An unknown computer shows up under SHARED in Finder

An unknown computer (named "mac001b63aca152) that its info shows that it is PC Server shows up under SHARED in Finder. Is there a way I can be sure it doesn't have access to my files and also is it possible to remove it from the SHARED list?
Thanks in advance,
Behrang

I have seen a number like that "mac" followed by what looks like MAC address on my MacBook Pro in System Preferences > Network > Airport > Advanced Button > WINS tab at the Computer name.
It seemed to happen following an update where it seemed to have forgotten what I had named it and used the Airport Media Access Card (MAC) address instead.

Network devices not showing up under "shared" in finder bar

Ok so i have a network that consists of a maxtor nas device, 2 win xp pc's, 1 win7 pc, d-link 524 router, and my macbook pro. I would like to be able to transfer files between my mac and the devices and use the printer attached to my maxtor. My issue is that none of the computers show up under the "shared" section of finder or under network. I use to have this issue with leopard but it resolved itself. Now under snow leopard for a couple months and i have yet to get it work. I can access my mac and other pcs from a pc. Anyone know how to get my network to show up on my mac?

Your problem is very common under Snow. At first my shares did not show up under shared in finder windows. I, then, of course, used "Connect to Server" to connect to the shares--both Mac and PC. I found that the more I kept the shares active the more likely they were show up under shared. Then, I discovered that if I kept the computers from sleeping during the period of needed access they would tend to stay in shared without nearly so much keeping the connections active.
If you do not like the above work around, then there are two other possibilities. You can elect to show mounted items on your desktop. Do that and connect to each share. Then, go > users > unlock > + login options > try dragging the mounted shares to the login item window. If successful, then the shares should be available at login.
Another approach is to mount and connect as indicated above. Then, making an alias to the share should at least make things faster.

Two unknown computers show up under "shared." What does this mean?

When I open a finder window, two computers that are unknown to me show up under "shared." What does this mean?
Does this mean someone has broken into my wireless network? Or that these people have access to my files? I don't want to be "sharing" anything with people I don't even know.

It means two of your neighbors also have a wireless network. They cannot access your computer unless you give them your userid and password.
Go ahead and try to access their computers. Unless they have guest sharing turned on, usually to share photos with family and friends, you will not be able to access their computers.
I’m on a university network and have hundreds of names in the Shared section of my sidebar, but do not have access to their computers, nor theirs to mine.

Mystery computer shows up under Shared list in Finder

I’m hoping someone can help me solve a mystery…I have 2 macs (a late 2008 MBP and the most recent white MB), both connected wirelessly to a Time Capsule. From time to time, I see a computer show up under the list of Shared devices that I cannot identify. It is listed just as a MAC address and looking at Get Info tells me it’s a PC server. I have no other computers or devices connected to my network. and I also have the network protected with a password. I even changed the network password this morning, and the mystery computer still appears and disappears at random. When it does appear, I can connect to it as a Guest, but there are no folders or other content available.
Can anyone suggest what might be going on? I’m concerned that my network is compromised and that someone else has access to my files. Should I be worried and how can I fix this?
Thank you!

It's more likely that you are seeing someone elses computer that may have sharing enabled. If you are in an apartment building or have neighbors otherwise close-by, you may just be picking up their machine. Because you see theirs does not mean that they can access yours in anyway. HOWEVER... if you see a machine appear under your shares (or otherwise) that you are not familiar with, you should NOT attempt to connect to it. Doing so could potentially compromise your system. It's not very likely... even less likely on a Mac... but it is something to avoid.

Printer attached to wifi AP shows up under 'Shared' in Finder; can't print

I have reviewed quite a few threads on Bonjour printing problems cropping up in the move from 10.4 to 10.5. I still can't seem to get mine to work.
I printed fine to my printer (connected to wireless AP) under Tiger, but can't even do an 'Add Printer' for it after upgrading to Leopard.
Oddly, my printer's Node Name shows up in the Finder under 'Shared'. So it seems that my mac sees the printer. The entire network consists of the mac, wireless AP, and printer.
Any other ideas? Thanks!

Let me suggest going to this thread on the Airport printing discussion.
I found two issues:
1) HP's having problems with file permissions. Run *Disk Repair* first, then download and run the *newest HP printer drivers*.
2) Apple seems to have introduced something called CUPs. It's new to me and every computer I have that runs on Leopard or was recently upgraded to Leopard has very confusing printing problem, directly connected or wirelessly connected.
The thread above is helpful, but somewhere, I need to learn more about CUPS.
Try putting *http://localhost:631/* in your browser!
As soon as I figure it out, I'll let you know.
I also changed my USB cables to *USB2 cables*. Suddenly, it seems to matter!?

