Do any of you guys know how to install the nvidia drivers on a rMBP without a dedicated graphics card? I am looking into building this, and because i was planning to do a eGPU setup when i bought my mac, i didn't wanna "waste money" on the 750m. I hope you can help me.

I am running OS X 10.10.3 (14D105g) on one of my Macs. All you have to do is change 14C1510 to 14D105g in kexts and run kextcache command, but there are visual artifacts and slowness on the external monitor. Better to wait for Nvidia’s new web driver for 10.10.3.

I guess you have the 750M model, which doesn’t always detect an external monitor in OS X with the Maxwell card due to the dGPU.

EDIT: The driver for 10.10.3 is already available:

Nvidia Web Driver updates for Yosemite - New Releases and Updates - InsanelyMac Forum

Gives accelerated graphics on the external monitor via HDMI & DVI with my GTX980.

Sorry, i am very new to this eGPU setup thing. I am atm doing some research. I can't install the nvidia web driver on my rMBP 2014 15" because i have the model without 750m. Isn't it possible to do eGPU at all then?
