ticobfr Posted September 10, 2017 Share Posted September 10, 2017 Hello everyone,I've been trying to install sierra in my new external HD and I'm stuck with this screen. I read here a guy change from -v to -x and worked, so I did it and I got the apple. Before changing it I was stuck with the same result but without the apple.Thanks in advance!

WaldMeister Posted September 10, 2017 Share Posted September 10, 2017 Hi, Can you provide us with some more information about your system? Does the error occur when booting up the installation media or after you have installed Sierra? What installation method did you use?
