Summary: The blog explains the procedure to create a partition for installing the newly installed Mac OS Sierra on a separate partition on the drive. It also describes the steps for users to switch to the previous Mac OS X El Capitan version. Mac OS Sierra Public Beta has arrived and with this, discussions over installing and testing the impending software have also begun.
Even though the long wait is over, users are still skeptical about switching their system to the latest version just to test its new features. If you do not have a second Mac for testing this beta version, you can still manage to test the latest version without compromising on the user data. OS Sierra can be installed on the same machine running El Capitan by partitioning the hard drive via built-in Disk Utility. How the tool works? This integrated tool will split the hard drive into partitions and then install the latest Mac OS Sierra distinctly so that it can be tested without affecting the productivity of the machine.
Note: While beta versions incorporate new features, they also contain pre-launch software bugs that can create issues in the long run. As these bugs can affect the functionality of the device, therefore, it is recommended not to use these versions frequently.
It is advised to use the beta versions with additional caution. Before you begin the recovery process, it is advised to take a backup of the hard drive so that the data can be recovered easily in case of drive failure or similar issues. The easiest way to backup data is Time Machine backup.

Preparing your Fusion Drive Mac for the macOS High Sierra install Beta versions of macOS High Sierra made a change in the disk format of systems by converting them to use the new Apple File System. The initial release of macOS High Sierra will provide support for the new Apple File System as the default boot filesystem on Mac systems with all-Flash built-in storage. If you installed a beta version of macOS High Sierra, the Fusion Drive in your Mac may have been converted to Apple File System.
