Right-Click Menu Disappears from Finder on Mac

Go to System Preferences >> Extensions. With ‘All’ selected on the left hand menu, scroll down on the right side and look for “SecureCircle.' You will see a ‘Finder Extensions’ checkbox. Uncheck and check the box, or check the box if the box is unchecked. This should restore your right click menu.

The right click menu can disappear when multiple applications try to take control over the right click menu and Finder icons. Mac OS only allows for one icon to be present at a time.
