Now you know which partitioning map is which, the next time you insert an external drive or want to partition the built-in storage disk of the Mac, it will be easier to choose between the available options. It is currently used for Windows partitions formatted as MS-DOS (FAT) or ExFAT.

Introduced by IBM in 1983 to support the 10MB hard disk, the Master Boot Record is a type of boot sector developed for use with IBM PC systems. While Intel-based Macs generally boot from a GUID Partition Table, they are all able to start the operating system from APM and Master Boot Record (MBR) using the BIOS-Emulation called EFI-CSM. Starting with OS X Tiger, both APM and GUID partitions can be used for accessing volumes, but PowerPC-based Macs can only boot from APM disks. Used on disks formatted for use with 68k and PowerPC Macs, the Apple Partition Map is the scheme that defines how the data is organized. Non-Intel Macs won't support this bootable standard, hence the only option available to them is the Apple Partition Map (APM). As part of the Unified Extensible Firmware Interface (UEFI) standard, GUID is a bootable standard for systems with EFI firmware such as macOS. This is a standard for the layout of the partition table on a storage disk using globally unique identifiers (GUIDs). On every drive there are multiple partitions, and for this you will need a partition table or partition map – maintained by the operating system – to detail the status of the partitions. The fixed-sized subset of a disk drive treated as an individual unit by the operating system (in our case macOS) is defined as a partition. In this article we will explain what a partition scheme is and which one to pick when formatting a drive.

WARNING:Formatting the drive will erase all data on the drive, so you should copy any data you want off the drive prior to formatting.When you attach a storage disk to a Mac with the purpose of erasing or repartitioning it, you'll be presented with the option of selecting one of the three available partition maps: GUID Partition Map, Master Boot Record, and Apple Partition Map.

Set Format to Mac OS Extended (Journaled) Check step 2 to confirm Disk Utility is Showing All Devices. NOTE: If you don’t see Scheme, then make sure that all devices are showing and the non-indented entry is selected. Select the non-indented entry, you will see Media in the nameĬlick the button labelled Erase in the menu which will bring up this window.Click View in the upper left and select Show All Devices.To open Disk Utility - Open Finder > Applications > Utilities > Disk Utility
IMPORTANT: Reformatting the drive will erase all data on the drive, so you should copy any data you want off the drive prior to formatting. If you need to go between macOS and Windows then format your drive ExFAT on macOS
