Hello, I have a 2017 13" MBPnTB. If I plug a Razer Core X enclose, does that mean the other TB3 port is disable or useless now? I would like to plug my eGPU to the first TB3 port (the one close to display), and be able to use the second TB3 to connect my mouse. Can I do that? I am sorry this is a very noob question, but I can't find an answer anywhere.

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

I ran the "set-egpu" script today and can no longer get a connection to my external monitor. Yesterday I was running fine from the egpu to the projector via hdmi from the box to the projector. I ran the script today to work internally and tried to go back to my projector but am just a getting black screen.

Hello! Am I allowed to post here? Everything is a little daunting and I am not sure where to start.

Mid-2012 Macbook Pro, Non-Retina, NVIDIA GT 650M. I have purchased the Kareon Kable "Dell DA-2 Power Supply) Akitio Thunder to 90 Degree 6-Pin PCI-E Cable", as well as the Dell DA-2 Power Supply adapter.

I am using the Akitio Thunder 2 with an EVGA GTX 1060 6GB. I've been doing my best to follow all the guides available, specifically enjoy's, ozzy's, along with a number of other threads... I'm beginning to get at my wits end. I have been e-mailing with Nando and he believes there is a power supply issue, and while I wouldn't doubt it, I haven't the slightest clue where to begin. I have begun an email to Kareon Kables inquiring about a possible replacement - I do not have the means to solder parts together, I'm aiming for most plug-and-play possible. It's within my grasp, it seems to just be one thing that I'm missing 🙁

Thus far:

MacOS: I have 2 Mid-2012's, however the one that I use is Mojave. It seems there's just the fact that I have to downgrade for that. Unfortunate, but doable, and I may not even do so because of how little I use MacOS. However, to troubleshoot, I hotplugged my setup into the other laptop running high sierra. I do not know if it would have automatically appeared (it did not), and I was unable to try nvidia.purge.sh and purge.wrangler.sh (or whatever they are, you know what I'm talking about! Smile ). 

Windows 10: So, a reinstall would be awful because it would be the literal 14th fresh install that I've had to do on this computer. *However* I do have a 750GB HDD that I want to replace my current secondary internal HDD (do not worry, primary disk is an SSD), and from what I understand, in order to get 325GB partitioned for both MacOS and Windows 10, I would need to do something pretty close to a fresh install anyway. ***If*** I can get away with not reinstalling Windows 10, that would be great.

Solution 1: the current automate.egpu.sh through EFI seems to be the next best bet, however for some reason Windows 10 isn't booting. That doesn't matter much though, because the program doesn't detect an eGPU. That seems to be the issue everywhere I look.

Current problem: In working with Nando through e-mail, setup 1.35 simply doesn't detect the GPU either, no matter the physical steps I take.

My current steps to attempt to get the GTX to power on are limited. I can unplug and replug 4 sources:
The GTX 1060 PCIe chip to the Akitio PCIe slot.
Akitio Power (provided from the DA-2, split with the Kareon Kable)
DA-2 Power directly, or the Kareon Cable adapter which plugs into the DA-2 power source.
Plugging in the power to the GTX directly.

The GTX reacts when I "touch tips" of the male (GTX) and female ends (Kareon), and the fan on the GTX and the Akitio will begin to spin. The GTX will always stop as I finish plugging in the cable securely.

Currently, I am in Windows 10 with the GTX plugged into the Akitio, which has a Thunderbolt cable (I have an Apple thunderbolt, as well as the Akitio one that was provided, both the same results) plugged into my Macbook Pro. There are 2 blue lights and 1 green light on the Akitio, and the GTX fan flickers every 15-30 seconds. However, if I hotplug it (unplug and replug), this will stop and not begin again. Furthermore, in device manager, the only display adapter is my dGPU, the 650M.

My next step will be to use the High Sierra 2012 Macbook Pro and use the .sh files to see if the eGPU is detected. However, beyond that I'm not very sure what I should begin to do. 

I'm not well versed in power supply, and can understand that the GTX is getting power, but potentially not enough. While it seems that the DA-2 provides enough power, my issue may lie in the splitter that I am using? If this is the case, please recommend a splitter - I would really appreciate the ability to purchase it in compact. Buying 2-3 items and the connecting them is not ideal 🙁

Finally, I understand that this is likely not the ideal location for my post. I will be making a post (when I find where and how to), as well as commenting elsewhere as well. @mac_editor, the last post was 6 months ago, any chance you're still around?
