Fullscreen doesn't work
Hi
My fullscreen green button does not work in any app at all, on Macbook Air. Does anyone know how to solve this problem? Safari doesn't want to go fullscreen, neither iTunes, YouTube etc.
MacBook Air
Close all windows and quit all applications.
Hold the option key down and click the "Go" menu in the Finder menubar.
Select "Library" from the dropdown, then "Preferences" folder.
Look for this file.
com.apple.finder.plist
Right click on it and select " Move To Trash" from the contextual menu.
Restart the computer.
