I am going to update the firmware on my cMP to allow booting off an NVMe M.2 SSD in High Sierra. To do so, I understand that I need to install the firmware using Mojave. My question is this: will the Mojave 10.14.5 installer attempt to reformat my HFS drive to APFS before it installs the firmware? I assume that it will not, that it will first update the firmware, then ask to install Mojave. Please advise. I do NOT want to reformat any drives to APFS or to install Mojave at this time; I only want to update the firmware to enable NVMe boot support. As an aside, it sure would be a lot easier and less confusing if Apple would simply allow straightforward standalone firmware updates as it did in the past rather than requiring they be handled during an OS install. Sigh.
Or at least not make the required set of installers almost impossible to download.…if Apple would simply allow straightforward standalone firmware updates as it did in the past rather than requiring they be handled during an OS install. Sigh.
Check Mojave black screens with RX 560/580 note on the first post.Thanks to the advice here I got a MSI RX 560, the one Apple recommends. I installed it, booted fine in Sierra, I then rebooted from the Mojave SSD but nothing, just a black screen. I installed Mojave, after High Sierra, as recommended, my BootRom is 144.0.0.0. But that was with the old card (R9 270X). What else can i try - it should work with that card, right? Do I need to install Mojave again, with this card installed?
You didn't need to replace the GTX 680 for the firmware upgrade, it's a METAL supported GPU.How can I force the firmware update without install OS?
Mi wife has a MacPro 5.1 2012 with Mojave 10.14.5 and firmware 141.0.0.0... 2 days ago I upgraded the graphic card (remove the gtx680 and installed RX580 8Gb) and from this moment I have to reset a PRAM to boot system... If I don't reset PRAM, never boot, system stay on a eternal black screen after the chime sound.
I try to follow the instructions of the first post for rx580 with black screen, but I don't have these extensions...
No, it's not how firmware upgrades work. You have to use the Mojave 10.14.5 full installer to do the upgrade.The processor is a W3680 (3,33Ghz 6 core mono processor) and I think that will be related because 144.0.0.0 solve an issue with those processors...
Can I put the 144 firmware in some system dir to do the upgrade?

Check the first post, all your doubts are answered there.
Like I said before, that's not how firmware upgrades work and what you describe don't work with Macs.I know it... Perhaps I don't write clearly...
I did the upgrade to have a better graphics card, not for the update.
I was read the first post before ask here... I don't want that three users explain me again what is wrote
I try to upgrade with the last Mojave 10.14.5 full installer (like I did with my 5.1 of the signature) but in my wife's computer didn't appear the message of firmware update, try to install again Mojave over the current Mojave installation...
For this reason my question is if exist other method of upgrade the firmware, for example putting the firmware files in root, power off and push power-on button till flash the led...
Like I said before, that's not how firmware upgrades work and what you describe don't work with Macs.
If you have a BootROM earlier than 144.0.0.0.0 and your Mojave installer don't ask for a firmware upgrade, you don't have the current Mojave installer.
I'll download again... Perhaps I delete the 144.0.0.0 Mojave installer version and keep the previous version... strange because I upgrade to 144 my macPro, but possible
Thanks!
What firmware version is currently installed on your machine? I looked back through a few posts, but couldn’t find where you mentioned it.
The full installer is over 6GB. If it's anything less than that you don't have the full installer.I'll download again...
What the heck......where did your case go...
You risked a lot doing this with a MP4,1>5,1. Netkas forum method overwrite the BootBlock and makes impossible to use Firmware Restoration CD.I went from b03 straight to 144 without issue.
DUDE - that's inspirational. I'm gonna do something similar - I've been wondering how to cram certain new technologies into my case. You've flipped my problem on its head. Get RID of the case and build the dream. I'll take photos when i'm done - SWEEEEEET!
