Hello, I’ve done this download several times & it is not working for me at all. I restart my computer several times as well and Keyman is still not active on the menu bar. There are times when Keyman will appear to be active, however, when I go and click & move to ‘Configuration’ it’ll ‘disappear’ and not work again. I’ve looked at other posts with people’s same issue on this & nothing appears to work.
It’s possible that the security settings are out of sync. I would suggest trying to reset the security settings for Keyman in MacOS by executing this command in a terminal window: tccutil reset All keyman.inputmethod.Keyman Running Keyman should then prompt to approve the security settings again and allow Keyman to run properly.
