Stellar Partition Manager is quick, easy, do-it-yourself software that manages the individual volumes (including the boot volume) of your Mac. It has a simple and user-friendly interface for smooth operation. Its compatibility with OS X 10.10 Yosemite and later ensures stable performance. The software handles all partition management tasks, such as creation, deletion, and formatting of volumes, as well as hiding/revealing a volume. Creating a partition utilizes the unused space available in other volumes, while deleting a volume frees overall space for other volumes. If the operations are to be performed on the boot volume, you can do it by creating a boot disc. However, data backup is always suggested to avoid any kind of data loss when operating on the boot volume.
