How to remove GrowlMail (on Mavericks)? I've installed Mavericks and started to us the Mail app from Apple again, but every time I start Mail I get the message:


  Incompatible Plug-ins Disabled
  
  Mail has disabled the following plug-ins:  
  
  
    Growlmail
  




I've tried disabling and removing it in the System Preferences under Growl but the message above keeps popping up when I start Mail.

How can I remove it?
Close Mail.app

Open a Terminal and enter chflags nohidden ~/Library.

Now you can navigate with your Finder to the following directories and delete the plugin GrowlMail.mailbundle:


~/Library/Mail/Bundles/GrowlMail.mailbundle
/Library/Mail/Bundles/GrowlMail.mailbundle 


When starting Mail.app now, you shouldn't get any error messages related to GrowlMail.
