|mmm yellow exclamation marks (in more than one device) suggest more than a few issues...|
Can you list the assorted devices showing/flagging yellow exclamation marks?
Possibly a "repair" installation might resolve a lot of the problems.
Perhaps consider it and follow the steps here:
Note it is not done via Recovery Console.
Presuming you can at least boot into either normal mode or safe-mode you might also consider running this utility as it does what it says on the tin. It works as described.
Will resolve al maner of problems. It's free (though they do appreciate a wee donation) and well regarded. It run from within a booted OS - ideally safe-mode although "normal" mode is OK too. If possible use safe-mode.
