Open a link in new tab in Safari on macOS Sierra Before macOS Sierra I could open new link with command-click in Safari. It doesn't work anymore.  What's the shortcut in macOS Sierra?
⌘-click works fine for me in Safari under macOS sierra 10.12.

Check that ⌘-click opens a link in a new tab is checked under: Safari > Preferences... > Tabs

If it's checked and not working, uncheck it and close Safari. Then Open Safari and check it. Does it work now?
