MVC EFI V2 coming for Maxwell and Pascal cards AKA, don't run recent nvidia uefi updater on your Mac flashed cards.
On June 4th, Nvidia released an update to enable DP1.3 and 1.4 on Maxwell and Pascal cards.
This includes everything from GTX750 on up. This is not a life-or-death update. But please do not run it on your MVC flashed cards. Our magic is in the EFI and it is doubtful that Nvidia has included a mechanism to maintain Mac EFI during this update.
So don't run theirs. We are busy building new versions of all our roms for this update. And since we have to bust open all the old EFIs, we are going to do another fix.
As some have noticed, our EFI used to flash a tiny text debug window before boot. Then Apple decided to add APFS to 10.13 High Sierra. They enabled booting from APFS by adding it to the Mac Pro 5,1 Bootrom. Unfortunately, their implementation interfered with our card EFI. Nothing catastrophic, but more of a cosmetic issue and what feels like a delay during boot. This text has grown and slowed to a point where it is more distracting now.
The quick and easy fix is to remove all the APFS formatted drives. No more APFS disks, no more APFS text, and no more boot delay. We are going to combine this update with the Nvidia DP 1.3/1.4 update and roll it into future roms. To start, the 1070Ti will be our first new cards, and the first cards shipped with the updated rom.
We will also add GTX1050 and GTX1060 at that time as products, if they have proven stable in the Web driver. As we roll them into existing product lines these roms will also be available to past US customers as an update for a nominal fee and shipping. Please don't start asking, we'll announce when these are available. I am uncertain if our EU folks will be offering past update service or just new cards as they are written.
So, to reiterate, the new EFI will incorporate Nvidia's June 4th 2018 DP 1.3/1.4 update along with a cosmetic fix for Apple's recent APFS additions. The only people who might actually, desperately NEED this update are folks with cMP and and 8K.
As usual, all the hacks, cracks, and other bozos selling pirated versions of our cards will continue offering unpatched older buggy versions, since they can't write their own EFI. If they would like to start licensing our work, now would be a good time to get in touch.
I have had a little disagreement with our Lead Software Engineer. I noticed that all of the other Macs certified for Mojave are 2012 or later. I'm pretty sure they all use the newer "Black" boot screen. I think the fact that the 5,1 has now been grouped with these 2012 and later machines means it should get a black boot screen. We have been testing this, it requires a known hack but looks really cool.
I like it. Lead Software Engineer doesn't. What do you guys think?
