Zinskynots Pop ups

If these are sliding in the from the top right of the screen, a site you visited has given itself permission to send push notifications. Everything you're seeing is nothing but a scam.

Open Safari's preferences. Click on the Websites tab and then scroll down to Notifications. Clear any entries in the right hand window. You might find something similar in the Pop-up Windows heading below that. Block any you don't recognize.

Then if you want, uncheck the box to the right, as shown below here.

I personally can't think of any reason why I would ever want any website to push notices to me.

Kurt, new version of Safari doesn't have "Preferences."

Yes, it does. I'm in it right now, in Sequoia, with the latest release and the newest version of Safari. But I see what you mean. I said preferences. It's now called Settings. Same basic thing.

The notifications in the System Settings are different. Any there will be associated with software directly on your Mac. Whether that's apps included with the OS, or third party apps you've installed.

Not that those also can't be the problem. A less than stellar developer could easily have the software you installed set up to cause notifications to pop up.

Basically, you need to look in both places. But the McAfee nonsense is nearly always from Safari notification entries.

Excellent! And, you're welcome. 🙂
