APFS Driver for macOS High Sierra

简体中文

APFS driver in macOS High Sierra, with the verbose logging suppressed.

Apple introduced Apple File System in macOS High Sierra. In order to boot to macOS from PC, you need to add the file system driver apfs.efi to your boot loader.

The original apfs.efi driver extracted from macOS High Sierra (/usr/standalone/i386/apfs.efi) has verbose logging and will display some flash messages before you boot into the loader. This repository provides the modified version (and also the original version) so that you don't have to edit the binary yourself.

10.13.1

In order to quiet the APFS.efi logging, patch the following in Hex Fiend:

Offset 0x2227e -> 0x55 to 0xC3

  • apfs.efi - logging suppressed
    • MD5: bbdfcc6e4998401aa942b93992a7282e
    • SHA1: 324e81abc51620dab303976a8f739c66283ce117

This works in terminal:

sudo perl -i -pe 's|\x00\x74\x07\xb8\xff\xff|\x00\x90\x90\xb8\xff\xff|sg' /path/to/your/APFS.efi
