There are now new drivers for OS X 10.10.5 and 10.11.6 available on our Drivers page. They resolve the issues created by the OS X security update from two days ago.

Well, haven't got any emails about this yet but be aware that if you have any of the "Must Have Web Driver" cards (780Ti/Titan Black/750/980/980Ti/Titan-X) that you should NOT run this update yet.

Nvidia will doubtlessley have an update in next day or two. So, most folks should just be patient and all will be well.

For those who clicked before thinking and now don't have a working GPU going backwards isn't easy.

With a few terminal commands you can be back up running.

1. Go to S/L/E and drag "NVDAStartupWeb.kext" onto the desktop. Do it again. OSX will warn you that there is already one on desktop. Hit "Keep both" This should result on one with right name and one named with the number "2" after it. The one with "2" is your backup in case things go south.

2. Right click to get inside, use X-Code or a text editor to open the info.plist. Drill down to NVDARequiredOS. Where it shows "15G31" change this to just "15G"

3. Save and close.

4. Use a kext utility to install this into S/L/E.

5. Boot into recovery partition. This can be tricky, even with an EFI Maxwell card. Have a look for the nv_disable=1 trick, it will allow any EFI card to get there.

6. Open the terminal here and type "csrutil disable". You will need an admin password.

7. Change boot args to remove nv_disable.

7. Reboot, all should be well.

​Please note, these instructions assume a fairly high level of knowledge. If you don't understand this stuff, just wait a few days for the fix.

UPDATE: Best option is to roll back to "BETA" versions of these drivers. Look on our Driver Page. Find your OS (ie, 10.11.5 or 10.11.6) and look for FIRST driver in list. Easy way to tell Beta from Final is the letter "b" in the name versus "f". (Captain Obvious reported this)

UPDATE #2: Nvidia has kindly released drivers for 10.10.5 and 10.11.6, linked on our driver page. The 10.11.5 driver is corrupt so those folks should keep using Beta driver until it gets fixed.

We have heard from several folks with issues using Adobe applications with latest OSX release.

Adobe has identified the issue and there is a temporary fix.

Loks like between Apple, Nvidia, and Adobe somebody dropped the (metal) ball.

Note that this has nothing to do with MacVidCards or our EFI roms or cards. The issue also occurs on EVGA GTX680 Mac Edition cards and GT750 cards in Macbooks.

​Will update when a better fix is out.

UPDATE: New Nvidia Web Driver on our driver page.Can someone report if this fixes and allows Metal to be used?

So our Customer Service and orders have been slightly erratic recently. We have encountered family issues which will hopefully be resolved shortly. Apologies in advance if you feel neglected, we will fulfill all orders and answer all emails, maybe just not as quickly as usual.

​Thanks for your patience.

As I recently posted on Netkas, OSX Sierra has drivers for the AMD Fury Nano. But oddly, if you put one in a cMP, it is useless. 

I was only able to get it working on nMP 6,1 via an eGPU.

The "little trick" is that you have to add the device id of "7300" to the Baffin personality. For those  not in the know, Baffin is a new Polaris chip.

Sooner or later we will figure out what the "missing piece" is to get this working on cMP. Probably just a little tweak here or there. If we could do that, then maybe we consider an EFI rom and taking the time to find PCIE 2.0 resistor.

Before anyone gets TOO excited consider that for both 6970 and R9 290X/390X Apple gave, and tooketh away. Driver support was good, then broke in later iterations. But fun trying anyway.

I dragged the Rift setup into the Lab where the cMPs are. Hooked it up to a 4,1/5,1 with a 3.46 6-Core and a Titan-X.

To make sure it would work well, I also used an Inatek USB 3 card. 

Setup was even easier than 6,1 nMP. 

On the plus side, it ran perfectly. On the "minus" side, it kept remid=nding me that my hardware wasn't good enough. I think it meant the built in USB 2 or the Westmere CPU.

But it ran just fine.

The game Chronos was smooth and efficient, looked good and ran smoothly.

​I may try with just the USB 2 and see what it does. But it is proven, there are Macs that can run VR. They just need a little help.

The Rift finally arrived and I got it all set up last night.

Pretty cool. Hooked it to a nMP 6,1 12 Core and an eGPU GTX1080. Smooth as silk!

Will be trying on a cMP 12 Core soon. I will also use a USB 3 card with that, but try with USB 2.

Nice to see that there are 1 or 2 Macs that are up to the challenge. Tonight I will download "Valkyrie" and try that.

Does anyone know of a good VR benchmark?

I realize it's kind of tough to do, but there must be a way to comnpare, beyond the subjective.

On another note, the "Catatonic" VR movie creeped me out. Definitely more scary than watching a movie on a TV. Turning around to see who was pushing me and discovering that the orderly was gone, and a psycho had replaced him was something. Also enjoyed the demo with the T-Rex attacking.

UPDATE; After several days of testing I can report that it is quite stable and solid on 6,1 nMP.

We had someone ask about the DP to HDMI 2.0 adapter and I was skeptical. So I got one.

And IT DOES WORK WITH MACS BEAUTIFULLY !

Even on a underpowered DP port from a 2014 Mini I was able to output 4K 60Hz HDMI to a 4K TV with HDMI 2.0 input.

​No drivers, no settings, no nothing. Just plug it in and enjoy the 4K experience.

The one I got was from Micro Sata and was $30-40. There is also a hack I have been made aware of to enable higher pixel clocks, haven't tried that yet.

The fact that a simple adapter can produce these signals tells me that Apple has deliberately crippled certain setups and thus it is likely that the hack also works, or could.

Anyhow, I was even more amazed when I went to try the adapter on a MacBook Air. I was copying things to a TB drive and realized that the Air only had 1 @ TB/MDP port. But my Akitio chassis had a TB Daisy Chain port. I plugged it in there and had 4K 60Hz HDMI ! (While Restoring a PCIE SSD at same time)

Nice little product, might grab a couple dozen and stock them.

Turns out Sierra works even better with eGPU than did El Cap.

With EFI eGPU on nMP complete functionality, no system hacks needed.

Just wanted everyone with a 4,1 or 5,1 to know that we have slipped under the knife one more time.

The 3,1 will require a few tricks to work with Sierra but so far the 4,1/5,1 are easy breezy.

Hopefully they don't titghten things down in the final GM.

In other good news, Nvidia has already released a Web Driver for 10.12 (see our drivers page) and it has HINTS of Pascal support. So I'd say it's a fair bet that we will be seeing GTX1080 and GTX1070 running on cMP soon.

​Hats off to Nvidia for standing by us as Apple continues trying to become a toy company.
