Question:

Question: My Macbook Pro Screen flashes black once whenever I open my online banking browser. Is my mac being hacked every time this happens? What does this mean?

Whenever I am about to sign in to Natwest online banking my Macbook Pro with Retina Display flashes black once very quickly.


It's been happening for a few months now and it doesn't occur in any other situation or with any other website.

MacBook Pro with Retina display, macOS Sierra (10.12.6)

Since it flashes black before you sign in, then perhaps someone without an account can duplicate it.


Please provide that site's URL.
