It is a default setting that Apple News sends notifications to the Mac, splashing a steady stream alerts across the display, even onto the locked screen, and into Notification Center of macOS. If you think these frequent Apple News notification are a bit annoying and do not want them on your Mac, you can totally disable them for the News app.
1. In the upper left corner of the screen, open the Apple menu, and select “System Preferences.”
2. Select “Notifications” to access the Notification Center preferences on macOS.
3. Find “News” in the list of apps that are set to send notifications, and select “None” as the News alert style.
4. Now you may exit System Preferences as usual.
Once you choose “None” as the alert type for Apple News Notifications, you shall no longer receive any of these on macOS.
Most apps are set to push notifications as default on macOS, and so is the Apple News. Constant notifications can be very distracting if not annoying, and that is why some users have “Do Not Disturb” node on the Mac enabled constantly, to maintain focus at their workstations, maybe.
Whether you like Apple News notifications on your Mac or not is just a matter of personal preference. Some users are enjoying the frequent notifications, and choose not to disable the alerts coming from apps.
If you feel like you have to dismiss notifications on your Mac every time they pop up, you might want to enable perpetual “Do Not Disturb” mode 24/7/365 to regain some sanity. If you have no use for Notification Center at all, you might as well completely disable it and remove the menu bar item by unloading the associated kernel module. BUT that is really only appropriate for the most advanced Mac users.
