How do you run Octane on Mac? I've searched this question online and have not been able to find anything. I have an iMac with an AMD Radeon card, so I know that I can't use that. Will the new Mac Pro be able to run Octane? It is tricked out with multiple GPU cards etc, but I don't think it is CUDA based. If anyone can help with this question, I would appreciate it - I'd really like to be able to use Octane, but I'm a dedicated Mac user... Is there any information about this online that I can look over?
THANKS

Octane has a build built specifically for the mac. It will run on Mac Pros and Macbook Pros provided that the machine has a native CUDA-capable video-card (from nvidia, specifically with compute model greater than 2.0), the nvidia driver requirements should also be met. The nvidia site has a list of gpus that are cuda-enabled. You might also find more info about Octane and the macs here: http://render.otoy.com/forum/viewforum.php?f=14

I'm on the edge of purchasing the 2013 Mac Pro, but I'm really disappointed they did not offer an NVidia card option 
. I'm buying it for music scoring and video editing. Octane and C4D have been in mind for over a year now. 
If someone knows about the possibility of using a Thunderbolt expansion with a CUDA card, please share the details.

You can build one by yourself but it will look ugly

The best solution is to build a hackintosh with eg. four nvidia gpus for the same price of new Mac Pro.

I went the Hakintosh route before, but I preferred to have the genuine Mac Pro. No more worrying about broken kext drivers. I have already invested in thunderbolt drives, audio interfaces, and docks for my MacBoork Pro. I know the pcie thunderbolt cards work in various solutions, but did not see proof of someone using an external GPU in OSX, especially in the cade of CUDA-based rendering.

Hello
Here is my testimony of my experience with the new Macpro 2013.
I had a MacPro mid 2010 with an Netstore NA255A expansion Box with 3 Titan's in it. Every thing was working great.
On this architecture I thought that I can easily construct the same system with a thunderbolt 2 Sonnet Echo express III-D with my Netstore PPCIe card plug in it to my NA255A. What I didn't know it's Apple put a code line in his system to exclude NVIDIA card to be recognize. What they give explanation that Thunderbolt has to plug and unplug on the fly and Graphic cards can not.
I Can see why we don't have the possibility to use this kind of system under our own responsibility.
So I found on internet a guy who succeed to build this kind of system http://www.journaldulapin.com/2013/08/2 ... ac-how-to/
So is it possible but we have to get one's hands dirty and go to the code.
For now, I tested some but with no result. (I'm not very good in line coded) I ask a help from author of the article and hope he can help me .

PS: If someone has a clue to help me ...

Side question: how has the Netstor been working for you? I've been looking at them recently for my Mac Pro.
It seems the biggest limitation for Thunderbolt connected GPUs is the actual bandwidth Thunderbolt has available. It's fast for things like storage and displays, but PCIe has far more bandwidth. Thunderbolt 2 has a max bandwidth of 20Gbps. One PCIe lane has a max bandwidth of 8Gbps. That means a 16 lane PCIe 3 slot (x16) has a max bandwidth of 128Gbps. This quite a difference. That's not to say its impossible to use graphics cards externally, we've already seen proof of concepts. It's just that Thunderbolt will currently bottleneck performance. It won't affect GPU rendering as much as it will gaming, since the whole scene get transferred to the cards memory, but that transfer will definitely see a speed hit.

For the thunderbolt, I can't say if it's working well or not bcse I can 't test it properly right now, but I can say that In my old Macpro 2010 It Was plug In PCIe 2.0 and I had no issue with Octane an Davinci resolve. The system worked fine.
I can say that the problem right now is more on the limitation Apple did to Nvidia an non the speed of the slots.
