Uninstalling Serviio from Mac OS X properly

Hey guys,

I uninstalled Serviio quite a while ago, but have just found that the server on my Mac still shows up on my friend's smart TV when my laptop is on the network. I had already put the application files in the trash and deleted them, and have recently executed the recommended prompts found on FAQ, but the server is still running. Any other suggestions? Thanks in advance.

something similar here.

Full uninstalled console and server, rebooted, cleaned cache with CleanMyMac app, rebooted, installed Serviio 1.6.1 again but still gives me wrong CoverArt for my movies.

How can I FULL uninstall and clean my system?
