Today a user here sent me a dump of a brick to investigate.

The interesting thing, there are 29 MemoryConfig entries and no SecureBoot certificates/PKs/dbs at all, just severe fragmentation.

Why I'm showing this? My theory that you can brick a Mac Pro just with the fragmentation of the NVRAM over time, see the multiple MemoryConfig entries accumulating, seems to be confirmed.

I'll investigate where/when exactly this happens now, I already have some insights about it.

Apple just 10.15.5 (19F96) released, downloading it now.

macOS Catalina 10.15.5 Update

macOS Catalina 10.15.5 introduces battery health management in the Energy Saver settings for notebooks, an option to control automatic prominence of video tiles on Group FaceTime calls, and controls to fine-tune the built-in calibration of your Pro Display XDR. The update also improves the stability, reliability, and security of your Mac.

Battery Health Management
• Battery health management to help maximize battery lifespan for Mac notebooks
• Energy Saver preference pane now displays battery condition and recommends if the battery needs to be serviced
• Option to disable battery health management
For more information, please visit https://support.apple.com/kb/HT211094

FaceTime Prominence Preference
• Option to control automatic prominence on Group FaceTime calls so video tiles do not change size when a participant speaks

Calibration Fine-Tuning for Pro Display XDR
• Controls to fine-tune the built-in calibration of your Pro Display XDR by adjusting the white point and luminance for a precise match to your own display calibration target

This update also includes bug fixes and other improvements.
• Fixes an issue that may prevent Reminders from sending notifications for recurring reminders
• Addresses an issue that may prevent password entry on the login screen
• Fixes an issue where System Preferences would continue to show a notification badge even after installing an update
• Resolves an issue where the built-in camera may not be detected when trying to use it after using a video conferencing app
• Addresses an issue for Mac computers with the Apple T2 Security Chip where internal speakers may not appear as a sound output device in Sound preferences
• Fixes a stability issue with uploading and downloading media files from iCloud Photo Library while your Mac is asleep
• Resolves a stability issue when transferring large amounts of data to RAID volumes
• Fixes an issue where the Reduce Motion Accessibility preference did not reduce the speed of animations in a FaceTime group call

Some features may not be available for all regions, or on all Apple devices.
For more detailed information about this update, please visit: https://support.apple.com/kb/HT210642

@tsialex and co., couple questions if you have the time (=

- When we check if a ROMTool export has been corrupted, opening the bin in TextEdit: it's usually all these crazy characters, and by searching "Secure", if we get a match, we should worry. Is there a guide or a thread dedicated to what happens / is recommended to do, if we *do* find a match examining the big ole' cMP's little dumps? Luckily I'm still safe, but just in case.

- Any point in running ROMTool on a modern MacBook Pro too? I did out of curiosity and tried to dump, but got an error. A day later, VirusBarrier Scanner gave me 2 alerts related to it (pic below) what do you think?

While it works, this is not the correct way. Install binwalk and use it to check.

There is no guide on the clean up, since there are several checksums and free space indicators that need to be set when you do any edits on the NVRAM volume. You can use the OpenCore NVRAM clean up if you have SecureBoot inside just one NVRAM store. If you already have two, you need a manual clean up.

Macs released around 2013 are UEFI and support UEFI Windows installs. UEFI Windows is a problem only with EFI1.10 Macs and it's not a problem itself but a trigger for fragmentation, the real problem.

SecureBoot certificates/dbs/PKs trigger the fragmentation that corrupts the BootROM because it requires so much space inside the NVRAM volume.

Normal, any AV will mark directhw.kext as a false positive, in this case.

I got curious today and decided to dump my MacPro4,1->5,1 BootROM (144). It's currently running Mojave and UEFI Windows 10 with OpenCore. I've had this thing for 5 years now and I remember having a UEFI install of Windows in the past, but luckily I don't see any certs in the dump. I am concerned about the "XML document, version: "1.0"" line. @tsialex should I be worried and does anything else seem problematic? Thanks!

Normal, it's the IASInstallPhaseList.plist, a log that it's created every time you open Recovery or macOS installer to track Recovery/macOS installer completion.

The problem is to have more than one, when you have two or more, you have a fragmented NVRAM volume.

I apologize if this question has already been asked but I have a situation where I need to revert back to The original bootrom on a macpro5,1 from 144 to 007F. I have a second macro5,1 that still has original bootrom 007F. Can I use bootrom to dump that rom and use bootrom to flash that to the other macpro5,1 logic board or that won’t work and why?

The reason why I’m doing this is because the latest bootrom has an issue with a PCI express card that I’m using to connect to an instrument and that instrument requires an older bootrom. I believe one of the later bootrom’s adds features to the PCIe bus that this PCIe card must not like. That 2nd macpro5,1 logic board is bad and bought another one off ebay but it has the latest bootrom.

Does the bootrom have unique information on each logic board like a PC bios or would one bootrom work in different Macpro5,1 logic board bootrom?

Answered several times, search is your friend.

BootROMs are unique, you can't use a dump from one Mac to another. When you use a BootROM from one Mac Pro on another you are cloning it. Apple detect this clones, since the MACAddresses are not stored inside the BootROM, and blocks iCloud/FaceTime/Messages.

Mac BootROMs are a lot more complex than PC UEFI firmwares or BIOS, Apple saves much more unique serialising/tracking data inside than a PC.

If your theory about the way the PCIe slots are initialised since 138.0.0.0.0, is correct, install PCIe tools and downgrade the slot that your card is installed back to PCIe v1.0. Someone made a script for this some time ago on another thread.

still searching for this tool. I have confirmed the latest bootrom breaks this PCI express card. I actually have a macpro4,1 and replaced it with a 4,1 logic board and the eBay seller updated the bootrom to 144... I am still searching for this tool in desperation.

Search for threads with setpci, you want the reverse of people usually want, set MP3,1 PCIe slots from the default PCIe v1.0 to v2.0, but it’s exactly the same process.

Screen Shot 2020-06-09 at 20.33.55.png


Anyway, you can always pay a firmware engineer with Mac Pro experience to reconstruct your BootROM image back to MP51.0089.B00, the last version without the PCIe v2.0 default.

Hi @tsialex

I was hoping you could check my BootRom that I have extracted for my MacPro5,1 - I think it has the Security Certificate on the NVRam? But to be honest I'm not 100% sure what I should be looking for, and If I do find it how to fix the problem?

I'm 99% sure I have installed windows using UEFI so wouldn't be surprised if the rom has the issue.

My goal is to install 144 without a Metal GPU and then run Windows 10 (legacy)

Thanks for your help!
