Apple File System was announced at Apple's developers’ conference (WWDC) in June 2016 as a replacement for HFS+, which had been in use since 1998. [11] [12] APFS was released for 64-bit iOS devices on March 27, 2017, with the release of iOS 10.3, and for macOS devices on September 25, 2017, with the release of macOS 10.13.
The Macintosh File System does not support volumes over 20 MB in size, or about 1,400 files. [citation needed] While this is small by today's standards, at the time it seemed very expansive when compared to the Macintosh's 400 KB floppy drive. Apple introduced Hierarchical File System as a replacement for MFS
Hierarchical File System (HFS) is a proprietary file system developed by Apple Inc. for use in computer systems running Mac OS. Originally designed for use on floppy and hard disks , it can also be found on read-only media such as CD-ROMs .
In Mac OS X Lion 10.7, logical volume encryption (known as FileVault 2) was added to the operating system. This addition to the operating system in no way changed the logical structure of the file system. Apple's logical volume manager is known as Core Storage and its encryption at the volume level can apply to file systems other than HFS Plus.
Unix File System: Mac OS X: This partition contains a Unix File System (UFS) and is used by Mac OS X, Mac OS X Server (Version 10.0 and newer) and various Unix-like operating systems. Apple_UNIX_SVR2: A/UX, Unix: Originally introduced for A/UX (Apple Unix operating system based on System V Release 2, hence SVR2) on the 68k, it was later reused ...
The native file systems of Unix-like systems also support arbitrary directory hierarchies, as do, Apple's Hierarchical File System and its successor HFS+ in classic Mac OS, the FAT file system in MS-DOS 2.0 and later versions of MS-DOS and in Microsoft Windows, the NTFS file system in the Windows NT family of operating systems, and the ODS-2 ...
Fusion Drive is a block-level solution based on Apple's Core Storage, a logical volume manager managing multiple physical devices. [6] [7] The capacity of a Fusion Drive is confirmed to be the sum of two devices. [6] [7] Fusion Drive is file system agnostic and effective for both HFS Plus and ZFS. [8]
Core Storage is a logical volume management system on macOS that was introduced by Apple to Mac OS X Lion. Core Storage is a layer between the disk partition and the file system. [1] Core Storage is the basis for Apple's Fusion Drive technology, [2] which presents several partitions on multiple drives as a single logical volume.
