Fake virus pop-up or 'Apple' call? Mac tech support scams

A pop-up that says your Mac has a virus and shows a phone number, or a caller who says they are from Apple, is a tech support scam rather than a real warning. Close it safely, and know what to do if you already called or let someone connect.

What that means

Low risk. This fix only checks things, or changes settings you can switch back in the same place. This change is reversible — you can return to the previous state without professional help or data loss.

Steps

  1. Don't call, don't click, don't pay

    Apple says pop-ups warning of viruses on your device are scams, and that it never asks for your password, passcode or two-factor code

  2. Close the pop-up without touching it

    You should see: The browser opening on an ordinary page, with no alert.

    Why?

    The pop-up is a web page built to fill the screen. A web page cannot scan your Mac, so nothing it says about your files is true.

  3. If you only saw it, or only spoke to them

  4. If you called them or let them connect, cut them off first

  5. Then protect your money and your accounts

    Why?

    Report Fraud replaced Action Fraud on 4 December 2025; the phone number, 0300 123 2040, did not change. It takes reports from England, Wales and Northern Ireland. In Scotland, report to Police Scotland on 101.

How to verify the fix

The pop-up is gone and does not come back when you reopen the browser, no app you were told to install remains in Applications, and your bank knows if money or card details were involved.

If this didn't fix it

Get professional help if they were connected for more than a moment, if you typed passwords or bank details while they could see the screen, or if anything unfamiliar appears afterwards. Reach Apple Support through apple.com, never through a pop-up or an unexpected call. When you cannot be sure what was done, erasing the Mac and setting it up again is the safest answer. The 'Erase and reinstall macOS' fix has the steps.
