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.
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.
