One shortcut clears every notification.
Even the ones macOS holds back. Press it from any app, with no aiming at little close buttons.
Free for 14 days with no account, on macOS 14 Sonoma or later.
What it does
Every banner and alert closes, including the ones macOS holds back after an app sends too many. A menu bar countdown shows it working.
Press Control-Option-Command-N, or a shortcut you set.
Notification Center changes with most macOS releases. Your license includes two years of updates, and the key keeps working on the last version it covers.
No account and nothing sent anywhere. The license key is checked on your Mac, offline. Needs macOS 14 Sonoma or later and Accessibility permission, which setup walks you through.
Pricing
One purchase for all your Macs, with two years of updates and no subscription.
Everything works during the trial, with no account. After it, the menu bar click still closes what is on screen; a license key adds the shortcut and the full clear.
