Disk Utility In Mac Facilitates Dividing The Hard Drive’s Free Space Into Several Partition

 Generally, the Mac internal hard drive carries one partition with OS X installation and others storing different types of data.Disk Utility in Mac facilitates dividing the hard drive’s free space into several partitions. However, you can get partition creation at any other time.For instance,to enlarge any other existing volume or to install another operating system. Under this circumstance, what will you do to  get the free memory space? You can either resize other existing volumes or delete your data to free up the memory  to get the required amount of space.
Suppose you split your 500GB Mac hard drive into 5 (five) partitions, i.e. 100GB for OS X installation, 100GB for movies, 50GB for pictures, 100GB for personal videos, 50GB for music and videos, and rest of memory (around 100GB) to create a partition for storing other programs, such as software, games, etc. Later on, you noticed that the 100GB movies partition is almost full and you have more movies to save on it. Under this circumstance, an Intel-based Mac machine allows you to resize an existing Mac partition without data loss (to enlarge your movies partition). Refer to the following steps to resize your existing Mac partitions safely, and use the free drive space to enlarge another partition or to create a new partition:
Launch Disk Utility (Applications/ Utilities/ Disk Utility)
Select the hard drive you need to make changes on, and go to the Partition tab at the right.
Click a partition containing free space and drag it from its boundary or from its bottom-right corner.
(At the bottom-right corner, you will see three gray colored inclined lines, which you need to click and hold.)
Drag the partition upwards to shrink it, and you will see the increasing free space at the end of the last partition.
Similarly, drag other partitions for trimming the free space.
When you realize the required amount of free space has been trimmed, then click and hold the target volume’s boundary or bottom-right corner and drag downwards to enlarge it.
After acquiring the free memory, click Apply to fix the modifications.
Alternatively, you can use this free space to create a new partition by following the steps mentioned below:
Select the free drive space at the end of the last volume, and
Click plus (+) button below the hard drive structure shown in the partition tab
Now, click the newly built partition and set its properties, i.e. Name, Format, and Size under Volume Information area. At last, click Apply.
*You can resize other existing Mac partitions only if the hard drive is using GUID Partition Table, i.e. on an Intel-based Mac machine.
