Partition

A partition is a logical section of a drive. Each partition can has its own file system. Unix tends to treat partitions as if they were separate physical entities.

Partition schemes
For drives to be formatted in HFS Plus (Mac OS Extended), Apple's own Disk Utility supports the following partition schemes:
 * (APM): Supports booting by 68k and PowerPC-based Macs.
 * (GPT): Supports booting by Macs with Intel processors or Apple Silicon. Also supported by recent versions of Microsoft Windows

For drives to be used by Windows (e.g. Boot Camp):
 * Master boot record (MBR): Compatible with most versions of MS-DOS and Microsoft Windows.

The Apple File System, which superseded HFS Plus, favors creating logical containers and volumes instead of partitions.
