Kudos: This build would not have been possible without @itsage.

System Specifications

  • MacBook Pro 15" (2018)
  • CPU: 2.6 GHz Intel Core i7 (i7-8850H)
  • GPU(s): Intel UHD 630, Radeon Pro 560X
  • macOS 10.14

 

eGPU Specifications

  • Sonnet Breakaway eGFX 350W -> 600W Corsair Upgraded
  • Sapphire R9 Fury Nitro
    Note: 
    Card is a tight fit.
  • Apple TB3 Cable

 

Installation

The installation process is usually straightforward if you use one of the solutions on this forum.

For macOS

  • Use purge-wrangler.sh (Option #1).
    v4.2.1 or later required.
  • When asked, choose to enable legacy GPUs.

 

No need to restart the system. eGPU should be immediately functional.

Not all applications take advantage of external GPUs. For that, one can use set-eGPU.sh for High Sierra (10.13.4+) or use the Prefer External GPU option in Mojave.

 

Benchmarks

Some interesting benchmarks:

LuxMark, W/O eGPU

LuxMark, W/ eGPU

Valley, RP560X, Internal Display

Valley, R9 Fury, Internal Display

Note: The GTX 780 performed significantly better than the R9 Fury in macOS in Unigine benches. Some interesting stuff going on with Apple's drivers.

 

Comments

I only use the eGPU for testing purposes at this time, but my experience and benchmarks make the following clear:

  • Compute performance over 560X: ~3x.
  • R9 Fury is not optimized to the fullest on macOS, as evident with meagre gains in Valley.

Hi buddy,

i have a general question. I thought the R9 is natively supported. Why do you still need to run purge wrangler?

Hello Vindiesel and mac_editor. I am curious if you could help me out or point me to something / someone that could.

I am trying to get my eGPU to work.

I am seeking help getting my setup working on my iMac and my MacBook Pro.

 

My Hardware:

eGPU Enclosure: Sonnet eGFX Breakaway Box

GPU: EVGA 1080 TI Founders Edition

OS: macOS Mojave 10.14

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

@vinhdiesel Apologies for not responding to this. Script needed because R9 is not natively supported.

@brendan_collins wait for Web Drivers.

There is no way to use an older web driver?

@Brendan_collins what is exactly not working? Can you specify what hardware and macbook you are using?

@mac_editor, I am trying at this moment an vintage Radeon HD 5850 with High Sierra, but I have no success, even with purge-wrangler. Can you tell me, what I am missing? Is it doable at all?

The legacy AMD eGPU support may not have included the HD 5850. Here's the note provided to me by @goalque.

I see. Of course, the performance is not that great, so nobody will use it as eGPU productively, only for testing purposes 🙂

@itsage, @mac_editor: One thing I do not understand: ATI Radeon HD 5850 has been the official GPU in Late 2009 iMAC (Model MB953xx/A)
Why is it wrong to except this to be supported in MacOSX natively?
