how to remove a shared computer

This worked for me, on macOS Sierra:

1. Restart Bonjour

- Click Launchpad in the Dock, then Other > Terminal

- In the Terminal window, enter the following:

sudo killall -m mDNSResponder

2. Restart Finder

- Hold down ctrl+alt and click the Finder icon in the Dock

- Select "Relaunch" from the drop-down list

Try this: and then at the end physically turn computer off then on..

I've been working on removing an old HP computer and making only a little headway when I came across your suggestion and tried it. I was multi-tasking on my Macbook Pro and using my Mac and didn't want to meddle with the router physically until the Macbook Pro was finished with what I had it doing, so I decided to go ahead and try your suggestion.

The problem was this: I had an old HP computer visible on the Finder list at the left side of the window and wanted to remove it.

In a previous post, I came across the check/uncheck Bonjour computers suggestion in the Finder Preferences under the Sidebar menu and it would indeed 'hide' the HP but there was a new item which appeared with the word 'All' in it that came on in place of the HP item and I didn't want to see either.

As soon as I re-checked the Bonjour computers checkbox, the HP came back so I knew it was still present, just hidden and since I no longer use that computer, I wanted it gone for good.

Next, I saw the thread about toggling the File Share off then back on and voila! My HP is now gone off the Shared list in Finder and I can toggle Bonour computers on and off and HP is still gone. Yay! Thanks for the help wstoneburner and a few others who posted before yours which led me to your suggestion.

Try this.

In Finder, choose Go > Connect to Server… (⌘K). If any of the extinct computers show up under Favorite Servers, remove them. Then, from the Recent Servers pop-up menu, choose "Clear recent servers…". Confirm.

(It may or it may not work, but there's no harm in trying.)

This does not work. I have some PCs I used to be on a network with but no longer work at that company. They still show up in my sidebar. Have tried killing Finder prefs, sidebar prefs and even killall Finder from Terminal. Of course if I uncheck show Bonjour computers from Finder prefs they go away but so do my local macs. If I recheck show Bonjour computers they all come back including the extinct PCs. I'm on 10.6.8 but have had these showing up under 10.6.7 as well....no way I see to make them go away. And yes I logged out after each attempt.

I just setup my new MacBook, and I too had my daughters pc in the shared window. I tried to follow all advice and was not able to remove it. I did see it in Network and thought how could this show up on a new computer when I realised the information was coming from my router. So I went into the routed ip and found her in allowed connections and blocked her, restarted the laptop and now it is gone from the shared window. Maybe helpful to some.

and yes i emptied trash.

Same problem here. Extinct computers, plus one mysteriously named "MacbookPro -1085," continue to show up. I don't want to hide my actual networked Macs, so the "hide Bonjour computers" idea won't work for me. I just want to get rid of the clutter. Weird that Apple does't provide a way to do this.

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

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

If you uncheck backtomymac it will remove the All tab

Actually you need to uncheck all boxes under SHARED.
