Hello @Shadow_Bullet, I would like to congratulate you on your successful build. I myself am about to build one which is very similar to yours, which is a MBP13 Late 2013 + GTX 970 + Akitio + OS X 10.10.1 I have some questions to ask regarding your build. Hope you are able to share some of your experience. 1. How did you power your Akitio PCIE board ? with a powered riser or with the Atikio adapter ? from you pictures it seems like you are using the Atikio adapter, I’ve read on other threads that the power from the adapter isnt sufficient enough and may experience some problems. 2. From your pictures, I can see that you were able to fit in a full size GTX 970 card onto the Atikio PCIE tray, did you have to modify the tray in order to fit the card ? I’m planning to build a custom case or maybe to buy a mini itx case, but if the Atikio tray can be still be used to hold the GTX 970, I wouldn’t mind saving some money and time using your method. 3. On OSX, I read that you were able to sort out the default driver issue on OSX. Have you experience any lag or delays when using software tools like adobe illustrator or video editing programs or any work softwares ? on another thread someone posted experiencing delays/lag when running softwares like adobe illustrator and after effects on OS X + EGPU. 4. As an everyday use setup question. My Macbook usually stays at home but occasionally I will take it out to work outside from home, I almost never shutdown my Macbook and I usually put it to sleep mode even when I’m travelling with it in my bag. My question, when getting home and reconnecting the macbook to the EGPU do you need to restart OS X in order for the EGPU to be working or is it simply by reconnecting the EGPU thunderbolt cable OS X is able to detect the EGPU without requiring a restart ? 5. Have you tested any native OS X games - Steam ? any issues ?
