I have some rules set up for Alfred workflows. This folder is located in the package ~/Library/Application Support/Alfred 2/Alfred.alfredpreferences
Alfred has just been upgraded to version 3, so I went to add a new watch folder for Alfred 3 and then to copy the rules to the new folder, but Alfred.preferences is greyed out so I cannot select the workflow folder. I must have been able to do this at one time (probably 2 or 3 years ago), but at the moment I'm lost. The Finder lets me open the package and the workflow folder.
