Hi ecarperrr,
Thank you for contacting Apple Support Communities. Based on what you stated, it seems like you want to stop receiving notifications on your Mac. It looks like you have already done some troubleshooting to solve this issue. Even though there is a chance that you've tried these steps already, I would recommend you follow every step and let us know if the issue persists.
- On your Mac, choose Apple menu
> System Preferences, then click Notifications. - In Notifications preferences, select Do Not Disturb on the left, then set options.
- When Do Not Disturb is on, the Notification Center icon in the menu bar is dimmed. You don’t see or hear notifications arrive; they are collected in Notification Center where you can view them later.
You can also turn on Do Not Disturb by holding down the Option key while you click the Notification Center icon
in the menu bar. Or click the icon to open Notification Center, swipe down, then turn on Do Not Disturb. It stays on until midnight, the next scheduled time to turn off (based on settings in Notifications preferences), or you turn it off.
- On your Mac, choose Apple menu
> System Preferences, then click Notifications. - In Notifications preferences, select the app on the left, then deselect the Allow Notifications option for the app.
- All other notification options for the app are dimmed. You no longer receive any notifications for the app."
Receive, pause, or stop notifications on Mac
Please don't hesitate to let us know if the steps resolved your issue or if you need additional assistance.
