I present my little tool that allow to get display output on nvidia eGPU (aka external GPU) connected to mac via TB (in OSX)
an example of such setup on screenshot - mac mini 2014, TB2, Akitio box and gtx670 videocard.
How it's gonna work:
the tool costs 20$
If you want to get it:
1) make sure cuda already works on your setup (get cuda-z to check -
http://cuda-z.sourceforge.net/ , you should see your card in list of cuda devices)
2) collect some information about your mac eGPU system, I will need:
a) ioreg output, do this command in terminal (if eGPU is connected - better):
ioreg -l -w0 > ~/Desktop/ioreg.dump
b) your mac model, display model (display/displays you want to use with egpu, just in case)
3) send me the file ioreg.dump (you will find it on your desktop, after doing step 2.a), your mac model and display model to email -
bobahu4@gmail.com subject: "egpu Display"
4) if everything is fine and your mac can be enabled, I will answer you and will send you paypal link
5) Make donation of 20$ with the link I sent and I will send you the package
6) Install package, reboot, enjoy
TL;DR: collect data, send me, wait for answer, pay, get package, install, reboot, enjoy
Details about this tool:
it allows to enable display plug detection on eGPU (in OSX), multiple displays supported, card will work just like in classic mac pro.
it survives update, I have tested 10.10.4 beta, additional reboot needed after update installed, then everything works again.
I can't guarantee Apple won't break this with future updates, but I'll try my best to fix it if they do so (I have such eGPU system as well).
The tool needs kext-dev-mode=1 in your boot-args, but you probably already have that if cuda (see step 1) works for you.
Supported macs: TB2 macs except Retina Imac, TB1 macs shouldn't have such issues.
Tested machines to work: rmbp mid 2014, 13" and 15", macmini late 2014, MacPro 2013
I'm in trouble installing eGPU on my Mac mini 2011. Can you give some assistance?
I made the usual procedure for TB1 machines with a GTX 470, and I actually got it to work, BUT only with Mac default drivers and I can't use the eGPU on startup, only connecting the monitor after the system started (and it's not always working). Seems that the graphics driver isn't starting on boot even with nvda_drv flag on boot-args. I saw that some users got in trouble to use GTX 470 graphics on boot in newer macOS versions, but I don't think I have the same problem since I can still "use" it as I meant before. The problem is just when I restart the monitor signal from the card stops and I'm forced to use internal graphics again.
Thanks in any advance.
