Anyway, if you want try the full 1.55MB region you dumped earlier to see it doesn't accept region images but only Update ones for some weird reason.

My full-me-region image (1,55 MB) worked fine as well! Have just flashed it. Seems like there is a problem in this particular 9.5.41.. image, I don't know..

Thanks for the feedback Lipid. The previous official Intel ME region was v9.5.40.1892 which I have attached below.

Alright, this is strange. We'll wait until someone can create an update image so you can test that.

@All:

For those with a ME 9.5 consumer (1.5MB) system and firmware v9.5.41.1904 applied: Can you please make an update file of your ME firmware using the command FWUpdLcl -save UPD.bin and attach it for me here?

Thanks a lot! But it also didn't work. The same Error 8746: Firmware update not initiated due to invalid image length. Just to compare, your dumped update-image is 1,19 MB, mine native from Mac is 944 KB.

My dump ends on the offset line EBFF0, while there is still a lot of code in yours dump on that line till the end of the image.

Bottom line: ME firmware on Macs is not upgradable in its traditional way which is described here on the 1st page. Seems like Apple is really using some custom-build images for its ME firmware.

First of all, thank you very much RimZ for your firmware update file. It seems that indeed the ME is different, but I still don't believe it's MAC-specific as you said. It could be different FITC settings causing that. Regarding the $SKU number of each given firmware:

ME v9.5 1.5MB Production SKU: 04 00 00 00 60 9A 11 B1 13 22 00 00
ME v9.5 1.5MB from RimZ SKU: 04 00 00 00 60 9A 11 B1 13 22 00 00

ME v9.5 5MB Production SKU: 04 00 00 00 6F DA FF BD 0A 43 00 00

ME v9.5 1.5MB MAC SKU: 04 00 00 00 40 1A 00 11 23 22 00 00

So RimZ's file is indeed what we asked, the 1.5MB version.

@Lipid: What exact MAC model do you have? I'd like to see it's specs and hardware, that's why I ask.

@lordkag: Do you think the $SKU can change as a result of different FITC configuration and does not only rely on whether it's a 1.5MB or 5MB image? Maybe different FITC settings produce a different SKU variant. For example, could there exist 2 types of 1.5MB SKU?

Apple would need to ask Intel for any modification, since only them can sign the ME firmware. What could they ask that can't be changed in the settings and how would they know it, without Intel source code? The firmware should work in theory, the error seems to be in the image length.

By comparing the settings in FITC with 9.5.41.1904, I see no major difference. Also, the SKU wouldn't make any difference, since FITC only offers Premium and Mainstream. Apple ME is just a variant of Premium SKU.

By comparing saved and region dumps, it would seem that in 9.5.x firmware you can obtain an update image by just cutting from $MN2 sections until the end. Rimz saved image also confirms this. If that image didn't worked, then it might be more to it.

I don't have an older ME to compare, but Apple might have asked some portions to be removed from ME. Thus, not the entire image length is the problem, but individual sections are larger than expected by Apple. Only from another Mac you could try to take the ME, but it seems that is the last image in latest Mac firmwares: 9.5.3.1526 mobile and 9.0.5.1367 desktop.

Indeed at ME 9.5 you can make update images very easily just by cutting after the first $MN2. It's funny how Intel changes that from ME to ME. For example this is not the case with ME6 & ME8 from what I've tested. They used to have RSA protected headers in the beginning.

I thought that it has to do with Premium/Mainstream/No Emulation as well but changing that from FITC and rebuilding the whole image + ME did not change the $SKU identification. The $SKU probably determines the size (1.5MB or 5MB) instead of Premium/Mainstream/No Emulation etc. Maybe Apple has a special requested size other than 1.5MB or 5MB? Sounds silly even for Apple but you never know.

So I guess you have modern Apple computers (laptop, desktop) and that's how you know this is the "latest" ME Apple ever distributed with their systems?

I don't have other "MAC" ME images but if it helps I have v9.5.3.1520 1.5MB firmware which was probably the exact previous one before v9.5.3.1526. Using the aforementioned method (cutting) I also made the UPD file for quick comparisons. Can you make something out of it (attached file)?

I think the SKU determines a subclass of the Premium/Mainstream, but I don't really know.

No, I don't have a Mac, but the firmware can be found here. You just have to digg deep with 7z until you get a *.scap file, which is the firmware used for updating.

Based on the image you provided, it seems that Apple/Intel removed some portion of code.

Yes, I totally agree with you. There are definitely some cuts of code portions in my original me-dump. If you open it in hex-editor and compare the amount of empty 'FF'-space with the saved dump of 9.5.41.. provided here by Rimz, you will notice that there is much much more of empty space in mine dump.

And even MEinfo shows that there are only 2 firmware capabilities, while others usually have at least 3 or 4 of them:

Probably that's why it won't let me update this new firmware. It just doesn't want to accept all of these unnecessary code-portions.

I noticed that detail the first time you posted a picture of MEInfo but to my current knowledge this "list" can be adjusted easily via FITC to reflect the correct parameters and enabled features for each hardware & software configuration any given OEM desires. For more info look at my reply to lordkag below.

Based on the image you provided, it seems that Apple/Intel removed some portion of code.

I didn't know Apple has UEFI/BIOS updates somewhere, interesting. Still, I searched all of them with 7zip and indeed the only ME firmware that you can find (.raw files) is Desktop v9.0.5.1367 and Mobile v9.5.3.1526. The mobile v9.5.3.1526 firmware cannot be found anywhere whereas the v9.0.5.1367 one is everywhere. Unfortunately I could only find a 5MB region and not a 1.5MB in order to do an apples to apples (LOL) comparison between the MAC and Intel production firmware.

So then I decided to try and reproduce the MAC v9.5.3.1526 firmware using FITC and the exact previous Intel ME v9.5.3.1520. So I changed all FITC settings according to the MAC image and rebuilt a new v9.5.3.1520 ME with MAC configuration. It got me nowhere, the result still resembles the Intel image a lot more than the MAC one. My original thought was that if I disabled the same ME Features as seen at the MAC firmware, I would end up with a similar smaller file with some parts missing as lordkag and I previously observed. No matter what I tried though I couldn't replicate the missing partitions of the MAC image.

I cannot look into this anymore as it seems only Intel & Apple can produce such firmware. However, if anyone wants to look into it further I have attached below all needed images (9.5.3.1520_1.5MB_RGN, 9.5.3.1520_1.5MB_RGN_MAC-TEST, 9.5.3.1526_1.5MB_RGN_MAC, 9.5.41.1904_1.5MB_RGN, 9.0.5.1367_1.5MB_RGN_MAC). Bundled together is also FITC v9.5.12.1676 which can also be found at the original topic of course.

Conclusion: At this point my best guess would be that indeed Apple has requested Intel to make a special ME firmware just for their machines and normal/production images cannot be used for updating Apple computers. If that's indeed the case and since FITC does not seem capable to output a "MAC image" manually, all Apple users (the extremely small percentage that actually cares anyway) will have to rely on other MAC ME dumps or official UEFI updates in order to keep their ME somewhat updated.

Hi there! Today im flash my MSI H87-g43 mother board with bios and ME(1,5M) from Z87:

it works, but I expected unlocking the CPU multiplier
Chipset is still recognized as the H87, although all that could have flashed... Can anyone clarify the situation? What do you think is at all possible to unlock the cpu multiplier?
