Remove Non Existent Shared Device
Ok I recently bought an previously owned Macbook Pro. When I got it I found it preformatted and ready to use just had to change some account settings. I was originally going to format it myself but after not finding a large enough flash drive to put a copy of mac on I just used what was there since it was basically a fresh copy. The only thing I am having problems with is apparently the computer shop I ordered this from had a sharded mac server of some sort connected to it. Now that I own it the server says its still their but that is not true I desperately need a way to delete the server from the shared computers list on finder. I do use the shared computer features so I need to keep them enabled. I know it doesn't really matter but it is killing my OCD horribly bad.
MacBook Pro, OS X El Capitan (10.11.5)
