The GUID Partition Table (GPT) is a standard for the layout of partition tables of a physical computer storage device, such as a hard disk drive or solid-state drive, using universally unique identifiers (UUIDs), which are also known as globally unique identifiers (GUIDs).
This partition is used by Mac OS for the Macintosh File System (MFS), which was introduced with the Macintosh 128K in 1984. Apple_partition_map: partition map: Apple: The partition map is also a partition of its own. It can vary in size depending on how many partitions it may contain.

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 ]
TestDisk reads sectors on the storage device to determine if the partition table or filesystem on it requires repair (see next section). TestDisk is able to recognize the following partition table formats: [2] Apple partition map; GUID Partition Table; Humax; PC/Intel Partition Table (master boot record) Sun Solaris slice; Xbox fixed ...
English: Diagram illustrating the layout of the GUID Partition Table (GPT) scheme. Each logical block (LBA) is 512 bytes in size. Each logical block (LBA) is 512 bytes in size. LBA addresses that are negative indicate position from the end of the volume, with −1 being the last addressable block.
The GUID Partition Table (Globally Unique IDentifier) is a part of the Unified Extensible Firmware Interface (UEFI) standard for the layout of the partition table on a physical hard disk. Many operating systems now support this standard. However, Windows does not support this on BIOS based computers. [10]
