- You can choose the Apple menu and click on Force Quit.
- Alternatively you can simultaneously press ⌘ (the Command key situated next to the space bar), Option (the key right next to it) and Escape (the key located at the upper left corner of your keyboard).
- If you have done it right a dialog box titled Force Quit Applications will open up.
- In this new dialog window select Safari, then press the Force Quit button, then confirm with Force Quit again.
- Close the dialog box/window.
