How to Add a Volume or Partition a Mac to Test macOS Big Sur?

Creating a partition or a new volume right on the existing hard drive makes the users eligible to manipulate all of the available storage temporarily as required. These processes make testing a new or beta OS quicker and easier on a Mac device. If you are partitioning the hard drive for testing your macOS, you will get a separate container on your existing hard drive, but it will be limited in terms of abilities and performance.

Here is how to add a volume or Partition on Mac to test the Big Sur:

Adding an APFS Volume on Mac

Follow these steps to add an APFS volume on Mac:

  • At the start, launch the Finder directly from the dock section of your Mac.
  • Then, choose the Applications option.
  • Scroll down the page and launch the folder Utilities.
  • Now, double click on the Disk Utilities option to launch the same.
  • Choose the APFS drive directly from your sidebar.
  • Type a particular name for your volume.
  • Then, choose the APFS format type you wish.
  • Now, select the Add tab.

If you wish to choose the specific size for your volume, then follow these straightforward steps:

  • Hit the Size options.
  • Now, type the Reserve Size option to ensure that the new volume holds a minimum amount of space.
