What Is an EFI Partition?

EFI stands for Extensible Firmware Interface, which is primarily intended for IA-32 and Itanium architecture-based computers. In simple terms, an EFI partition is a partition on data storage devices like hard disk drives or solid-state drives used by computers. The EFI specification provides a model for the interface between the operating system and platform firmware.

When your computer boots up, UEFI (Unified Extensible Firmware Interface) loads files stored on the EFI partition to start the installed operating system and other various utilities. This means that an EFI partition plays a vital role in ensuring that your Mac can boot properly and load its system software correctly.
