In System Preferences/Notifications, I have 2 instances of Cocktail. I have uninstalled Cocktail and 1 instance will be deleted and the other remains. Upon reinstalling, the second copy reappears. I have also done a search with EasyFind to locate all Cocktail leftovers, but my quest has been unsuccessful. After a prolonged discussion with Apple Support, the advice (from a level 2 tech) was to wipe the drive and then do a clean reinstall. Of course, I am reluctant to that. I wonder (guess) if the problem is with Notifications and not with Cocktail. If it were in Notifications, where do you suppose it might be? Indeed I am perplexed. It seems to me there should be a file listing all the apps/files in Notifications. If so, might this be editable? AFAIK, there are no resulting problems re this issue, but I do find it frustrating that removing an item from Notifications should be so bloody difficult. All thoughs/suggestions most welcome.
