This thread is obsolete, we had 5 BootROM updates after MP51.0085.B00.

Please go to the
MP5,1: BootROM thread | 141.0.0.0.0



High Sierra update to 10.13.6 has the much awaited Mac Pro 5,1 BootROM firmware upgrade on the full Mac App Store installer.

Apple updated the Intel Xeon microcodes on MP51.0089.B00 BootROM to the April 2
Microcode Update Guidance
, but this microcodes are already superseded by July 3 Microcode Update Guidance.

You need to download and run the Mac App Store full installer.app for 10.13.6. Don't forget that a EFI supported GPU (Apple GT120/HD4870 with a 2009 or HD5770/HD5870 if a 2010/2012) is needed to do the upgrade of the BootROM. It will work with EFI flashed GPUs and For Mac models like Sapphire HD7950, eVGA GTX680 and Quadro 4000 Mac Edition too.

The updated microcode, while patched, should slow down PCIe SSD's. I'm in no hurry to jump onboard. 0085 is still working very well for my needs.

Not for me. Shows 1425 mb/s write and 1500 mb/s read with new firmware for single SSUBX.
[doublepost=1531206091][/doublepost]I found a simple way to output the microcode version only.

"sysctl -a | grep microcode"

From https://discussions.apple.com/thread/8232883.

"sysctl -a | grep cpu" appears to give the same output as "sysctl machdep.cpu".

Awesome Glad to see they fixed the Microcodes! it shows that Apple will listen to us :)

its interesting to note that it looks like they pulled the C0/C1 microcodes but no MacPro4,1/5,1 shipped with that stepping of Nehalem CPUs (only some Early Production Core i7 Nehalem CPUs and ES Nehalem Xeons are C0/C1 so it dosent matter any) but they did leave in the ES Westmere Microcode LOL

it will be interesting see how windows plays with this now official Apple microcode update (the MAS is still only showing 10.13.5 for me still :/ )

im also curious how W3690s and other 206C2 and 106A5 CPUs that intel say dont get patched are handled...

BTW while the new BR has Rev 30 seeing as your OS is loading 31 it means theres a even newer microcode it seems, I wonder what this one fixes and if we will get a 0090.B00 with it or not, or if this rev 31 Microcode is just for some OS level fix so not required to be in BR?

BTW if you want to just see your microcode version you can run

sysctl machdep.cpu.microcode_version

I prefer doing sysctl machdep.cpu

as it also tells us what CPUs we are dealing with here etc instead of having to waste more time asking that question if we are not sure :)

I managed to grab the 10.13.6 full installer finally and got my Mac Pro updated :)

can confirm the new microcodes :) I was also able to Boot windows (an EFI installation of windows 10) with no issues with this update so I wonder why windows breaks when we manually insert the microcode. Apple must of tweaked more then Just the microcode...

the InSpectre app was also reporting that I was fully patched as above. @h9826790 it would be interesting to see what your W3690 Mac Pro does with this Firmware update and if windows boot and if the inSpectre app reports your machine as fully protected or not? :)

http://valid.x86.fr/3h452f here is a CPU-Z validation of the newest 0089.B00 BootROM notice the updated Microcode :)

and just for reference heres a validation done while on 0087.B00 http://valid.x86.fr/s4hsqq

If I update using the full 10.13.6 installer, will I have to re-do the NVMe DXE injection?

Yes, every time you do any firmware upgrade, you have to re-do the NVMe driver injection. Unless Apple provide that natively in the new firmware.

LOL, man after years of nada we've had... what, like 4? 5? updates in the last 12 months?

Actually, I hope Apple takes their time with the next one, and in addition to the newest microcode, figures out how to get us boot screens with Mojave. NVMe and USB3 booting would be great too, but the boot screen thing is my biggest obstacle going forward (because I use FileVault on all my Macs).

Yep, 5 releases in less than 12 months and it'll need more…

10.13 DP5 came with 0083 with initial APFS support
10.13 DP6 came with 0084 with APFS support
10.13.4 came with 0085 (Mojave DP1/DP2/PB1/DP3/PB2 too)
10.13.5 came with 0087 missing the Intel Xeon microcodes
10.13.6 came with 0089 updating to the Spectre mitigated microcodes on the April 2 Microcode Update Guidance.

The July 3 Microcode Update Guidance updated again the microcodes used on MP5,1.

Edit: forgot 0083, thx @LightBulbFun

I just updated my mac pro (2012) to 10.13.6 through the App Store. However, my system firmware was not updated to 0089. It stays on 0087. Any advises would be greatly appreciated.

Mac App Store delta updates or even Apple Support ComboUpdates don't install Mac Pro BootROM firmware updates. You have to download the full Mac App Store installer for High Sierra 10.13.6 and run it.

Until now, Apple are only providing 10.13.6 full installer via Seed sucatalog. You can download it now via Installinstallmacos.py from GitHub.

Screen Shot 2018-07-10 at 17.04.06.png


To help people not used to downloading on GitHub, on installinstallmacos.py page, right click on Raw button and then Download Linked File.

GitHub_Raw_DownloadLinkedFile.png




Then run it with sudo:
Code:
sudo python Downloads/installinstallmacos.py

installinstallmacos.py will download all necessary files, it will take some time ~5.3GB, and will create a sparse image file with 10.13.6 installer, click 2 times to mount it.

Edit: to help people not used to GitHub/run python scripts.

You have to download the full installer to get the firmware update. Run the installer, the firmware update will launch, then when finished updating, quit the installer
