I did that to but the response I received from Apple advisor is that Apple does not support eGPU. You need to contact the manufacturer. Seems like there are some dumb advisor in Apple support. The advisor was asking me how are you trying to connect you eGPU to your Macbook Pro through wifi or through bluetooth?

There is no way an Apple tech support person would ask you if you connected through wifi or bluetooth. Perhaps you were reading the Apple Support forums (which are not answered by Apple employees but by random volunteers)? If so maybe provide a link. Surprised you would get such false information there, especially after the official launch, which every support person inside Apple is going to know about.

I'm still on 10.13.3 with an Early 2015 13" MBP and Breakaway Box/RX 580 combo.  Kind of a dick move for Apple to be dropping TB2 support when they don't even make a headless TB3 computer yet or anything professionals actually want... no new MacMini, no MacPro... hell, not even a quad-core 13" yet.. just more iPads and iPhones and emoji engines. What a joke.

purge_nvda.sh and purge-wrangler.sh worked like a charm on 10.13.4 🙂 Awesome work!

Original post should be updated with screenshots for TB3 Macs with the eject button showing the eGPU name.

Anyone know why the connected and recognized eGPU isn't being used? This is the same in both clamshell and open modes. The system defaults to the Pro 460 instead of the eGPU RX480. 

I disabled auto graphics switching as well and same both ways. 

Thanks in advance!

@shootmcgavin Not 100% as I only use mine for compute power, not screen acceleration, but the external monitor has to be connected to the eGPU I think?

Hey Phil,

From what I've read over the past few weeks, you're in the exact same situation as what I'm looking to do!

I'm having a complete brain freeze trying to take in all the developments over the past year - basically, all I'm looking to do is use Octane and Redshift on my home set-up.

I use Octane at work on my 2010 Mac Pro loaded with 1080ti cards, but want to start roughing things out at home due to needing to spend more time with my newborn.

What I want to do is connect a 1080ti to a 2017 TB3 MacBook Pro and use it for compute power in MacOS.  Not bothered about screen acceleration or gaming... Annoyingly I don't have the space for an external monitor at home, does this mean I need to get a headless/ghost HDMI, or can I set Octane to see and use the card once the nVidia drivers are installed, without the OS using them to drive a display?

 

Don't worry, not looking for a guide - pretty comfortable with what I need to do in general - just trying to decipher if things are different for compute users or I need the monitor or ghost HDMI for compute power.

 

Thanks for your help, and sorry if this has been explicitly answered before - there's so much to dig through and it mainly seems aimed at MacOS gamers and FCP users...

@lovejimbo You'll see my trials and tribulations here:  https://egpu.io/forums/mac-setup/script-enable-egpu-on-tb1-2-macs-on-macos-10-13-4/paged/6/

Basically, I'm now successfully running Redshift and Octane on my TB2 iMac 🙂

I had the extra step of fixing the dropped support for TB2 so you are natively TB3 eGPU (for AMD cards) if running 10.13.4.

Getting Nvidia running is a bit "manual" and sometimes scary...

Best step by step is@rhenriques11 's post about half way down. Obviously, not being as fancy pants as you on TB3 your mileage may vary!

I don't have a screen hooked up to the eGPU, but I do to the iMac itself - not sure if that makes a difference.

Perfect, cheers Phil!

Don't suppose you've had much hands on with C4d Prorender with AMD cards? If so - do you feel it's production ready, or is Octane the way to stay?

Thanks for your time 😀

Jim

Not loving Pro-render so far Jim, but not really had time to test it in anger. I think even by Maxon's own admission it's not quite ready. Looking forward to Octane 4 C4D plugin, and trying my best to master Redshift between earning a living and sleep... Do you own any Greyscalegorilla plugins? If you do you can join their Slack channel - where I find out loads of stuff...

Gotcha, thats one thing I haven't tried because I was hoping to keep everything USB C/TB3.

There is no output for USB C on the Akitio Node, but I can try a Displayport option out of the video card.

Update: It works! Unfortunately on Display Port only, not USB C. Which is a shame because my PC was using display port input

On the just released HS 10.3.4 I've notice that, although hot-plug works better that previous betas, when I open FCPX after hot-plug my eGPU I have some sort of display artefacts and often FCPX crash at open but after a log-out & a log-in to the system everything came to normal. So I think they have to work a little bit better on that side.

Since I have 3 GPUs (integrated, Pro RD 460, and the eGPU RX480) would it best to run one monitor on per GPU for best results?

USB C from Pro 460 first monitor 
DisplayPort from eGPU for the second monitor. 

Or is the OS able to merge the processing power of all of them?

I would connect everything  to the eGPU. OpenCL and Metal performance can be comulative of all GPUs

eGPU.it | LG 34" 4K 34UC88 curved ultrawide display
MacBook Pro 2018 Touch Bar i7 quad-core 2.7Ghz - 16GB RAM - 512GB PCIe SSD --> my Mantiz Venus extreme mod with Sapphire Nitro+ RX Vega 64

Anyone knows something for the Aorus Gaming Box 1070? Have tried some of the forum solutions and I am on 10.13.14, but to no avail does it get detected.

After about 3 months I can say either my eGPU RX480 isn't doing anything or my software isn't taking advantage of it.

Some notes
Photoshop CC runs the same, actually think it runs better on on the onboard RX460 on the MBPro Touch Bar. 
Capture One runs the same (OpenCL enabled)
The RX480 fan doesn't turn on after start up. Not sure if its temperature controlled? 

Any thoughts? When I benchmarked it on Geekbench, performance on the RX480 was 4x the RX460. Just not seeing any performance improvements anywhere. 

Does Final Cut Pro utilize eGPUs better?
