Automator app in notification centre
In Finder, go to ThisAutomatorThing.app

Right click. Show Package Contents.

Go to folder /Contents/, and open Info.plist file with a text editor. Find something like:

&lt;key&gt;CFBundleName&lt;/key&gt;
&lt;string&gt;6ARbL3D-C0D4&lt;/string&gt;


If the string is exactly the gibberish in notification, replace it with you app name.

You MIGHT need to 1) reset LaunchServices to delete the old cache and reflect the change:

/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -kill -r -domain local -domain system -domain user


AND/OR, 2) reset LaunchPad:

rm ~/Library/Application\ Support/Dock/*.db;killall Finder
