Mac keyboard unable to type the at symbol and a few other symbols are not working either
I updated my Mac with the new update. Worked fine this morning but when I used it again a few hours later the keyboard is not functioning as it should. I have turned the machine off and restarted, no change in function. The keyboard settings are for US and I also restored the default keyboard shortcuts. When I push shift 2 instead of the at symbol I get this ", same with shift 3 I get · instead of the pound symbol etc....
