Go to the Applications section of the hard drive.
Open the Utilities folder within the Applications section.
Double-click on the Activity Monitor icon to open the utility.
Search for “Air”
Highlight the row that says “Air” and the row that says 'Air Flow' (look for the app icon.)
Click the “X” and then click “Force quit”
Restart Air