Unknown computers showing up under "Shared" on secured wireless network.

After reading through the forums, it looks like I am not the only person who has encountered this, but I haven't found any real answers and my situation is a bit different.
Yesterday, unknown computers started showing up in the "Shared" sidebar in Finder. This happened both on my MacBook Pro and my iMac. I have a password protected wirelss network. I know these are other people's computers and not just printers or peripheral accessories on my wireless network because they have names like "John Doe's Mac Mini" and "Smith-pc."
I understand that this doesn't mean that someone is trying to hack into my computer, that they could just have sharing enabled on their computer and it is broadcasting its availability for a connection. However, I don't understand how these computers are broadcasting it. I live on a farm in an isolated area where it is not possible for someone else to be picking up the signal from my wireless router. I think I have established that these are Bonjour connections because I can make them disappear from the sidebar by unselecting "Bonjour Computers" in Finder Preferences. I have checked all of the MAC addresses that my wireless router (Apple AirPort) says are connected and I can account for all of them.
My ISP comes in through a wireless antenna system. Is it possible that they suddenly changed something yesterday that is letting Bonjour signals from other subscribers to be broadcast through their network? I have used this ISP for a couple of years now and this just suddenly started yesterday.
Should I be concerned? I have gone through and made sure that file sharing is not selected on our computers. I'm not sure what precautions I would need to make with our iPads, iPods, etc. Is the appearance of these computers simply an annoyance, or am I in any way at risk?
I would appreciate any insight anyone can give.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

TS2972 Apple TV (2) works great with everything BUT iTunes on my computer, AND I can turn Home Sharing Off and On multiple times and NOTHING show up under "shared" and NOTHING shows up under Computers on Apple TV???

My Apple TV (2) works fine with my iPad and iPhone.
My iTunes syncs with my iPad and iPhone.
I have turned "Home Sharing" off and on multiple times - of course using the same AppleID - and NOTHING shows up under Shared (and then Shared goes away) and NOTHING shows up under "Computers" on Apple TV?
Why aren't Apple TV and iTunes smart enought to work with each other on the same network? This should not be this difficult...

I think I am having the same problem.
My issue: since updating the software on ATV, I get an issue where shortly after starting a movie or video of some sort streaming from iTunes on my iMac the vid stops and Apple TV tells me that I need to connect to my Home Sharing account. Sometimes I can fix it by turning Home Sharing off and back on in my settings. Sometimes I need to completely reboot the AppleTV!
Any suggestions???

A stranger is showing up under "Shared" in my network

A stranger is showing up under "Shared" in my network. "Frank's Macbook Pro." I don't know anyone named Frank and my internet connection (comcast) is secured. I looked under "preferences/sharing" and didn't find a way to "Frank's Macbook Pro" from showing up. Advice? I'm a newbie. Please explain simply. Amy

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) at the request of a stranger. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
7. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
8. If you see an error message in the Terminal window such as "syntax error," enter
exec bash
and press return. Then paste the script again.
9. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
10. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
11. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At or near the top of the results, there will be a line that begins with "System Version." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.
Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

Unknown computer shows up in Finder, am I hacked?

H - got home tonight and notice a new Mac Book Pro icon under Shared in Finder. It is named "Lupin3d's Mac Book Pro" and it is "Not Connected". I don't see any option to connect to it.
I have a Mac Pro tower named "Mac" and I am certain no Mac Book Pro laptop has ever knowingly been on my network. There is a Windows machine also on the network but not named like that.
We live in an apartment building so this could be a Mac Book Pro in some other apartment in the building. We have wireless which has WEP enabled and a very long gibberish password.
My Mac Pro has bluetooth enabled for the mouse. I did not have Firewall enabled on my Mac Pro as we sit behind router NAT firewall so didn't think it was needed.
How is it possible this foreign MBP appears in my Shared list under my Finder window?
Am I compromised? Should I be concerned? I don't see how this Lupin3d MBP could possibly be on my machine unless it had gained access to my local network (having hacked WEP on the router?) which just seems really unlikely. Is there some easier way one Mac can connect to another without being on the same local network?
This is my first Mac, so please forgive the newbie questions, I'm not entirely familiar with attach vectors in Mac world. All advice gratefully received. thanks!

hi KT
thank you very much for replying
I ran who and it just shows my user name logged in twice (once for console, about the time i rebooted last yesterday, and once just now when i fired up Terminal). However I checked iTunes and yes, I have it set to Look for Shared Libraries. Do you think perhaps that is why I can see this unknown machine?
If it is iTunes, I'm still curious to know how my Mac can see the other Mac, when there is no network in common?
thanks again for your reply, i appreciate it

How does another computer show up as "shared" in my file sidebar?

how does another computer show up as "shared" in my file sidebar?

