Dump Request for MacBook 2016 was created by plutomaniac
Hello,
I am looking for a dump from the new MacBook Early 2016 (Skylake). Based on this , the model should be A1534 with an EMC of 2991. Any such model will do.
Thank you

Hi,
I have same model of macbook on my hand. Did you find any solutions how to read this kind of SPI, and do you have the picture of SPI locations for this model A1534 EMC 2991?
Thanks

Hi,
Thanks for the reply. I don't have a picture of SPI location or even the macbook at hand, but I am still looking for a dump from such SKL-based macbooks. Based on past Apple observations, you should be able to dump the full SPI image from within Windows (native, not VM). If you have such capability then let me know and I can give some quick and easy instructions.

this EFI chip is surface mount, and the clips for the debug header aren't widely available yet.
to interface, you can attempt to use a kadentech clip (or the like)
or you can remove the chip from the board
again, i stress against using the raspberry pi on 2015+ macs when connecting via the debug header

The reason the raspberry pi is unable to interact with specifically the 12" models is because by default a raspberry pi operates using a 3.3v line as VCC, whereas the 12" Macbooks require 1.8v. Though on each model of pi there is a spot that provides 1.8v. In my blog post about how to remove BIOS password from HP laptops I go into detail on how to achieve 1.8v on a couple pi models. Regardless though I would refrain from doing anything with 2015+ models (that do not already have appropriate documentation in the EFID repository) unless you know what you're doing.

This is very true... I find myself not drawing the distinction...
We should refrain from using the term "MacBook" colloquially as we have... before the introduction of the 12" MacBook in 2015, all MacBooks were more or less created equally with 3.3v EFI chips and one could use the term "MacBook" indiscriminately when referring to an old white, an air, or a pro.
Now we must be careful both using and interpreting the term "MacBook" as it designates a specific model.
I am guilty of this.

There is no way to know the origin of this DUMP, the serial was removed!

I have seen several EFI dumps from 2015+ macbook12" models. They no longer seem to contain the serial number.

If you open the DUMP, will see that this has "ssn" but was removed and placed all "FF" in place of the serial number!

Mystery firmware. Where is it from and what do you plan to do with it?

I do not want to do anything with this DUMP!
According to the friend "Dimon58" seems to be a DUMP of a MAC 2016!
But you will know if it is!

Thank you for the dump Dimon58. It is indeed a 2016 SKL-based MacBook dump based on the firmware inside.

The programmer added an extra 0x40 bytes at the end which can be removed. The actual size is 8MB, 0x800000
It also seems that Apple is now locking the Intel Flash Descriptor so the SPI image cannot be dumped from within an OS like Windows or Linux. The only way is the use of a programmer or software dumpers after unlocking the FD first by shorting the two audio chip pins ("pinmod").

Maybe the extra data it is because the OTP area, see datasheet, pag 11
Reading as mx25l6406e there is no extra data
