#MAC PRO MID 2012 DUAL GRAPHICS CARD UPGRADE INSTALL#
What I need is to install both cards AMD and Ati drivers and then disable AMD card so that Intel takes over.
System accepted them as correct ones and then this happens. Only during the GPU detection step the screen goes mad. Can someone smarter than myself explain to me what am I doing wrong? Drivers for the Intel HD 3000 GPU always installed without any warning. Custom resolution, 3 different GPU drivers and so on. I did a lot of research up to this point. It is stretched, with maximum resolution 1280x800 (while the Intel HD 3000 card native res is 1860 x 1050), It looks like the screen is stretched beyond the LCD capabilities but I know its not true as I can get the native resolution working in MacOS and Linux. No matter what I do after installation of Intel HD 3000 graphics always ends up looking like this:
#MAC PRO MID 2012 DUAL GRAPHICS CARD UPGRADE UPDATE#
Reinstalled fresh 20 - 30 times during the last 4 - 5 weekends.Tried installing stuff in different order, drivers first, Intel Drivers Update Utility + chipset firmware updated (inf) first, update fully first, different set of drivers as mentioned above. I tried installing AMD drivers first, Intel first, I tried disabling AMD graphics in the Device Manager, I tried setting up custom resolution. Note that by disabling GPU switching, you will always use the discrete higher performance graphics card, which uses more energy. I tried installing the drivers before and after installing bootcamp for Windows 7. Generally speaking GPU switching is a great feature that should not be modified or adjusted in any way, but some advanced Mac users may wish to disable the automatic graphics card switching feature on MacBook Pro models.

I tried the Win7 64 bit driver, Win 8.1 64 bit driver, windows update driver. Laptop finishes installation, I am allowed to log in to windows and I can see two basic graphics interfaces in the device manager.

I am installing Windows 10 Pro 64 bits using EFI boot, everything works great. Found out that the GPU supposedly works great from the drivers from Windows update.
For some reason Intel decided to abandon HD 3000 graphics and does not provide the drivers for Windows 10. Few graphics glitches, not great performance. Refind allows me to switch between the installations without any problem. Fun fun fun.Script needs to be re-run if PRAM was cleared so I saved it as /boot/ FixAMD.sh in my ArchLinux. Thanks to this hack I was able to install MacOS Sierra, prepare space for unsupported on this laptop Windows 10 Professional 64 bit and then shrink the windows partiton and install Arch Linux 64 bit with Plasma desktop. What does it do? It tells the laptop to turn off discrete AMD graphics and to use Intel card. Mount -t efivarfs rw /sys/firmware/efi/efivars/ & Learn more about latest operating system.

Buy a new Mac now and get a free upgrade to the next release of OS X when it arrives this summer. Intel HD Graphics 4000 Dual display and video mirroring. This is the script I have used while booted to Arch Linux live cd. MacBook Pro (13-inch, Mid 2012) - Technical Specifications.
So far I've managed to use a EFI hack to disable the discrete AMD graphics. This laptop has a i7 cpu, 4 cores 8 threads, I've extended its memory to 8 GB and I keep trying to bring it back to life. I am not a wealthy person and I love to tinker with the hardware. Its a common fault in those machines and the users were offered a replacement - there was a special recall program which ended long before I got my hands on this laptop. The discrete graphics in the laptop (AMD Radeon HD 6750M) is dead. This machine as many of its generation was dumped because of a graphics fault. I myself am running a sapphire r9 290, but it does not work with OSX out of the box, and will never work well.I own a MacBook Pro 2011 A1286 which I got as a freebie from a friend who saved it from the corporate dumpster. If you go with either of those, do some research to see which manufacturer works best as the card needs to be a "reference model", which means not tweaked much by the manufacturer. With AMD I think the newest card that works with no issues is the 280x, and with Nvidia I think the 780. If you don't care about the boot screens (again, they can always be accessed by swapping back to an older "mac" GPU) then you have plenty of options. If you want to retain the boot screens, then you need to buy flashed GPUs from: (or flash them yourself), or get the last "mac edition" card released: You can always swap in an old Mac GPU if you want those screens, but that is an extra step. With a PC card, you cannot access those screens. There are a great many PC GPUs compatible with OSX, but anything that isn't a "mac edition" will not have boot screens, which are menus/interfaces that can come up before the OS loads - i.e.: holding option to choose boot drive, or holding option-r and booting from the recovery drive.
