Enlarging a volume
If you have multiple volumes on a disk and one is running out of space, you may be able to enlarge it
without losing any of its data.
To enlarge a volume, you must delete the volume that comes after it on the disk, and then move the
volume’s end point into the freed space. You can’t enlarge the last volume on a disk. You can see the
order of the volumes in Disk Utility by selecting the disk, clicking Partition, and looking at the Volume
Scheme list.
All data on the deleted volume will be erased. Be sure to back up your disk’s data before you begin.
To enlarge a volume:
From the list at the left, select the disk that contains the volume you want to enlarge, and then click
Partition.
In the Volume Scheme list, select the volume beneath the volume you want to enlarge, and then click
Delete〔-〕.
The volume is immediately erased, leaving the space it formerly occupied available.
Resize the volume.
You can drag the divider at the bottom of the volume in the Volume Scheme list, or you can select the
volume, and then enter a value in the Size field.
If the enlarged volume doesn’t use all the space from the deleted volume, you can create new volumes
in the unused space.
To create a new volume, click Add〔+〕, select the new volume, and choose its name, format, and size.
Click Apply.
Disk Utility enlarges the volume and creates any new volumes.
