What is partitioning?
A partition on an iMac refers to dividing the storage space of the computer’s hard drive into separate sections.
Each partition is like a separate disk drive, with its own file system, and can be used to store different types of data or run different operating systems.
For example, you might partition your iMac’s hard drive to have one section for your Mac OS operating system and applications, and another section for storing your personal files and data.
Alternatively, you could create a separate partition for running a different operating system, such as Windows, alongside macOS.
Partitioning can be useful for organizing data and improving system performance by isolating specific types of data or applications.
However, it can also have some drawbacks, such as reducing the overall available storage space and making it more difficult to resize or manage partitions in the future.
