In this section, we will explore the macOS filesystem and storage together, as these are closely related concepts. First, we will examine general concepts about storage, such as formatting and the difference between disks, partitions, and volumes. Then, we will explore the default macOS filesystem, called APFS, and the additional filesystems it supports. Understanding these concepts is essential for you to decide when to partition disks, when to add volumes, which filesystem format to use, and how to make the most of the macOS default filesystem to save and optimize storage space.
These are the topics that we will cover:
- Understanding general concepts
- macOS partition maps (schemes)
- Understanding the macOS filesystem
Let's begin by reviewing general concepts before looking at the specifics of the macOS filesystem and storage.
Understanding general concepts
When talking about filesystems and storage, there are many concepts that we...
