You should upgrade or use an alternative browser. I have somehow erased my iOS operating system off my iMac 27! I had followed a few YT videos, but still screwed up!
Currently, I have on screen .. a white screen with a grey 'no-entry' sign in the middle. I cannot get passed that screen, and I've tried everything possible on apple support and further YT videos, with no success!
Can anyone help me restore please?
Much appreciated.
