On Apple Mac computers using Intel x86-64 processor architecture, the EFI system partition is initially left blank and unused for booting into macOS. [13] [14]However, the EFI system partition is used as a staging area for firmware updates [15] and for the Microsoft Windows bootloader for Mac computers configured to boot into a Windows partition using Boot Camp.
HFS Plus or HFS+ (also known as Mac OS Extended) is a journaling file system developed by Apple Inc. It replaced the Hierarchical File System (HFS) as the primary file system of Apple computers with the 1998 release of Mac OS 8.1.
HFS is also referred to as Mac OS Standard (or HFS Standard), while its successor, HFS Plus, is also called Mac OS Extended (or HFS Extended). With the introduction of Mac OS X 10.6 , Apple dropped support for formatting or writing HFS disks and images , which remained supported as read-only volumes until macOS 10.15 . [ 1 ]
Boot Camp 4.0 for Mac OS X 10.6 Snow Leopard version 10.6.6 up to Mac OS X 10.8 Mountain Lion version 10.8.2 only supported Windows 7. [3] However, with the release of Boot Camp 5.0 for Mac OS X 10.8 Mountain Lion in version 10.8.3, only 64-bit versions of Windows 7 and Windows 8 are officially supported. [4] [5]
Classic Mac OS drivers partition Apple_HFS: Hierarchical File System: Apple_HFS: While normally a HFS or HFS+ volume for Mac OS and Mac OS X, it can also contain an MS-DOS formatted file system (File Allocation Table, which can be accessed by Mac OS and Mac OS X). Apple_HFSX: HFS Plus: This partition contains a HFS+ volume without a HFS wrapper.
The partition type (or partition ID) in a partition's entry in the partition table inside a master boot record (MBR) is a byte value intended to specify the file system the partition contains or to flag special access methods used to access these partitions (e.g. special CHS mappings, LBA access, logical mapped geometries, special driver access, hidden partitions, secured or encrypted file ...
Note: The column MBR (Master Boot Record) refers to whether or not the boot loader can be stored in the first sector of a mass storage device. The column VBR (Volume Boot Record) refers to the ability of the boot loader to be stored in the first sector of any partition on a mass storage device.
The concept of a universal binary originated with "Multi-Architecture Binaries" in NeXTSTEP, the main architectural foundation of Mac OS X.NeXTSTEP supports universal binaries so that one executable image can run on multiple architectures, including Motorola's m68k, Intel's x86, Sun Microsystems's SPARC, and Hewlett-Packard's PA-RISC.
