That's because it's a Mac Mini 2012 and not a MBPr 15" 2014... The hardware used is important, it's not about the OS version or anything software related. MVC already gave you a hint to this, though.

It's a pain that Apple seems to restrict the use of such experiments.

MBPr 15" 2014 doens't provide external screen support in OS X with an Nvidia eGPU, you can only use it for CUDA/OpenCL. AMD cards work though.

At least for now it's this way, read this as reference -> http://forum.techinferno.com/diy-e-gpu-projects/8507-no-kext-loaded-gtx-970-akitio2.html

Thanks for the reference, Morv.

Altough this guy seems to be getting the expected results link.

Jojow,

Sadly it has basically been discovered that many TB2 Macs have become more trouble to eGPU with then the TB1 Macs were.

I have a thread where I have tried to group the info.

I only tested once on a rMBP 15" with Iris only but in my experience it would not output video in OS X without a specialized EFI rom.

Amazingly, all of the TB2 Macs I tried had this issue while another guy tried different TB2 Macs and they all worked to some degree or another.

Windows seems to be easier to get external screen output for most.

Thanks a lot!

How and what kind of display did you connect to the eGPU?

I just connected one FHD monitor via the DVI-I port. The card was in my desktop before, so I'm quite sure that it is working properly.

I have set up my MBPr mid 2014 15 inch with Intel Iris Pro with the Akitio thunder2 and a gtx 660ti from nVidia, however after all drivers were installed and all kext files were edited, I'm still not able to use the card as preferred. It is being recognised as shown below.

I'm able to use the external GPU to render in blender using CUDA, but it's not able to use it as an outputting device nor as a default card. Is there any way to fix this? Thanks in advance!
