Apple has come up with a well-arranged Mac Disk Utility interface that will make enlarging/resizing of a Mac Volume to be easy.
Step 1. Navigate through your menu and open Mac Disk Utility.

Step 3. Then select Partition on the toolbar to resize the Volume of your choice using the Utility tool. A pie chart will open showing free space and space occupied by each Volume.
Step 4. For a volume to be enlarged, another one has to be deleted. So, choose the Volume you want to delete on the pie chart.
Step 5. Delete the Volume of your choice and tap the minus icon below the pie chart. The pie chart will give you a warning message about what you've done.
Step 6. If you're satisfied, tap Apply or tap Cancel to delete another Volume.
Step 7. Automatically, Mac Disk Utility will add up the freed space to the Volume instead of the deleted one. However, if you want to customize the Volume sizes, you can select the Volume, specify its size then hit Revert/Return. You can create a new Volume in the leftover space.
Step 8. Drag the Pie Chart to adjust the size of each volume. When the Volume is adjusted to the size you desire, click Apply, and that's it.
