Volume icon pops up randomly in response to unrelated keyboard inputs

The volume icon keeps popping up at random, in response to unrelated keyboard inputs. It just did it now when I pressed the letter “F”, and earlier in response to “command z”.


Any suggestions? Thanks : )

Did you try an alternate known good keyboard to compare behavior.




  To trouble shoot further you can:


  Try a SafeBoot https://support.apple.com/en-us/HT201262


  Takes noticeable longer to get to the login screen, does a 5-15 minute disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache,  etc.  

This test will tell you if third party interference; extensions etc are not loaded in safe boot mode. 


  Test issue in another user (or guest user) account  https://support.apple.com/en-us/HT204443

  This will tell you if it a universal issue or isolated to your user/admin account. 




you can Try resetting NVRAM/PRAM http://support.apple.com/kb/ht1379
