CUDA and Mojave Mac 10.14

[alphaae]

Well here we are again with Apple and Nvidia not working together.

I use CUDA fairly regularly for encoding my videos in Adobe products and it's great to get that extra horse power from the GPU.

Unfortunately with the new OSX there are no drivers or support for older GPU on the Mac.

I no longer have access to CUDA as a rendering option.

I've also attempted to download and use the NVIDIA Driver manger to enable CUDA on my Mac and it's not supported.

I contacted Nvidia and they have no plans or information about their driver being supported. When talking with the rep they indicated that only Apple provides the drivers for the device. However this is not true as I have been using driver directly from Nvidia with OS 10.13.

Just thought I'd throw this out there for people who are wondering why it's not working and hopefully someone else and drivers soon.

I will keep talking with Apple and Nvidia to see how this can get resolved quickly for those of us who use this feature.

No Fermi or earlier GPU's are supported from 13.x on ... which means you have to have a 900 series or newer GPU of the GTX types, and also means many older Quadro cards are no longer supported also.

So ... which GPU do you have?

I have a Mid 2014 MacBook Pro with the 2GB Geforce GT 750M.

To answer a few questions.

I have installed a CUDA driver of some kind on my device here's a pic.

This is previously the same thing I was using when I had CUDA working prior to the 10.14 update. These drivers were provided by Nvidia and not Apple. When I was trying to get CUDA working about a year ago this was the the process I used as Apple did not provide the necessary drivers and tool for me to take advantage or CUDA and Adobe Products together.

Neil when you said it would not longer be supported after 10.14 who is indicating that? Apple, Nvidia, or Adobe?

The reason I ask is depending on who indicated it would not work may be the point were I give up hope of using this wonderful feature anymore. If it's Apple I can still hope that Nvidia and Adobe work together and can push an update outside of Apple's control as I previously have done. If it's Adobe or Nvidia then that's the end of the discussion as they will not be working to support it at all.

I'd have to say I'd be pretty disappointed if either Nvidia or Adobe indicated they were done updating. I have a feeling I wouldn't be the only one who has a similar or older Mac set up. Also after checking last night Nvidia has an update for the Geforce GT 750M on their website for Windows 10 that was released less than a month ago. Why would they not support this older card for Mac? Same thing for Adobe I pay for the creative cloud service monthly why will you no longer support a piece of hardware that makes your product better?

Just my two cents but thanks for the replies.

Ah, I see the confusion. CUDA is not the GPU driver, it's the platform for hardware acceleration. On Windows this is bundled in the same package as the actual display driver, but it's separate on the Mac because Apple controls the display drivers.

Here's an official response from Nvidia: https://devtalk.nvidia.com/default/topic/1042279/cuda-setup-and-installation/cuda-10-and-macos-10-14...

There is a newer version of CUDA, but you can't get it because you don't have the latest display driver, which Apple hasn't created. Hopefully they'll get to this because there are plenty of powerful computers out there with Nvidia cards in them, but again, only Apple can officially fix this.

David you are a gentlemen and a scholar.

Well I'm glad to hear that there is still hope that we can leverage CUDA as a tool to increase the performance of adobe products.

I guess I should have waited to upgrade to Mojave.

Not sure if the mods want to close this or not until we receive a response from Apple about allowing an upgrade.

[David Arbor]

No need to close the thread, we don't really do that on this forum.

One more note, stick with Metal over OpenCL. Adobe has worked very hard to make Metal nice and performant (yup, totally a real word, even though it sounds ridiculous) in PR and AE, and ideally you should be seeing the same performance gains with Metal as you would with CUDA. The major downside to this issue right now is that it greatly affects apps that require CUDA, like GPU renderers for 3D apps.

As Neil said, which GPU are you using? If you have a Mac straight from Apple, even one you customized, then yes, Apple provides the drivers. If you have a eGPU, cheese grater Mac Pro, or Hackintosh, then you would get drivers directly from Nvidia.
