it is stored on a different partition.

In addition to data safety, more partitions also allow you to have multiple operating systems on the same computer, which can be advantageous in certain situations. Also, your hard disk performs better when divided into multiple sections rather than one big chunk.

Now that we’ve seen the advantages of having partitions, let us now see how to create a partition on your Mac OS Mojave startup disk.

Steps to create partitions on Mac OS Mojave without data loss:

Partitioning macOS Mojave

As a first step before partitioning, make sure you have a backup of all data in the hard drive and then proceed with the process. Creating a partition on your Mac OS Mojave requires that you enter recovery mode. To do so, switch ON your Mac system and hold the Command + R keys and then follow the steps below:

  1. From the recovery menu, choose Disk Utility
  2. Choose your startup disk from the list of drives shown; it is usually named Macintosh HD. If you don’t find it, go to View > Show All Devices and then choose your Start-up disk.
  3. Click on the tab named Partition
  4. Then click on the ‘+’ sign
  5. Adjust the size of the partition you wish to create by using the resize feature
  6. Assign a name to the new partition, choose a file system and then click on Apply

Now, a new partition with the specified name and file system format will be created. Please note that you can follow the same steps to partition Mac OS system with High Sierra or Sierra.

You can also partition an external storage device in the same way as you did the start-up disk, except that you don’t need to use the recovery mode. All you need to do is connect the external storage device to your Mac and open Disk Utility to continue with the partitioning process as described above.
