macOS that supports APFS file system viz. Sierra, High Sierra, Mojave, Catalina, Big Sur, Monterey & Ventura has an excellent feature to add new volumes to an existing APFS container. Unlike partitions, volumes inside an APFS container share free space among themselves, and the storage is allotted on demand.
You can deploy the newly added APFS volumes to install different APFS-compatible macOS versions. For instance, you can install the beta version of macOS Ventura, Monterey, Big Sur or Catalina on an APFS volume. Plus, if you need, you can easily remove the added volume from its container.
Add APFS Volume in Macintosh HD
You can use Disk Utility
to add a new volume to an APFS container. Using the (+) volume icon is not the
same as using the Partition tab present on the top panel of Disk Utility. This
is because partition creates a fixed size volume that can’t grow or shrink
unless you re-partition the drive.

Start-up Disk without Data Loss
To add APFS volume in an APFS container, perform the following steps:
Step 1: Press Command + Space Bar and type ‘disk utility’ then click Disk Utility to launch it.
Step 2: On Disk Utility, select an APFS container (say Macintosh HD) from the left panel.
Step 3: From the top panel, click the plus (+) icon to add volume to the selected container.
Step 4: On the “Add APFS volume to container” dialog box, type the name of the volume. Let the default APFS format be opted, or change it as per need.
Step 5: To set the storage size, click the “Size Options…” and specify “Reserve Size” and “Quota Size.” Use Reserve Size to set the minimum storage space for the new volume. Likewise, use Quota Size to set the maximum storage capacity for the same.
Step 6: Click the Add button to add the new volume to the selected APFS container.
Remove APFS Volume from Macintosh HD
When you don’t need an
APFS volume, you can use the (-) volume icon present on the top panel of Disk
Utility to delete the volume. This operation will remove the volume and all its
stored data. So if the volume has essential files, you must back them up to
avoid data loss.
To remove or delete APFS volume, perform the following steps:
Step 1: Open Disk Utility then select the volume that you wish to delete from the left panel.
Step 2: From the top panel, click the minus (–) icon to remove volume from its associated container.
Step 3: Confirm when prompted to remove the volume from the container.
