The answer to a previous question (that I share) suggested going to this file ~/Library/Containers/com.apple.mail/Data/Library/Preferences. How does one find that. I don't know what ~/ references and the Library files that I find on my hard drive do not have a Container subfile
If you hold down the Option key, your Library folder (
~/Library), which is normally hidden, will show up under the Finders Go menu. Just selected it (Go -> Library) and you will be there in the Finder.
Simply copy that information,
then in Finder window use the "Go" tab
then paste the
in to the pop up window and it will bring you to that place.
There are 2 Library locations on your drive.
One is the User Library, the other is the System Library
