Which file system is described as being used as the primary file system in Macintosh?

• A. APFS
• B. NTFS
• C. EXT4
• D. HFS+

Answer: (D)

Macintosh systems historically used HFS+, also known as Mac OS Extended, as the primary file system. It was designed to integrate tightly with macOS, supporting features important to Mac users such as metadata handling, resource forks, and optional journaling to protect against corruption. For many years this served as the default and most common filesystem on Mac computers, making it the go-to answer when asked about the main file system used in Macintosh. A newer development is APFS, introduced to optimize for solid-state drives and modern macOS features like clones, snapshots, and strong encryption. While APFS is now the default on recent Macs, the traditional primary file system described in many exam contexts remains HFS+. The other options correspond to Windows and Linux file systems, which are not used as the Macintosh primary filesystem.
