What file system does Mac OS use?

• A. HFS+
• B. NTFS
• C. ext4
• D. APFS

Answer: (A)

Mac OS has historically used HFS+ (Hierarchical File System Plus) as its standard file system. HFS+ served as the default for Mac OS X for many years, offering features like journaling and support for Mac-specific metadata. This historical association makes it the best answer when the question refers to the traditional Mac OS file system. It's worth noting that Apple later introduced APFS (Apple File System) and adopted it as the default for many newer Macs, especially on SSDs, starting around 2017. APFS is different in structure and behavior from HFS+, with features such as space sharing, fast directory sizing, cloning, and snapshots. Forensics across Mac systems must consider which file system was used on the specific device and time period, as data recovery and artifact locations differ between HFS+ and APFS. The other options map to non-Mac systems or newer Mac configurations: NTFS is Windows’ file system, ext4 is Linux, and APFS is the newer Apple file system.
