I have a well specd Mac Pro trashcan which is i realized is possibly going to take months of continuous rendering to finish an upcoming job in mantra. Cloud rendering will speed things up but it’ll cost a fortune which will come out of my pocket. so I’m deciding what best way forward short term and long term.

Technically I should be able to run redshift on Mac with 2 gtx1080s in 2 seperate thunderbolt connected enclosures. If such a rig actually works it should allow me to render it all locally under Mac OS in a reasonable time frame. But it seems like such a little-used path that worry it’ll end in endless bugs and frustration.

does anyone have experience running redshift on a Mac? I’d appreciate any wisdom from your experience. Thanks.

There's already discussion about that on the RS forum and as far as i know this is working.
May I ask you why on the first place you bought the MacPro trashcan, that's 2013 hardware no ?

Thanks Nnois– i found some productive conversations on redshift forum. Sounds like it will work very well with houdini, redshift and an external GPU. i think i'll pull the trigger.

I've been using the trashcan since it was first introduced. It is a great machine, really. I know that's not a popular opinion but mine's been able to render day and night rock-solid, cool, quiet and pretty fast for over 4 years now without issue. Compared to GPU PC's its like a slow and steady tortoise. With this project though I'm afraid it may finally lose the race unless I finally get with the times.

I would appreciate hearing from others who are running redshift on a mac how their experience is going.

It works fine - as well as the Linux version.

That’s good to hear aryte.

I’ve settled on a 1080ti and sonnet enclosure. If all goes well I may purchase a second one. I’ll post here my experience.

@matleaf – About two weeks into owning an eGPU and my experience has been… awesome! I went with a sonnet eGPU enclosure and a 1080 ti graphics card connected using a thunderbolt 2 to 3 converter. I also purchased a redshift license.

Getting the mac to recognize the GPU was difficult and involved terminal scripts – not plug and play at all (Apple is supposedly fixing this). However once up and running its absolutely smashing through renders.

Many jobs are 20-30x faster. Things like GI and volumetric lighting used to be too time-consuming to consider, I now just shrug. Best purchase I've made in years. Highly recommend. I will buy a second eGPU and card in the coming months to double speeds yet again. Even After Effects now runs faster (I set it to use CUDA in preferences).

Finally, by freeing up the CPU I'm able double the speed of certain tasks. For example I've been able to simulate pyro while simultaneously rendering the previous frame. For example, a frame that takes 4 minutes to simulate and 4 minutes to render will now take a total of 4 minutes to do both by splitting across the CPU's and the GPU, rather than 8 minutes if both were on CPU. Hopefully that makes sense.
