Why does a ^ (caret) appear after the number when I type the number 6?
On Mac computers, the default keyboard input needs to be "US" and not "United States-International." However, this setting appears not to "stick" and you will need to change it each time when it resets.
To change the setting you need to access the Language Bar, which should appear on your desktop.
If the Language bar isn't listed in the Toolbars menu, you don't have multiple input languages installed on your computer. You need to add additional languages using Region and Language in Control Panel. For more information, see Add or change an input language.
