Have you ever had an unexpected direct phone call from Apple support? I have not, and if you do ever receive one, you probably aren’t talking to Apple. The company says you should immediately hang up.

Don’t fall for it
Other things it warns against are suspicious calendar invitations in Mail or Calendar, annoying pop-ups in the browser, unexpected software download prompts, and fraudulent emails.
