	8	These instructions will completely erase the files on computer you are installing to with no chance of recovery. Make sure you have backed up and saved everything you need before you start this process.
	9
	10	We will also use and erase the USB drive we will use to create the install media. Again, make sure it doesn't contain anything valuable before you start.
	11	{{/warning}}
	12
	13	1. Start with a 16GB USB drive. This USB will be erased. In our example, the USB is labelled "MyVolume"
	14	1. Download the Catalina installer for 10.15 ( [[https:~~/~~/support.apple.com/en-in/HT201372>>https://support.apple.com/en-in/HT201372]] ) from the apple app store (8GB). After downloading, the OS will try to run the installer and fail giving an error message. Just dismiss the dialog window and continue on.
	15	1. Run "createinstallmedia" via the terminal window to create the installer:
4.2	16	11. ##sudo /Applications/Install\ macOS\ Catalina.app/Contents/Resources/createinstallmedia ~-~-volume /Volumes/MyVolume##
10.1	17	[[image:macos-big-sur-terminal-create-bootable-installer.jpg]]
9.1	18	11. Eject the installer USB
	19	11. Insert the installer USB into the computer and power it on while holding the Option key pressed until the boot selection screen appears:

	24	11. Use the disk utility to erase the Big Sur drive and then exit disk utility
	25	11. Install Catalina as normal.

3.1	30	== Disable MacBook Pro Dedicated GPU ==
	31
	32
	33	Important Notes:
	34
	35	* I have recently come up with a MUCH better, PERMANENT solution to this issue, which I'd recommend using instead, if your AMD GPU has failed. This method will also allow brightness control and sleep mode to continue working as normal. More info can be found [[here>>url:https://doslabelectronics.com/Demux]].
	36	* After performing the steps below, sleep mode and brightness control will NOT work properly on your system.
	37
	38	1. First, ensure your machine is completely shut down (You can press Control + Option + Shift + Power keys to reset the SMC).
	39	1. Now, boot your machine while holding the Command + S keys. As the system boots, it should display white text on a black screen, and should eventually stop at a prompt.
	40	1. At this prompt, enter the following command and press Return:
	41	##nvram fa4ce28d-b62f-4c99-9cc3-6815686e30f9:gpu-power-prefs=%01%00%00%00##
	42	1. Next, enter reboot, and press Return.
	43	1. Immediately after running the reboot command, hold down Command + R (if you're running OS X 10.11 or later) to boot into Recovery Mode. If you don't have a Recovery Partition, you can boot from a Mac OS installer USB drive.
	44	1. Once booted in Recovery Mode, open Terminal, and run the following command:
	45	##csrutil disable##
	46	1. Reboot the system.
	47	1. Once the system reboots, it should now successfully boot into your install of OS X. Now, you'll need to download the program found [[here>>url:http://dosdude1.com/apps/MacBook%20Pro%20dGPU%20Disabler.zip]].
	48	1. Run the program, follow the prompts, and enter your password when prompted.
	49	1. Once the tool finishes running, your system should now run without the dedicated graphics, and should work completely normally.
