![]() ![]() This looks like the best match I could find for a fresh ME Region for my mac mini. Its compressed but by opening it up to the leaf level you can access the uncompressed "Raw Section", right click and extract body to a file. There is a section called "MeRegionUpdateVolume" in EfiUpdateDataFileGuid I was looking for a ME region for a Mac Mini, so I used Expand the DXE Volume and search for the DXE driver you want to replace. Expand the 'BIOS Region' and search for the DXE Volume, where the files of the Subtype 'DXE driver' are located (Tip: Use the UEFITool 'Search' option and enter 'DXE'). ![]() Mac2015002EFIUpdate.pkg/Scripts/Tools/EFIPayloads Open the source BIOS file with the UEFITool.

Note that a BIOS update by its nature will mean some modules will change (due to bugfixes/new features etc.) but this should at least let you know which specific parts changed and maybe even inspect them in detail.I needed an ME Region 8. ![]() In it against a list defined in ``efilist.json`` > chipsec_main -i -n -m -a check,efilist.json,uefi.romĭecodes ``uefi.rom`` UEFI firmware image binary and checks all EFI executables Unlock MacBook EFI Firmware Passcode Lock just in 1 clickiRemove development team presents Macbook EFI Firmware Password Unlock Tool. > chipsec_main -i -n -m -a generate,efilist.json,uefi.romĬreates a list of EFI executable binaries in ``efilist.json`` from ``uefi.rom`` The module will dump firmware image directly from ROMĬreates a list of EFI executable binaries in ``efilist.json`` from the firmware ``fw_image`` Full file path to UEFI firmware image. Some of the command line tools have been changing: UEFIDump was a tool that dumped info. And there are two codebases on Github, master and new-engine.

You likely are up to date, but this is how to check. The tools check apples entire catalog and then calculate locally if any updates are required. Alternatively, use the About This Mac command at the top of the Apple menu, and click on the System Report button.

Beyond Compare or even diff).Ĭhipsec project has a whitelist module which is intended to verify that the list of UEFI modules has not changed: UEFITool or the sister project UEFIextract: extract both images then compare using a standard file diffing tool (e.g. There are at least two options I know of to check for differences between UEFI ROM dumps: The contents of the firmware volumes containing code should not change between boots. Usage You can either Drag & Drop or manually enter Apple EFI IM4P file (s). The output comprises only final firmware components and utilities which are directly usable by end users. The dump is likely different due to NVRAM data (basically settings which need to be saved between boots or even BIOS updates, such as boot device, RAM timings, serial number/MAC address and so on).
