I see that you're getting popup notifications on your MacBook Pro. I'm happy to help.

How to block pop-ups in Safari

If you might have installed adware or other unwanted software on your Mac

If you see pop-ups on your Mac that just won’t go away, you might have inadvertently downloaded and installed adware (advertising-supported software) or other unwanted software. Certain third-party download sites might include programs that you don’t want with the software that you install.

If you think that you might have malware or adware on your Mac, update to the latest version of macOS. If your Mac is already running the latest version, restart it. macOS includes a built-in tool that removes known malware when you restart your Mac.

Check your Applications folder to see if you have any apps that you didn’t expect and uninstall them. If you continue to see advertising or other unwanted programs on your Mac, contact Apple.

Take care!
