Ok, so in theory, if you get Intel hd graphics to activate and accelerate the internal lcd with the nvidia gt 650m disabled via device manager, you basically activated nvidia optimus, therefore when you have a egpu, it will be able to accelerate the internal display as I understand it? If that's so, then I will try the same process used to activate the iris pro graphics used in the thread you listed when I have time this week.Ĭorrect on all counts except the first trial run test you'd be wanting the HD4000 to connect to the internal LCD AND have the GT650M active. There's a workaround to eliminate the external LCD (Chung-gun or Ultramon) by using a dummy VGA plug to create a phantom external LCD. Until then the best you can do is drag windowed apps ran on the eGPU attached LCD to the internal LCD (powered by the GT650M). If you can do the same as done there then all that's needed is to disable the GT650M to have the NVidia driver activate Optimus accelerated internal LCD mode. However, since then there has been some success activating the iGPU on the 2013+ GT750M model at The reason is that the a working iGPU wired to the internal LCD hasn't been possible to activate on that model. Internal LCD mode hasn't been done as yet on the 2012 15" MBP under Windows. Samsung 850 Pro 1TB (Mac OSX and Windows bootcamp bios) MacBook Pro 15" Mid 2012 Non Retina (Model: 9,1) Note: I haven't bought any of the hardware yet as I want to make sure the egpu will be able to accelerate my internal display.Įdit: So Windows 10 Optimus is broken? If that is the case I can put Windows 8.1 on the drives if that's the case Is that possible, and if so, does it work on both bios and efi based Windows based installs? Thanks! The reason why I'm stating all of this is because I want to have a egpu using the Akito and a gtx 950, and I want it to accelerate my internal lcd display. These issues are fine because I have two drives that I can swap in and out where one is bios and the other is efi.
I did finally get it installed but with Intel hd graphics drivers not wanting to install (I will try to get it to install when I have more time this week), and the notorious sound not working issue which up to this point, I don't believe there has been a workaround found by anybody. The problems are that since my model was one of the last macs to use bios via boot camp and not properly support efi, I obviously ran into issues. So, I started by installing Windows 10 in efi on my MacBook Pro.
As I understand firstly, egpu support is more or less plug and play on Windows in efi mode. I'm planning to start my first EGPU project on my MacBook Pro. I'm new to this forum so my apologizes if I screw something up with this post.
