How to stop clicking sound & icon now appearing in upper right hand screen corner when using the shift key on macbook pro retina,15-inch, mid 2014, with 2.5 GHz Intel Core17, running 10.13.6 high sierra?
How can I stop a weird clicking sound & icon now appearing in upper right hand screen corner when using the shift key (icon disappears when shift key is released) on my macbook pro retina,15-inch, mid 2014, with 2.5 GHz Intel Core17, running 10.13.6 high sierra?
The icon is a command symbol or an upward arrow and until I recently upgraded to OS 10.13.6 from Yosemite, this strange behavior never occurred.
I would appreciate any help you can give me to resolve this problem.
