Better to count on Apple killing TB2 for eGPU and being pleasantly surprised if they don't, than the other way around.

Yeah, it makes perfect sense. The eGFX certification only applies to Thunderbolt 3 enclosures, so *officially*, even from Intel (aka, outside of Apple), only Thunderbolt 3 setups can be eGFX supported. TB2 was always a "well, if it works, then have fun with it, but don't look at us if it breaks" type of thing.

Right but even beyond that I won't be surprised if they actively block use of TB3 > TB2 adapters somehow. Not sure about the Final Cut Pro X thing mentioned above — doesn't make much sense that they'd disable eGPU for a piece of software.

Thunderbolt 3 Macs, Sonnet and OWC eGPUs, 4K Displays, etc

Hello everybody,

I'm planning to build the configuration bellow:

- MBP retina mid-2015 (MacBookPro 11,5)  with internal dGPU AMD Radeon R9 M370X + Intel Iris Pro

- Apple Thunderbolt 2 - 3 Adapter

- Razer Core v2

- GTX 1070ti

What's the current behaviour in MacOS high Sierra last current build (10.13.2 17C88)?

 

Cheers eGPU enthusiast !

Old hardware: MacBookPro11,5 (15 Retina, i7 4980HQ) dGPU R9 M370X + TB2/TB3 adapter + Razer Core v2 + GTX 1070 Ti

New hardware: Mac mini (2018, i7 8700B, 32 GB RAM, 1 TB SSD)+ Razer Core v2 eGPU + SAPPHIRE Radeon RX Vega 64 + Samsung C27HG70 display
New software: macOS 10.14.2 (18C54), Windows 10 to be tried !

Hi,

just wanted to let you know that my eGPU build with a Sonnet eGFX Breakaway Box 350 and a Sapphire Nitro+ Radeon RX580 connected with Apple Thunderbolt 2 – 3 Adapter to a MacBook Pro (Retina 13" late 2014) and an  iMac (Retina 5K, 27-inch, Late 2014) worked out of the box using macOS High Sierra Version 10.13.2 (17C88).

On the other hand my first attempt with the same hard- and software but different eGPU enclosure (HP Omen Accelerator) didn't work.

The Omen never turned on.

Ordered an Akitio Node and an RX 580. Wish I read this sooner. Can’t use it in 10.13.2 at all.

I am curious to know, does anyone have a clue, why some eGPU systems with the tb2tb3 adapter work under macOS Sierra 10.13.2 and some don't?

Assuming that the tb2tb3 adapter from Apple hasn't changed, or has it?

Isn't the TI83 USB-C controller the same on all enclosures or does it depend on the specific mac model or the cables?

nMac Pro (late 2013) 6,1 with Akitio Thunder3 with Titan Xp using TB2>TB3 adapter. It was working great with OSX 10.13.1. I was getting VRay render times that were 2x faster than the POS D700s. Made the mistake of "upgrading" to 10.13.2, had to update drivers/enablers, etc. Now, the eGPU and Titan show up properly, but render times are slower than molasses. Render times are ~4x SLOWER than the D700s.

I doubt there's a real reason for this other than greed.

Just updated to 10.13.3 b3 on the 2015 MBP15 2.8GHz TB2 and it still crashes badly. However over in bootcamp on Win10 the AMD RX 580 in the Sonnet box is working an absolute charm on the same TB2 laptop. 

There were new AMD driver versions on b3. Still no joy for me though as a mac.

There's no problem on my TB3 mac though. It's just the TB2 one that's having issues ATM.

In addition to my previous message, I received my eGPU box (Razer Core v2) and it works out of the box with my MacBook Pro retina (mid-2015) and a Thunderbolt 2 - 3 adapter.

I’m using last build (no dev or public beta) of High Sierra.

I've noticed more issues with 10.13.3 too. While the eGPU still connects and shows up in System Information with my nMP, there are more visual glitches. Maybe it has to do with the RX Vega 56 I'm using. I sincerely hope Apple doesn't actively exclude older Thunderbolt Macs from being able to use eGPU.

As a test, I gave it a shot with my 2017 Macbook Pro. Same results with slow renders in VRay. So, maybe it's not a TB2/3 issue but is, instead, a VRay/CUDA driver (387.99) issue since that was updated in the process.  🙁
