System Specifications

  •    Model: MacBook Pro 11.3 (Retina, 15-inch, Late 2013)
  •    Processor: 2.6 GHz Intel Core i7 ( i7-4960HQ )
  •    GPU(s): Intel Iris Pro 5200, NVIDIA GeForce GT750M 
  •    OS: macOS 10.13.6


eGPU Specifications

  •    Enclousure: Sonnet Breakaway eGFX 350w
  •    GPU: Asus ROG Strix Radeon RX 580 8GB ( fits in fairly easily )
  •    Cable: Apple Thunderbolt Cable, Apple TB3 -> TB2 
  •    Display: Dell U2515H Display - via DisplayPort
  •    Display: Samsung 40” HD TV - via HDMI through Pioneer VSX-831 - works no different then being plugged in to HDMI on the macbook



   1. Install RX580 in Sonnet breakaway 350w
   2. Connect external displays to RX580
   3. Run purge-wrangler.sh: to enable using an eGPU with TB2 on macOS 10.13.6
   4. Plug eGPU in to the MacBook: external monitor connected to the eGPU displays a black screen and the OS gets really slow
   5. Run purge-nvda.sh: to disable that pesky discrete GPU (NVIDIA GeForce GT 750M) : in order to not generate conflict between the GT 750M and RX580 (This failed and wasn’t able to boot. had to recover. )
   6. Deleted all the Nvidia drivers I had installed.
   7. Run purge-nvda.sh: worked this time!

Persistent issues

  •    I’m unable to change the internal displays brightness. Is this a know issue? 
  •    GT750 still seems to be using power despite being disabled. Not sure if this is a know issue?
  •    Sometimes system process are using the eGPU and I have to force disconnect or quit the process to disconnect the eGPU.


   On external Display: Unigine Valley
   On Internal Display: Unigine Valley

   Will update with more in the future.


   Just testing out at this point, hoping to speed up my photo and video editing process.

how did this go?

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