Hai, very usefull guide.
But I have no keyboard, mouse works.
In the setup of el capital the first keyboard use is filling in name etc, there my keyboard doesn't work.
During setup from usb, loading install to HD keyboard ok after reboot and booting from HD (SSD) into OS X partition I
come in install menu, language, keyboard choose, network etc till name etc
I suppose modification should be made on OS X HD and not USB or
modification to usb and reinstall?
Who has a clue?
