I've been trying to create a script to disable/enable the Notification Center, even if it's temporary. It should do the same as manually sliding the Notification Center, scrolling up, and toggling the "Show Alerts and Banner" badge.
Anyone knows if it's posible and how to do it? 🙂
Thanks!
That login banner is a provided aspect of the Game Center API in the iOS SDKs, as far as I'm aware there is no way as a developer to disable it from opening when the Game Center login completes. As a user, there is certainly no way to disable it, because it is part of the application's compiled source code.
However, note that it's not the banner that is causing the delays and skips. It is actually the entire login process to Game Center. My only advice is when you open a game that has Game Center logins, open it up to the first functional screen, and just wait the ~5-10 seconds it takes to reveal the Game Center banner. After the banner has displayed and disappeared, proceed normally and you should not be affected any further.
With Mavericks and later, you can do this using AppleScript's 'display notification':
display notification "Lorem ipsum dolor sit amet" with title "Title"
                          
That's it—literally that simple! No 3rd-party libraries or apps required and is completely portable for use on other systems. 10.9 notification on the top, 10.10 DP in the middle, 10.10 on the bottom.
AppleScript can be run from the shell using /usr/bin/osascript:
osascript -e 'display notification "Lorem ipsum dolor sit amet" with title "Title"'
You can also customise the alert further by adding…
a subtitle
Append 'subtitle' followed by the string or variable containing the subtitle.
display notification "message" with title "title" subtitle "subtitle"
The above example produces the following notification:
sound
Append 'sound name' followed by the name of a sound that will be played along with the notification.
display notification "message" sound name "Sound Name"
Valid sound names are the names of sounds located in…
~/Library/Sounds/System/Library/SoundsPosting notifications can be wrapped as a command-line script. The following code can be run in Terminal and will add a script to /usr/local/bin (must exist, add to $PATH) called notify.
cd /usr/local/bin && echo -e "#!/bin/bash\n/usr/bin/osascript -e \"display notification \\\"\$*\\\"\"" > notify && chmod +x notify;cd -
This is the script that the above will add to notify.
#!/bin/bash
/usr/bin/osascript -e "display notification \"$*\""
Now to display a notification:
notify Lorem ipsum dolor sit amet
sleep 5; notify Slow command finished

To disable Notification Center from the command line, write a KeepAlive key that is false into the /System/Library/LaunchAgents/com.apple.notificationcenterui.plist like so:
If you want to re-enable Notification Center, you’d just run the same with a true:

Method to ENABLE without sudo:
Then just hit Command+Shift+G and go to /System/Library/CoreServices/ then find “Notification Center” and double-click it to launch it again
