I have a Macbook Air. Running El Capitan with British keyboard layout. I have enabled Chines Simplified Pinyin input. I am trying to type the tone marks. For example, pressing opt+a followed by u is supposed to produce ū. This doesn't work however. Any advice?
I have seen mentions of US Extended Keyboard or ABC extended keyboard layout as being the culprit. While this makes 0 sense to me, I have replaced the British layout with this ABC Extended one. While now I can type the accented characters in it, they still don't work in Pinyin. This is extremely annoying.
