Having a problem getting a bootable USB to work
However, when I boot from the USB this time, it all works fine until after I select boot from the USB. I select the USB, I get the progress bar across the screen, BUT THEN... I get graphical instruction from Apple to turn a mouse or trackpad on (I am using a 2014 Retina 27 inch iMac fusion). I toggle both my Apple mouse and Apple trackpad on and off but it doesn't get past this. So I just turn it off and give up, having been caught.
Please tell me cohorts, where have I erred? Or should I shake my fist at someone?
