I used to have a Synology and ran CloudStation but after the Synology NAS kicked its legs in the air and died I decided that I only required a direct-attached RAID setup. Over 10 months after uninstalling all associated software I still have a link to CloudStation Notifications in my Notification Centre (2015 13" Retina MacBook Pro, 10.13.6). Any ideas how to get rid of it, please.
