How to get BIN file from clean MacBook? (SOLVED)

Hi, as I mention above how could I get BIN file from clean MacBook Pro retina late 2013 with EMC 2678. It could help me and someone else in the future.

Regards

Sorry for insufficient information
It is MacBook Pro retina late 2013
CPU 2.6 i5
Model A1502
EMC 2567

My question is any way to dump bin file from clean MacBook?
As far as I can see from this site is SPI programmer such as bus pirate. Or does anyone have that file?

It could be greatly appreciated for your help.

If it is clean macbook you can boot it. If you can boot the machine you can dump firmware by 'flashrom'

Little instruction:
1. Make sure that kernel loaded into kext-dev mode.

$ nvram -p
.... skipped...
boot-args kext-dev-mode=1
...
$

If 'boot-args kext-dev-mode=1' not seen, add it by command:

sudo nvram boot-args=kext-dev-mode=1

Check 'nvram' command output again and reboot the machine.

2. Take and unpack this archive ghostlyhaks.com/media/kunena/attachments/628/flashrom_10.10-r.zip into some folder.
You'll find kext driver and 'flashrom' executable inside. Set permissions to 'DirectHW.kext' driver by command:

sudo chown -R root:wheel ./DirectHW.kext
sudo chmod -R 755 ./DirectHW.kext

3. Load kext driver.

sudo kextload ./DirectHW.kext

You should not see any messages but you can check that driver loaded by 'tail /dev/log/system.log' command:

tail /var/log/system.log
Sep 23 17:58:36 ******** sudo[1603]: **** : TTY=ttys002 ; PWD=/Users/********/flashrom_10.10_recompiled ; USER=root ; COMMAND=/sbin/kextload ./DirectHW.kext
Sep 23 17:58:36 ******** com.apple.kextd[48]: kext-dev-mode allowing invalid signature -67062 0xFFFFFFFFFFFEFA0A for kext "/Users/*********/flashrom_10.10_recompiled/DirectHW.kext"
Sep 23 17:58:36 ******* kernel[0]: DirectHW: Driver v1.3 (compiled on Mar 2 2015) loaded. Visit www.coresystems.de/ for more information.

4. Get a dump
Check that you need to not specify '-c' option. Just run 'flashrom -p internal'. And read a firmware with: 'flashrom -p internal -r ./firmware_dump.bin'

thank you rileystudent i save it all ready.
I have tried token.paul instructions but got an error about signature something.

thanks again

I have tried token.paul instructions but got an error about signature something.

Seems that you don't loaded the system in kext-dev mode... Can you show an output?

SOLVED

Yes with token.paul adviced

Only for read. You can't write into protected regions but can dump from a chip.

Can you please make sure that bin file from DirectHW.kext and flashrom can be dump on another mac in the same specs.

Thank you

Not sure that clearly understand you question. If you mean that: is dumped firmware from one computer can be used on another same? Answer: Yes. But in this case donor machine will be 'cloned'. Flashed computer with that dump will have same serial number with donor machine as well as EFI password and customer's settings.

flashrom is just a tool. It reads chip with SPI programmer doesn't matter internal or external.

Technically, I have to change serial number in bin file as well as clear password before dump to another chip. Am I right?

Yes. If you have got a clean firmware dump you need change a serial only.

As far as I know EFI password located in $SVS blog.
How about serial number where are they located?

Thank you
