Magic Key board will not print all letters
Keyboard is connectedly by USB, says 100% charged and connected - will not print many letters-only some. I have checked all bluetooth/keyboard settings- says connected. I have tried US keyboard and also ABC keyboard. I have tried my wife's keyboard with the same results. Computer worked fine, and the next boot up it did not work. Tried all preferences I could with keyboard and bluetooth. Most other functions seem to work fine. Transferred photos, read email, go on the web - I just cannot use the keyboard - iMac is like 2018/19 Thanks
