@tusctodd Thanks I will try this tonight ! I hope this will solved this problem !

@Dschijn the only way I saw to restore EFI partition is to do clean install of the hard drive. @Light Actually you can't use internal screen on Windows 10 imho but look at other post if there is an upgrade of drivers

Ok nice ! In 2016 i will buy an external screen Thanks for u'r reply !

Yes the device is show as u can see on attach files.. I'm running on stock settings. Today i run the test again and my score is 1046. I attach the CUDA Z and Valley benchmark result.

Hi, finally it works, I plug the tb cable on the same time of the boot chime and it works 100% of time ! I run Unigine Valley Benchmark in full screen 1920x1080 on internal screen and I have a score of 850 it is normal ?

Hi TYRTlive, u can use internal display only on Windows, u must run windows 8.1 it is more stable. Take a look at Evo's guide https://forum.techinferno.com/index.php?/forums/topic/6727-guide-macbook-enabling-optimus-internal-lcd-mode/ it will help u Good luck

Hi all, Now, I do my first eGPU with my setup : 2015 rMBP 13" with Intel Iris 6100 and 2,7Ghz i5. My eGPU is an EVGA GTX 950 2go in an Akitio enclosure with a corsair 430 PSU My problem is, when I boot in win 8.1 (to have Optimus) everytime I hva a Black Screen or the Windows Boot circle and after 10 minutes a black screen... Before doing this EFI mod I can boot into win 8.1and I saw my GTX 950 but I can only set Iris 6100 for the internal display EDIT : I do a clean install of all and I reinstall Os X 10.10 instead of 10.11.2 (to try) I'll install Windows 8.1 via Bootcamp and try to set GTX 950 for my internal screen. How to see if the eGPU works on internal screen ? In PhysX ? (Sry for my bad English... )

@Dschijn thanks I will try this when I get the PSU !

@Dschijn thank you, so I have to install Win 8.1 ? My eGPU will not work on OS X without external screen so ? Sorry for questions, i'm newbie in eGPU. Edit : I see that I can use my eGPU with OS X with u'r link (Thank you !!! ) I have another question I have my PSU and to power correctly my Akitio I have to make a barrel, so I bought a barrel plug and I have a 2x Molex to 6 pin so I have to cut the 6 Pin cable to plug it into the barrel 2,5x5,5 mm ?

Hi all, today i buy everything i have to use to make my eGPU so I have my enclosure (Akitio Thunder2), my GPU (MSI Nvidia 750TI 2GO OC (the one fan version to fit in the enclosure)) a PSU Corsair modular 450w and a barrel DC plug to connect to the Akitio. My question is : when everything is plug in how can I install drivers on OS X El Capitan and enable Optimus ? (I have an rMBP early 2015 13" without dgpu)

I wanna use the 1 fan model MSI GeForce GTX 750 Ti OCV1 2GB (N750TI-2GD5/OC) : achat / vente Carte graphique sur ldlc.com do u know where I can found a tutorial to make a Barrel ? I have another question with this can I use my internal Retina screen or I have to plug the e-gpu to an external monitor ? I'm on El Capitan / Windows 8.1 / Windows 10

Yeah thank u man, dunno what is better to use ? A desktop PSU or Dell DA-2 ? Have u got feebacks ?

Hi all, Sorry for my bad english, I'm french and I have a rMBP 13" 2015 (256 SSD - 8 ram - Iris) and I wanna try to do an eGpu. But i don't know what I have to buy... So imo i have to buy an AKiTiO Thunder2 and i want a Nvidia GTX 750Ti from MSI. Is it all i have to buy ? Thanks for u'r help.
