How to Install/Run OS X El Capitan on an unsupported Mac Pro

This is how to install Mac OS X 10.11 “El Capitan” on an unsupported Mac Pro. In this video, I use a Mac Pro 1,1 (that has been flashed to 2,1 firmware). To do this, you’ll need another Mac that supports El Capitan, an upgraded graphics card for your Mac Pro, and an 8 GB or larger USB drive to use as the El Capitan installer. You’ll also need a modified version of boot.efi, which you can download here:

Mac OS X Bootable USB Drive Creator: http://dosdude1.com/apps/Mac%20OS%20X%20USB%20Drive%20Creator.zip

The command you need to run in Terminal to make the bootable El Capitan USB drive is:

sudo /Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/createinstallmedia –volume /Volumes/elcap –applicationpath /Applications/Install\ OS\ X\ El\ Capitan.app –nointeraction

(You’ll need to make sure that “Install OS X El Capitan.app” is located in your Applications folder for this command to work.)
