macOS keyboard shortcut to dismiss notifications?

Question

I'd like to be able to dismiss and open macOS Notification Center notifications with the keyboard.

(I'm not talking about opening/closing the Notification Center itself.)

Is this possible in some manner with a tool or setting or other software?

Answer 1

You can create Automator service to run this Applescript and give it a keyboard shortcut in the System Preferences Keyboard shortcuts

This will close Alert and banners Notification

---

In Automator choose a new service

---

Add a Run Applescript Action

---

and replace it's code with:

my closeNotif()
on closeNotif()

    tell application "System Events"
        tell process "Notification Center"
            set theWindows to every window
            repeat with i from 1 to number of items in theWindows
                set this_item to item i of theWindows
                try
                    click button 1 of this_item
                on error

                    my closeNotif()
                end try
            end repeat
        end tell
    end tell

end closeNotif

---

Set the 'Service receives [no input] in [any application]'

Save the service.

---

Open the Keyboard shortcuts in System prefs and set your for your service under 'Services'

Now any newly launched app will pick the shortcut up.

(Note: I structured the script to counter throwing an error that will occur when the notifications/windows start to close.

otifications/window are numbered 1 through to the total count. But as they close the script would still be working of the old count. But the system will be re assigning the index of the windows.

So where we say start at 1 -6 the script will try and close window 1, window 2, window 3 and so on. But the system has re assigned the window numbers 1,2,3 to the last remaining windows. But the script will try and close window 4 and throw an error because it does not exist. The script will catch this and deal with it. )

If you want to click the 'Show' button on an Alert Notification. you change the button you click from 1 to 2.

click button 2 of this_item

Banner notifications do not have a button 2.

But you can just click the window.

So this code should take care of Showing.

my closeNotif()
on closeNotif()

    tell application "System Events"
        tell process "Notification Center"
            set theWindows to every window
            repeat with i from 1 to number of items in theWindows
                set this_item to item i of theWindows
                set cnt to count buttons of this_item
                try
                    if cnt > 1 then

                        click button 2 of this_item
                    else
                        click this_item
                    end if
                on error

                    closeNotif()
                end try
            end repeat
        end tell
    end tell

end closeNotif

Answer 2

Not quite what you asking for:

You could limit the time displayed for banners type with

Terminal and paste in the following

defaults write com.apple.notificationcenterui bannerTime #

with the # number sign replaced with the amount of seconds you want banner notifications to stick around, then log off and back on.

To restore original function (5 seconds) use defaults delete com.apple.notificationcenterui bannerTime

I know you said no: but you could cycle the Notification on/off with a script and assign a keyboard short cut to it. Temporarily disable Notification Center in Mountain Lion from command line?

Answer 3

The original script by markhunte works but stops after a few windows. It may be that the list of windows only includes the ones that are currently visible. When you have too many this won't close all. I added a loop outside the main loop to query the windows until we get a window count of zero. Here is the code:

my closeNotif() on closeNotif()

tell application "System Events"
    tell process "Notification Center"
        set theWindows to every window
        set nWindows to number of items in theWindows
        repeat until nWindows is 0
            repeat with i from 1 to number of items in theWindows
                set this_item to item i of theWindows
                try
                    click button 1 of this_item
                    delay 0.2
                on error

                    my closeNotif()
                end try
            end repeat
            set theWindows to every window
            set nWindows to number of items in theWindows
        end repeat
    end tell
end tell

end closeNotif

Answer 4

Closing all notification (alert/banner)

Similar to the answer by markhunte in that a bit of AppleScript is used, but the implementation is vastly improved.

Namely, unlike the script by markhunte, closes also banner notifications, doesn't crash when a notification doesn't have a close button, works even when notification center is open, works with notifications where the close button isn't the first button, detects stuck notifications, and so on...

Using an Alfred workflow

If you use Alfred, you have this workflow available: Notification dismisser. It will close all the currently displayed notifications with a shortcut or Alfred keyword. Super simple to use and works as expected.

Without using Alfred

If you don't use Alfred, you can take the main script from the workflow and (same as the answer by markhunte) using Automator save it as a "Quick Action". Then set a keyboard shortcut for it in System Preferences. Does the same as the workflow, albeit requires a bit more effort than clicking "install" as with Alfred.

Answer 5

The previously accepted answer does not work in Big Sur. This script does work.

Answer 6

An indirect approach is in System Preferences, Notifications, to set the alert style to Banners. The alerts will show briefly and then dismiss themselves.

To see the alerts again using the keyboard, in Keyboard, Shortcuts, Mission Control, assign a shortcut to Show Notification Center.
