Need help with 2014 MacBook Retina using Bootcamp - connecting to an NVIDIA 1060 in a Razer Chroma
- MacBook 2014 15" Retina
- Intel Core i7-4770HQ @2.20 GHZ
- 16 GB RAM
- Intel Iris GPU
- Windows 10 Pro 2004
- MacOS Big Sur
- NVIDIA 1060
- Razer Chroma
- Apple TB2-TB3
- Apple TB2 Cable
Steps Taken so far
- Method 1: MacBook booted into Windows. Hotplugged into TB2 outlet. GPU not detected
- Method 2: MacBook restarted into Windows, GPU plugged in as soon as Windows logo appears and the circle starts forming (multiple attempts). GPU not detected
- Method 3: Booted into Mac OS, installed purge wrangler, installed AMD GPU (I know I don't have an AMD card, but this was to try and enable TB2). Restarted with Windows and hotplugged GPI at the start. GPU not detected
I can see the GPU come on (I can see the lights) but the Graphics adapter stubbornly keeps showing up only the Intel Iris. The card works fine on a different 2019 MacBook Air with TB3 ports.
Possible Workarounds that I have not tried
- automate-eGPU EFI - I am not even sure what this actually does
- Downgrade from Big Sur to High Sierra (not sure how I would do that even or if it would help in Bootcamp)
what else should I try? What am I missing? Is there any other way to make Windows recognise the TB2 port? I have not been able to find a build or set up quite like mine in the Build section.
@antimony, Do you see the eGPU enclosure in macOS under System Information > Thunderbolt?
@antimony, That's good the Thunderbolt connection is active and it's not a hardware issue. Older Macs don't have good hot-plug support of Thunderbolt devices so you may want to use cold-plug (eGPU connected prior to booting into Windows). EFI boot loader such as automate-egpu helps this cold-plug process by keeping the iGPU activated. Otherwise, the MacBook Pro internal display would be black due to disabled iGPU.
@itsage, I cannot see it on the windows side though. I guess I am able to see it on the MacOS side because I ran Purge wrangler. I am assuming you are suggesting I run automate-egpu
Do I need to uninstall Purge Wrangler before I do that?
I have had the option to get it to work with Bootcamp and Windows 10 before, yet at this point it goes to the previously mentioned dark stacking screen on my PC and a dark screen on the outer screen associated with the egpu.
Actions taken since the last update:
- Uninstalled Purge-wrangler
- Installed automate-eGPU EFI on a flash drive
- Re-Booted into MacOs using EFI: Result - MacOS bricked, NVIDIA card recognized
- Re-booted into Windows using EFI: Result - Windows works fine, NVIDIA card recognized
- Updated Drivers for NVIDIA. The card can be seen on GPU-Z
- MacOS not booting, which is a major concern now. Will look into Safe mode or recovery
- External Monitor not getting recognized when plugged into GPU. I have tried HDMI and DVI options. Not working at all. If I plug the external monitor directly to the laptop it works but then it defeats the purpose of the GPU as the Intel Iris iGPU would still control it
- How can I get the external monitor to work with the eGPU?
@antimony, the GTX 1060 is not gonna work on macOS Big Sur irrespective of what you try so there is no need to mess with the macOS side of things. If you really need the 1060 to work there, backup your data and then downgrade to macOS High Sierra. For Windows, the EFI bootloader is only useful for keeping the iGPU enabled when booting with an eGPU plugged in, which is required for all TB devices on pre-2015 macs (hotplug on Windows not supported). You should take a look at similar builds on this forum for further reference. Setup should be relatively simple for your Mac.
I am still tinkering with this setup. When I try to go Windows Graphics settings to add the game I want to play (Elite Dangerous), it shows me only the Microsoft Basic Render Driver. DSdiag tool also shows the Microsoft Basic Render only.
Device Manager shows NVIDIA is working properly (no error 12 or error 43).
Any clues as to what might be wrong? External display still not showing up
