Help Macbook Pro 2012 with Akitio Thunder 2 Implementation in Apple eGPU discussion Posted March 12, 2018 · Edited March 12, 2018 by TechAce Hello, I need help trying to put my setup to work. I recently purchased an Akitio Thunder 2 with a GTX 1050 ti Superclocked to implement it as an eGPU for my system. I have a Macbook Pro 15” mid 2012. I’m not interested in using it with OS X (I’ve read that there is not much support by Apple for Nvidia cards Series 10). My main goal is to use it using Windows 8.1. I had some trouble with the initial connection as Windows recognized the external card but it gave me error code 12. I already got rid of the error 12 problem. The situation now is that I connected a second display through the HDMI port of the eGPU and activated it using the Nvidia Control Panel. After a restart I choose to boot windows 8.1 again but the two displays get hanged with black screens and I only see the cursor. Anybody has had this problem and was able to fix it? I did some further testing, decided to boot up with the eGPU connected but without the HDMI cable plugged. I was able to log in to Windows and the eGPU got recognized in device manager, but then I connected the HDMI cable and for one second I saw my Macbook screen displayed in the external monitor, then both screens hanged again with black screens only showing the cursor. I’m exhausted of experimenting and seeing no positive results... My goal is to be able to use the eGPU with the internal monitor of the Macbook (if that is possible with my system). If not, I would like to know how I can set it to work with a second display. I will be very grateful if somebody can help me... Sorry for the long post.
