Is anyone running macOS 10.12.3 and not having any issues with their Mac Pro + eGPU setup? Just want to check before I update.

Sooooo..... Finally got some success with eGPU and FCPX 10.3.2.  Had to use a Displayport to HDMI 4k 60hz adapter.  Found it on Amazon.   Came straight from Titan Z to my 4k display.  Thankfully I am only using a single monitor.  If I plug in a HDMI to the Titan or the Mac Pro to get a second monitor in directly and launch FCPX, it crashes again.  

Also I am still only able to get a single Titan Z or 980ti to boot in Sierra 10.12.2.  However it is nice to have FCPX and Octane working without having to restart constantly.  thanks all for the help.

For those interested, I have posted the build of my eGPUs over on my Instagram

Quick question: have you tried daisy-chaining the two eGPUs (assuming your Akitio cards have two thunderbolt ports)?

I have a build very similar using a 980Ti with the cards from a HighPoint RocketStor 6361A in a Silverstone SG13B case. 

I've been debating adding a 2nd identical setup for the Octane/Cycles speed gains (and hopefully DaVinci Resolve also). Which got me wondering:

There's a lot of empty space in these cases, and SFX-L power supplies exist up to 800W which would comfortably drive both 980Ti cards. 

If the two Thunderbolt cards work daisy-chained, I'm trying to figure out if the entire two-card setup could be fitted in one (perhaps custom) case with a short internal cable connecting them?

(Or if anyone who knows more than I do could chime in, is there any kind of daughter card or riser that could put two GPUs on one thunderbolt controller card?)

Thanks

PCIe switch-capable risers exist. They can be used to connect two PCIe devices to a single physical slot by switching PCIe traffic between the two devices, each in their own downstream slot. They do not tend to be cheap, though (except of single-lane ones that can be found for relatively cheap on ebay).

Give your Node Pro a second Thunderbolt3 controller for reliable peripherals by re-using a TB3 dock (~50$).

Good to know there are other options... it's quite expensive and would that power supply be adequate?
