My last render, osx vs win, dual vid cards

[vmedium]

My last render. Thanks to all the help in these forums I finally made something I like
https://twitter.com/vmedium/status/539241033964347392

1) In doing this amazing tutorial I've realized that some things don't seem to be working the same in windows and osx. (tut link: https://vimeo.com/108846254 ) For instance ctrl+middle click to set the focal point, and the white balance in the render settings in the tutorial has a 'pick color from viewer' button that doesn't exist in OSX

2) I have a K5000 in my mac pro desktop right now. I would love to add another card (or more). Is anyone running multiple cards in OSX? and what would a recommended second card be?

Thanks!

2) Decided to go with a GeForce GTX 680 for an additional card for Octane.

This is becoming problematic.

1) They don't use the same driver, still haven't got it running so I dont know if this will be a problem yet.

2) The 680 requires more power than I have available in the PCIe area. (It has two 6-pins wanting a total of 75W from the board and 2 6 pins for another 150W for 225 Total), this means that the K5000 has no power. So I'm going to try it with a Y-Splitter and see how that goes.

i like to help to you, but no experience for osx hardware and quadro. Let's hope that some mac guys contributes to your issue.

No problem Aoktar, I'm only reporting this in case anyone else is curious. Theres little to no info on the nets about it.

From what I know the major issue with octane on Mac (or hackintosh) is that you can only have 3 GTX runing on OSX... I am runing 2 gtx 780ti, and I wonder if I will go on windows or try to make network rendering...

Hi.

OSX supports Several graphic cards. I have 5 (4 gtx 780 and a gtx 580) using a pci extension box. The only pb is with os x 10.9.2 and later. My mac pro Run on 10.9 and it Works very fine.
