Default Stellar Partition Manager Software to Resize Mac Boot Partition without Data Loss

Disk Utility lets you initializing or formatting, partitioning, resizing, and managing your Mac hard drive during OS X installation. However, when it comes to resize Mac hard drive at a later time, I must say that the task it subject to your Mac machine. In other words, you can resize your Mac drive or any of its partitions later, only if you have an Intel-based Mac machine. Furthermore, you must be well-experienced in performing disk management related tasks in order that you can do that in a trouble free manner.

Resizing Mac Partitions

On your Intel-based Mac machine, you can anytime create, resize, and delete partitions, while the same is not facilitated on PowerPC-base Macs. The reason behind this fact is that Intel-based Macs use GUID Partition Table that allows doing these tasks, while PowerPC-based Mac machines use Apple Partition Table that does not permit any such task.

What if you fail to resize partitions on your Intel-based Mac? It may happen to you since this is a real-time partitioning scenario. Let me explain how and when it may happen:

While installing Mac OS X, you split up the drive in multiple partitions and keep some space unused for use later. You are done with the partitioning task and have installed the OS X as well. Later, you experience a need for enlarging the Mac boot partition for installing some more applications. You launch Disk Utility, but you do not see the free space shown in the graphical view of the hard drive in the Partition tab. This causes wastage of the drive space.

Likewise, if you delete one or more partitions on your Mac with Disk Utility, you get the space freed up for sure; however, you still cannot resize Mac hard drive or its partitions, as Disk Utility does not allow. All what you can do with Disk Utility in the name of resizing partitions is trim one partition and create a new one with the free space. Following are the steps to that without causing any harm to your Mac:

  1. Highlight your Mac hard drive in the left pane and go to the Partition tab to the right.
  2. Hold the right partition from its bottom right corner, and then drag upwards to trim it.
  3. With the space freed up below it, click the plus (+) button to add a new partition.
  4. Click Apply button to save the changes.

To resize Mac boot partition, you can also implement the aforementioned steps. However, in case you want to enlarge a partition, including the boot partition, using the free space either already available or you just created it by resizing one or more other partitions, Stellar Partition Manager is the recommended tool for Mac OS X. Following are the steps to follow for this:

Note: To resize Mac boot volume with Stellar Partition Manager, you have to create Bootable DVD for your Mac.

  1. Insert the Bootable DVD into the DVD drive, and then restart your Mac.
  2. Hold down the C key to boot from the Bootable DVD inserted.
  3. Accept the Licence Agreement, then and you see Stellar Partition Manager launched.
  4. On your Intel-based Mac, highlight your Mac hard drive to the left.
(The software displays the free space on the drive exactly where it is actually available.)
  1. If you see the free space below the Mac boot partition, then hold this partition from its bottom edge, and then drag it downwards to claim that space.
  2. This will add enlarge partition task to the Task To Do list. Click Start in the toolbar, and then Continue on the pop-up to execute it.
  3. If the partition below the Mac boot partition has sufficient amount of free space, then you can still enlarge the boot volume by dragging it downwards, as it automatically trims the below partition.
  4. Repeat step 6.

Note: You can resize any partition on your Intel-based Mac with Stellar Partition Manager.
