On my MacBook Air MacOS 15.6.1. (24G90) when i click the X in the top left corner of "Notification Boxes" of Mail Messages etc., nothing happens, the box DOES NOT CLOSE. How do I close notices when the X does not close the notice?
Do you mean the notifications in the Notification Center at the upper right, like this?
Have you tried rebooting your Mac? See if the problem is present when you boot in safe mode, which disables 3rd party extensions and performs some system cleanup.
I tried to open in Safe Mode and although I followed the instructions very carefully to open in Safe Mode, I did not get it to do that. Not sure why, but I just never remember to automatically reboot! Anyway it seems to have worked, so THANK YOU for the suggestion/reminder, all sorted.
X Does Not Close The Notification.
