| Description | The mac format, also known as "Apple Mac" or simply "Mac," refers to the file system and operating system standards used by Apple Inc. for Macintosh computers. Historically, Mac used the HFS+ (Hierarchical File System Plus), but Apple has transitioned to APFS (Apple File System) with recent macOS versions. |
| Technical details | HFS+ supports large files and volumes, offers better performance than its predecessor, and includes journaling for file system integrity. It allows file names up to 255 characters and uses Unicode encoding. APFS, optimized for SSDs and flash storage, provides improved performance, security, and reliability. Features of APFS include strong encryption, space sharing, file and directory cloning, snapshots, and fast directory sizing. |
