To stop Safari’s website notification permission prompts, open Safari > Settings > Websites > Notifications and turn off Allow websites to ask for permission to send notifications. Safari says it will no longer ask when you visit a site that wants to send notifications. If you already allowed a site and want to stop its alerts, change that site’s permission in Safari or turn off its notifications in macOS System Settings; those are separate controls. Apple’s Safari notification guide

Turn off future notification requests

  1. Open Safari on your Mac.
  2. From the menu bar, choose Safari > Settings.
  3. Select Websites, then Notifications in the sidebar.
  4. Deselect Allow websites to ask for permission to send notifications.

This is the setting that addresses repeated permission requests. It changes Safari’s behavior for sites seeking permission; it does not switch off notifications for apps or all Mac alerts. Apple documents the same setting in its Safari Websites settings guide. Menu labels and layout can vary a little between macOS versions, but look for the Notifications section under Safari’s Websites settings.

Deny permission for a particular website

If a site has already asked and you want to block it specifically, return to Safari > Settings > Websites > Notifications. Find the site in the list and set its permission to Deny, if shown. Apple defines Deny as preventing that site from sending notifications. This is useful when you want to keep permission requests available for other sites while blocking one site.

You can also use the general “Allow websites to ask…” checkbox together with per-site settings: turn off future requests and deny sites that already have permission. Safari’s Websites settings list sites whose behavior you customized, and offers a Remove control for entries. Removing a customized entry clears that site-specific setting; it is not the same as choosing Deny. If your goal is to keep a site from sending notifications, use Deny rather than relying on removal. Apple explains the site-specific controls here.

Stop notifications from a site you already allowed

The request toggle prevents future permission prompts, but a site you previously allowed may still send notifications. To stop those alerts, choose Apple menu > System Settings > Notifications, find the website under Application Notifications, and turn off Allow Notifications. Apple notes that the website remains listed there after notifications are disabled. To remove it from the Notifications list, deny its permission in Safari’s Websites settings. Apple’s guide to customizing website notifications describes both controls.

This distinction helps diagnose what you are seeing: a dialog asking whether a site may send notifications is a Safari permission request; a banner or alert from a previously allowed site is a notification. System Settings controls whether the site’s alerts are delivered, while Safari’s Websites settings control whether the site has permission and whether Safari asks new sites.

If the prompt keeps appearing

Check that you changed the setting in Safari itself, under Websites > Notifications, rather than only changing macOS notification delivery. Then revisit the page that produced the prompt. For an individual site, inspect its permission in the same Notifications list and choose Deny if available. Apple documents these settings as distinct and provides no separate command in the cited guides for globally dismissing notification prompts outside Safari’s Websites settings.

Safari also supports web apps—websites saved as standalone apps. If the request comes from a web app rather than a Safari tab, its notifications may be managed as that app in System Settings > Notifications. Apple says web app notifications require responding to the website’s permission request in the web app; the app then appears in Notifications settings. Apple’s web app notification instructions cover that case.
