I have a Qwerty keyboard on my MacBook Pro late-2015, set to the standard US layout, that I sometime use to write French accentuated characters.
However, since the last OS X update, some accent shortcuts are not working anymore. More specifically, Option6 (+ some vowel), which used to produce circumflex accents now writes
§, and Optionc, used for c cedilla, is now used for capitalising the last written word. I can still write these characters using the press and hold method, but it's pretty inefficient.
How can I re-enable these accent shortcuts?
