So I finally got some time to experiment with macOS High Sierra and see how things pan out. I am currently away from home so I don't have all my stuff, but the setup is as follows:

Does it work? In a nutshell, not exactly.

What happens - 

  • Boot into High Sierra Beta 2.
  • Connects eGPU TB cable.
  • eGPU detected and logout requested.
  • On logout, external screen lights up, but is completely messed up and glitchy.

Since detection was fine, I think it is a matter of fine-tuning, probably, and that it may be resolved in further betas. I am trying out of a few other things at the moment. Of course, this setup works quite well on macOS 10.12.5. Any suggestions would be appreciated.


I tried booting with the eGPU connected. For a moment, I saw the glitch on the external display, then the mouse cursor, and then everything stayed black. No luck yet.


For reference, some pictures:

not  surprising, in my opinion there a problems with the dGPU from Nvidia, all other users owning a MBP with Nvidia dGPU have the same issues...

i really hope apple is going to fix this, we definitely should push them to do so. otherwise we have to figure out how to completely deactivate the Nvidia dGPU

MacBook Pro Retina 2013

Apple Thunderbolt 2 to Thunderbolt 3 Adapter

Akitio Node w/ Sapphire Radeon NITRO+ RX 580 8GB

RX 580HDMI connection to monitor

 

Works fine in Sierra

High Sierra not so much. Node monitor is alternating columns of colored lines.

 

Retina screen is black.

Fingers crossed that this is an early beta issue ...

rMBP 15 with NVIDIA GeForce GT 750M

I believe rMBP 2012-2015 have an NVIDIA discrete processor
and 2016 & 2017 changed to AMD.

Is the Apple response shared by Mac_Editor above a statement that
all rMBP that have an NVIDIA processor
will be excluded from running High Sierra with an eGPU once High Sierra is finalized?

I've reported the issue in my beta reports and I hope everyone affected reports it.

More than a hand full of people bought those models!
I'll keep hope alive that the final release will not have that baggage.

@cantonvi: Late-2013 upto Mid-2015 15" retina MBPs had integrated-only models available.

According to Apple, external graphics on Thunderbolt 2 is an unsupported configuration. This means that they are not working on making High Sierra compatible with TB2 devices. That being said, they are not blocking these notebooks either. Therefore, their response is not really disputable, although disappointing. We are only at beta 2 at the time of writing, and many more changes are to come in subsequent betas that might change the situation with these notebooks. Note that officially stable compatibility for external graphics is slated for Spring 2018, so there probably is tons of work left on Apple's part. We will have to wait and hope - or just upgrade already to a TB3 notebook.

Can you give more info on your Macbook pro.  You do not say what size, 13 or 15 and is it early or lat 2013? 

 

I ask because I have my late 2013 retina 13in MBP running the apple Dev kit perfectly fine on High Sierra using TB3 to TB2 adapter.  Also have it working perfectly on my 2012 macmini with the TB3-TB2 adapter.  Only two differences are that I am using the breakaway box and I am not using hdmi but display port.

MacBook Pro (Retina, 15-inch, Late 2013)

2.6 GHz Intel Core i7 • 16 GB 1600 MHz DDR3 • NVIDIA GeForce GT 750M 2 GB • Intel Iris Pro 1536 MB

I use Final Cut Pro X and dabble in 4K, which makes the egpu work - and saves me a lot of time that I would otherwise be waiting on rendering / gpu intensive tasks!

I am running High Sierra on an external SSD for now
until the High Sierra beta or release can use the eGPU with the rMBP 15 inch 2013

Even when I upgrade to a newer laptop, I hope to continue using this one with FCP so I can concurrently work on different projects or have it available when I am jointly working with another editor/videographer.

No changes on macOS High Sierra Beta 3, except for a different color glitchy screen.

Just confirming that the RX 480 4GB edition works in High Sierra Beta 4 using Late 2013 MBP 13" and Mid 2012 MBP 13"

Also, I might have discovered a method to get things going with High Sierra + 750m Macs. I'm testing more stuff out. Stay tuned!

We’re looking forward to seeing your workaround on the 750M Macs. Thank you!
