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.
