Your USB device will appear as something like /dev/disk2 (external, physical). Open /Applications/Utilities/Terminal in MacOS and list all storage devices: First, you need to identify the USB device.Then you could either simply burn this ISO to CD/DVD (which later could be either inserted to MBP's SuperDrive or External DVD Drive connected to MBP by two USB cables) or create a bootable USB.ġ.2 Creating the bootable USB with the.Download the latest Arch Linux ISO image.You need a working computer for that and a spare CD/DVD/USB drive.Prepare a Bootable USB pendrive with a non GUI Linux Searching in internet, I stepped into this GitHub issue explaining you may be able to replace steps 1 and 2 with the following command, that you can execute in Single-User mode (boot pressing cmd+ s): sudo nvram fa4ce28d-b62f-4c99-9cc3-6815686e30f9:gpu-power-prefs=%01%00%00%00ġ. The procedure described in the steps 1-3 worked for me until macOS Sierra, but with the upgrade to High Sierra, I started getting a pinkish/reddish screen and I was unable to enter Recovery mode to repeat step 3 as I had to do in previous upgrades. You can permanently disable discrete graphics card following next steps: UPDATE! Try to edit NVRAM variable from Single-User mode Is that true? And if yes, how to do that? I heard that the same EFI setting is responsible for not even showing the integrated GPU to other operating systems than macOS and you have to trick it somehow to think it's macOS. If I disable the discrete GPU from EFI, will macOS think that the integrated GPU is the one installed and will it let me use multiple monitors with it? If you force integrated graphics in GfxCardStatus, Mac OS X (up to Yosemite at least) doesn't allow you to use multiple monitors (even though the built in Iris Pro can do it). The question is basically whether the command mentioned in GfxCardStatus github issue comment here is correct or not, and how to undo it if it doesn't work.Īn answer to this alone is a correct answer, but it'll be awesome if you can also tell me: I'd also want to know how to undo it if needed. I assume this is persistent across multiple reboots. How can I disable the discrete GPU from EFI? I know I can use GfxCardStatus but I read I could have a more permanent solution by changing some EFI flag. I'd like to disable the NVidia GTX 750M GPU on my MacBook Pro 15' (Retina, Mid 2014, Mac OS X 10.10 Yosemite).
