eGPU not detected 🙁 - MBP 13' TB2

Hey everyone! Thank you for your time reading this before anything.

Ever since I purchased my setup I haven't really got it too work well and have kind of spiraled into frustration. I really was just wondering if any of you guys' expertise could help me get my noobiness together and solve it for once.

I'm using a 13 inch MBP from late 2014 with macOS 10.14.6 and thunderbolt 2 on it.

The GPU is an RX480 8GB and I'm trying to run it through and Akitio thunder2 node.

For the PSU is a 500W EVGA.

- I start the setup with a "paperclip trick" little adapter I found online and the PSU theoretically starts (though I read online if you had the position wrong it could only "partially" start so I'm not sure if maybe the mistake could be there).

- The Akitio thunder2 node lights blue and the green lights and my mac detects the Akitio Thunder2 piece, but not the GPU itself.

- The GPU fan doesn't spin, though I've already separately tested the card and it ran just fine 🙁

- Everything is I think connected it's just that the GPU itself is never detected.

- I've installed purge wrangler and ran the automate.egpu script for my card.

I'm honestly so frustrated and depressed by this 🙁 Does anybody maybe know what it could be?

Thank you again

@giancarlo_rc, Apple only provides eGPU support for Thunderbolt 3 and newer Macs. Thunderbolt 2 Mac like your 2014 13-in MacBook Pro does not work right out of the box. Fortunately we have community support in automate-eGPU EFI boot loader and Purge-Wrangler script. My recommendation is to install Purge-Wrangler script in macOS 10.14.6. After that the AKiTiO Thunder2 + RX 480 eGPU will work.

@itsage, Thank you for your response :))

Yeah unfortunately I've also tried that though :/

It think it seems like the problem is more on the hardware rather than on the software side as I remember I once was able to successfully start the setup but I recall the fan got like stuck between some cables and then crashed because of temperature. I thought this could've meant the card had burnt but I was later able to test on other hardware and it seemed to work just fine, not mine anymore though :/

At one point it used to be it'd detect it, but not work, but unfortunately now, even with all patches and automation done on the software part, it just doesn't detect the card, because the akitio node seems to work and the software as well, but from the beginning, the card's fan just won't respond either.

My guesses are that either the PSU is maybe on some sort of "low voltage" and powering the Akitio node but not the GPU (due to a wrong "paperclip trick") or the Akitio node itself is damaged in some way that it turns on and responds to the thunderbolt but not the PCIE slot (since the card has been tested to work). What do you think?

(On startup it just says eGPU not detected when booting from EFI and on the system report it just reads the akitio but not the card after all PurgeWrangler and automate.egpu patches :/ )

Thank you so much for your response again
