how to remove a shared computer

Simply go to System Preferences>Sharing>File sharing>Options>Uncheck "Share file and folders using SMB(Windows) ...

and yes i emptied trash.

Have you tried going to System Prefs>Network>Advanced>WINS and seeing if it is listed there, and if so, deleting (using the "-" tab)?

If you uncheck backtomymac it will remove the All tab

Actually you need to uncheck all boxes under SHARED.

In TimeMachine, unselect the Disk which has been used for Data Backup. This should be able to remove the Disk being seen on the Shared Section in Finder

Doing what jaspreeet281 suggested - then enabled it after disabling it - worked for me!

i lied - its back. it did not work 😟

This worked perfectly here, thank you

This worked for me, thanks!!!

I had the same computer showing up 10 times. Mac Pro 2,3,4,5...... I did a hard reset of my airport router and they all went away. Seems like this info is stored on the router and not the computer.

Try to reconnect to the LAN: turn WiFi off and then on (or unplug and then plug back ethernet cable).

Thanks! This solved my problem.
