I am trying to get rid of the GrowlMail notification. I have tried to follow instructions posted and can get into the Library to find the Mail folder but do not know how to find the /Library/Mail/Bundles/GrowlMail.mailbundle to remove the mail bundle. I am going in through the finder on OS X 10.9.3
I am a real novice so need clear steps to follow. The steps I have been trying are here: How to remove GrowlMail (on Mavericks)?
