Disk Utility User Guide

Partitioning a disk divides it into individual sections, each of which acts as a separate volume.

However, with APFS, you shouldn’t partition your disk in most cases. Instead, create multiple APFS volumes within a single partition. With the flexible space management provided by APFS, you can even install another version of macOS on an APFS volume.

Important: If you’re partitioning your internal physical disk because you want to install Windows, use Boot Camp Assistant instead. Do not use Disk Utility to remove a partition that was created using Boot Camp Assistant. Instead, use Boot Camp Assistant to remove the partition from your Mac.

Add a partition

Important: As a precaution, it’s best to back up your data before creating new partitions on your device.

1. In the Disk Utility app on your Mac, select a volume in the sidebar, click the Partition button , then click Partition.

   Internal storage devices appear below the Internal section in the sidebar. External devices appear below the External section in the sidebar.

   When you select a volume that already has data on it, the pie chart shows a shaded area representing the amount of data on the volume and an unshaded area representing the amount of free space available for another volume. Disk Utility also shows whether the volume can be removed or resized.

   Note: If you see a small volume with an asterisk, the partition is smaller than can be represented at the correct scale in the chart.

2. Click the Add button .

3. Type a name for the volume in the Name field.

   For MS-DOS (FAT) and ExFAT volumes, the maximum length for the volume name is 11 characters.

4. Click the Format pop-up menu, then choose a file system format.

5. Enter the size or drag the resize control to increase or decrease the size of the volume. Little snitch el capitan games.

6. Click Apply, click Partition, then click Continue.
