Jun 25, 2016 My original goal when I started poking around Apple’s EFI implementation was to find a way to reset a MacBook’s firmware password. My preliminary research found references to a “magical” SCBO file that could be loaded onto a USB flash drive and booted to remove the password. The normal process workflow is to first contact Apple support.

Power adapters for Mac notebooks are available in 29W, 30W, 45W, 60W, 61W, 85W, 87W, and 96W varieties. You should use the appropriate wattage power adapter for your Mac notebook. You can use a compatible higher wattage power adapter without issue, but it won't make your computer charge faster or operate differently. If you use a power adapter that is lower in wattage than the adapter that came with your Mac, it won't provide enough power to your computer.
Mac notebooks that charge via USB-C come with an Apple USB-C Power Adapter with detachable AC plug (or 'duckhead'), and a USB-C Charge Cable.
Mac notebooks that charge via MagSafe come with an AC adapter with MagSafe connector and detachable AC plug, and an AC cable.
The images below show the style of adapter that comes with each MacBook, MacBook Pro, and MacBook Air. If you're not sure which model Mac you have, use these articles:

Apple 29W or 30W USB-C Power Adapter and USB-C Charge Cable
Apple 30W USB-C Power Adapter and USB-C Charge Cable
Apple 61W USB-C Power Adapter and USB-C Charge Cable
Apple 87W USB-C Power Adapter and USB-C Charge Cable
Apple 96W USB-C Power Adapter and USB-C Charge Cable
Make sure you're using the correct USB-C charge cable
For the best charging experience, you should use the USB-C charge cable that comes with your Mac notebook. If you use a higher wattage USB-C cable, your Mac will charge normally but you won't see an increase in charging speed. USB-C cables rated for 29W or 30W will work with any USB-C power adapter, but won't provide enough power when connected to a power adapter that is more than 30W, such as the 61W USB-C Power Adapter.
You can verify that you're using the correct version of the Apple USB-C Charge Cable with your Mac notebook and its USB-C AC Adapter. The cable's serial number is printed on its external housing, next to the words 'Designed by Apple in California. Assembled in China.'

About the MagSafe to MagSafe 2 Converter
If you have an older MagSafe adapter, you can use it with newer Mac computers that have MagSafe 2 ports using a MagSafe to MagSafe 2 Converter (shown).

* Adapters that shipped with the MacBook Air (Original), MacBook Air (Late 2008), and MacBook Air (Mid 2009) are not recommended for use with MacBook Air (Late 2010) models. When possible, use your computer's original adapter or a newer adapter.

You can get extra or replacement adapters with AC cord and plug at the Apple Online Store, an Apple Reseller, or an Apple Store.
A replacement adapter might not be the same size, color, shape, or wattage as the original adapter that came with your computer. But it should power and charge your Mac like the adapter that originally came with your computer.
If you need help using your MagSafe adapter, see Apple Portables: Troubleshooting power adapters.
If you're looking for a PowerPC-based power adapter, see PowerPC-based Apple Portables: Identifying the right power adapter and power cord.
EFI DXE EmulatorAn EFI DXE binary emulator based on UnicornCopyright © 2016-2019 Pedro Vilaca. All rights reserved.-This is an EFI DXE phase binaries emulator based on.Reference blogpost explaining how it works:.It allows to run EFI DXE binaries inside a Unicorn virtual nachine with a basic interactive debugger that allows to step and interact with the EFI code.It works by implementing basic EFI Boot and Runtime services. Not every service is yet implemented, such as services to load and locate other binaries. This can be done with extra work, since the core code to load binaries already exists, although it needs to be modularized.Can be used to easier reverse some EFI binaries that don't interact with hardware or graphical EFI interface.This tool was created to reverse engineer and analyse the EFI binaries related to Apple's firmware password reset described in this blog post,. So some stuff is configured/hardcoded for this specific goal (the sample ini file is configured with the required binaries).The debugger is still pretty basic but allows to view and modify registers and memory, step into calls or over them, and breakpoints. Unicorn has some limitations regarding this, such as problems changing the EFLAGS register inside a hook.
The hook implementation for breakpoints also has some limitations. These are due to the JIT used by Unicorn/QEMU.The debugger command line parser is pretty crude and definitely needs serious work to improve it. It works pretty well if we know what we are doing. It's based on gdb/gdbinit commands.Even with all its limitations this is a pretty useful tool for reversing some EFI binaries, improving a lot the reverse engineering process from a static analysis only (for us who don't have 6k JTAG based EFI debuggers).It's also a nice showcase of Unicorn potential and limitations. With further development it could be expanded to fuzzing and vulnerability discovery in firmware world.To retrieve the code and its dependencies.
Git clone -recursive 'No Makefile available, only a Xcode project but the code should easily compile in other Unix OSes with minor modifications if necessary.I have included a sample.ini file, the two target EFI binaries extracted from a MacBook Pro 8,2 model, and the SCBO file that was available around Internet. There is no NVRAM dump because I need to sanitize the one I have used.
You will need to modify the paths inside the sample.ini file.Enjoy,fG!
