GTX970 and Mojave

[norda72]

I have Nvidia Geforce GTX970 4 GB in my Mac Pro Quadcore mid 2012. It’s a flashed PC-card which gives me trouble with high spinning fans at start up, black fields in file lists and lagging I bought it to get better compatibility with my 4K-screen, HP Z27s, and to be able to upgrade to Mojave. But will Mojave work with these issues? The card has support for Metal, but I don’t know what version. I have latest Cuda and Nvidia Web-driver, it doesn’t work anyway.
The seller on eBay promised that everything should work perfectly and all my wishes would come true. He had never heard about any problems with the flashed cards, until I complained. I have been talking to other sellers on eBay and some say that the card is badly flashed with something called Mac Edition. I have lost much money because of this, and now I’m not sure how to deal with this. Buy another card will probably be necessary. I guess that Mojave will be the last upgrade for this Mac Pro. In a year or two it will be obsolete and it’s just to buy a new machine for 5 000 $...

The only reputable Nvidia card modifier that I am aware of is MacVidCards (MVC). Their cards work in Mojave. The do have a representative in Europe.

The fan issue can't be resolved. The issue is your card was designed with PC BIOS/UEFI in mind. It can't communicate properly with the Mac Pro's SMC, even if flashed by a third party.

The graphics corruptions are because the drivers are not native to the card. These are beta drivers (no matter what salesmen on various forums tell you) and officially Maxwell or Pascal support has never exited the beta phase. From what I have read on Hackintosh forums, even things like iBooks don't display properly with these beta drivers.

From what I have read, MVC flashed cards do in fact work in Mojave. I have no first hand experience however, BECAUSE NVIDIA HAS NOT RELEASED DRIVERS FOR MOJAVE, but they will when Mojave reaches final release.

Regardless if a card is flashed or not the beta quality drivers and visual glitches will still be the sticking issue. Now that Apple supports egpu Nvidia has no excuse not to develop the drivers.

So there are no real drivers? Not even on Nvidia’s homepage? So if I should buy a card from MacVid Cards, the result would be the same? I have dealed with graphic cards in 2,5 years now, but it seems like I must give up. I have no money for new Mac. Buy a PC? I am not sure. Windows is so different from MacOS, but it’s probably better. MacOS doesn’t even support HDMI 2.0, just 1.4. That really sucks! Would a change of screen be good? Dell maybe?

Indeed. The drivers are officially for 6 series. They enabled 9 and 10 series only as a beta. It won’t make a difference if you use a flashed card or not as that has nothing to do with the bugs you rxperi nice in the operating system. The flash from macvidcards is only for a boot screen if anyone wants that.

^^^^Whether the Web Drivers are Beta or not seems up for debate. I believe they are final release by Nvidia on the cMP. But, Beta on other Macs as stated on their website - see attached. Others have a different opinion. In any case I have not yet updated to Mojave because Nvidia has not released Web Drivers yet. When they do I will hop aboard.

As far as a boot screen, in the current environment with the FW updates, the Boot screen has become more important. I, personally, am running an MVC Gigabyte Gaming G1 GTX 1080. It's my third MVC card. They all have been trouble free for me.

They have remained in beta and never finalised Maxwell and Pascal support for any version of macOS. Guys on the Mac Pro forum, egpu.io and Hackintosh websites have all confirmed this with Nvidia tech support. Very very surprised you don’t know this as an active member of Mac Pro forum unless you are a partner with macvidcards.

It didn’t even make sense today ‘finalised for cMP’. Th drivers only see the OS version, not the type of Mac. The only reason the machine is mentioned in ththe support article is because those cards we’re not being used in any other type of Mac. The article was first written before egpu was a thing.

^^^^Please stop playing that same old record. You SAY they are Beta the image I posted above from Nvidia's website SAYS they are not. Be surprised all you want, but you are dead WRONG!

Question, why do you take up space by requoting every post you are responding to even if yours is right beneath it??????

We have been told by Nvidia support that they are beta for Maxwell and Pascal.

The tech support article makes no mention of anything beyond Kepler.

Sorry, sounds like you’re trying to sell flashed cards on the forum. Hope not. That OP has mentioned he has financial strain and cannot afford to waste more money. He should save the money towards a new machine with official supported peripherals.

^^^^Please CEASE and DESIST spreading BS about me. I have also talked to Nvidia support and got a different answer that, again, coincides with what is PUBLISHED on their website. Maybe you have trouble with reading and comprehension.

In any event, when a non-supported (by Apple) Nvidia card is installed in a cMP - Mojave does NOT have Nvidia prepared web drivers yet. And, again, I have not updated to Mojave because of this.

And again, from all I have read in these forums, you really have no experience with any of this. I do!

BTW, this was posted by Nvidia in April of 2017:

you could try using Mac fan control and yes I read there will be a release of web drivers for Nvidia as soon as the final release of macOS Mojave is issued in September Tim macvidcards

Mojave is still in BETA and the latest Nvidia drivers do not yet work with it. I too just purchased a Mac EFI flashed GTX 980 Ti 6144MB card from Macvidcards.com for my Mac Pro Mid-2010 and it worked well in High Sierra and it did allow me to install Mojave (I could not previously) but I am not getting any acceleration from it and Mojave is not enabling the Nvidia driver. Seeing graphical artifacts and other glitches. Mojave is using a generic video driver because the High Sierra Nvidia driver is using OpenGL drivers, not Metal2 drivers.

The Mac Vid Cards website lists links to the drivers for OS build release versions and Mojave is not yet an option. This means you have to either downgrade to High Sierra if you require GPU performance and wait for Mojave support to come from Nvidia or live with it until Nvidia publishes a new driver. I am sure Nvidia will deliver, they might have an ALPHA Metal2 driver in the works and perhaps some private BETA tests going on right now. But unless you have some insider access to Nvidia you aren't going to find a driver to work till they release it.

Bottom line: Mojave is not yet a production release and as such problems such as this will occur. Nvidia doesn't have to support it till Mojave ships but that doesn't mean they won't be late shipping a driver. All we can do is be patient and wait. If you have work to get done, restore your system from High Sierra backup. You did a backup prior to installing a BETA operating system? I hope so. Otherwise, you will need to extract your data to an external drive manually and then wipe out the OS and start over with High Sierra.

Apple looks to release macOS Mojave on 9/24 so two more days. But will Nvidia release their drivers at the same time? That remains to be seen. Hope so... Things run but very slowly without the Nvidia drivers.

^^^^My experience is that Nvidia will release it's Web Driver within 24 hours, sometimes even sooner, of the final release of a MacOS.
