How to Exit a Stuck E-Mail client on MacOS Sierra

Usually, Macs run and preform fine.  But sometimes, you may need to manually close an app because it has become stuck (or unresponsive).  Fortunately, Macs have an easy way to do this from the Terminal.

We’ll be using Apple Mail for this example.

While in Apple Mail, you notice that you want to close the email client, but it doesn’t close and the normal ⌘Q option is grayed out.

1. Open Terminal (Finder > Applications > Utilities > Terminal).
2. When the Terminal Window opens, type: killall Mail
3. The Mail app will then close.

• Only do the above as a last resort, as it may corrupt some necessary files needed for Mail to open the next time you want to use it.