If you are seeing someone else's computer in your sidebar it is because they have 'shared' something on their computer and hence made it available to you. If you share something on your computer then your computer would become visible in their sidebar.
You can access their shared computer without them being able to access yours. They do not have to do anything on your computer to make theirs available to you. All they have to do is tell you what username and password to use to access their computer.

MacBook shows up multiple times under 'Shared' in finder

My MacBook keeps showing up multiple times under 'Shared' in the Finder sidebar. All sharing services are turned of in System Preferences. The number in the computer name is automatically added. When I change the computer name to another name, all existing 'ghost computers' stay there in the sidebar. How do I get rid of these?

Known bug. Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.
Feedback
Or you can use your Apple ID to register with this site and go the Apple BugReporter. Supposedly you will get an answer if you submit feedback.
Feedback via Apple Developer
Some people have managed to stop this behavior by going to System Preferences/Sharing and stopping all sharing except screen sharing.

Multiple macs showing under Shared in Finder

Hi,
Running Yosemite 10.10 on an iMac 27".
Noticed that I have 19 Pete's iMac (#) showing under Shared in the Finder as per screen shot below. I recall this happening a few OS X versions ago but what's the cause. Is it anything to do with my ISP assigning and changing IP addresses regularly?
Does this matter at all.
All thoughts appreciated.
Pete

I had the same problem on my home network with my MacBook Pro (Retina, Mid 2012).
My home network has an Airport express attached to the cable modem creating the wireless network and an Airport extreme on the other end of the house extending the network. On the network are two Apple TVs, an iMac, my MacBook Pro, a TIVO, and 3 iPhones.
For me the solution involved two steps: first, turning off "Wake for Wi-Fi network access" and "enable Power Nap when plugged into a power adapter" under the Power Adapter Tab of Energy Saver in System Preferences. Next I turned off all the computers on the network, unplugged each Apple TV, and unplugged the airports. I turned back on the airports followed by the Apple TVs and then the computers.
The downside is that back to my mac and find my mac will not work when the macbook is asleep in this configuration.
I worked with Apple support and the case was escalated. They called me back to tell me there was not a fix.
Initially we had turned off "Wake for Wi-Fi network access" and restarted the Airport Express and that made the MacBook Pro stop renaming itself and eliminated all but one of the phantom computers under Shared in the Finder side bar (number 9). But, the remaining phantom computer was driving me nuts.
I found a thread on Reddit that noted:
The problem is because of a bug between Yosemite and sleep servers. These servers reside in Apple TVs and Airports and act as a proxy for a sleeping machine on Wi-Fi. For now the only fix seems to be:
System Preferences --> Energy Saver, and UNTICK "Wake for network access".
Shut down your computer and then cycle the power on your Apple TV/s and/or Airport/s.
Power-up your computer, System Preferences --> Sharing, and rename the "Computer Name" as you wish.
This step is what killed my last phantom computer on the network.
There is an Apple support community thread that details a fix in terminal that will allow wake for network access, but I've not tried that yet. Here is that thread - Yosemite is renaming my computer - why?
Here is the Reddit thread that helped me identify that devices on the network were creating one of the phantom computers - http://www.reddit.com/r/osx/comments/2hxhp9/yosemite_computer_name_changing_for_ some_reason/
And this support community thread was also helpful - Computer name changes incrementally (1, 2, 3...)

MacBook Pro shows up twice under Shared in finder sidebar once as PC

This just started today. I have my iMac and MacBook Pro networked through Airport Extreme. Today my MacBook Pro shows up twice under my iMac finder sidebar. First icon is itself (MacBook), second icon is PC. Both with the same name. Get info shows the second icon as PC Server. I cannot connect to the PC icon, which I'm assuming is a good thing.
Why would this suddenly happen, and how do I get rid of it? I've restarted airport, repaired permissions on both machines. Checked to be sure that only AFP is check under File Sharing on both. Network preference pane WINS shows no servers connected on Airport or Ethernet, etc.
Anyone?
Appreciate any help with this. I'm definitely not a networking expert

Ok, ive had this problem for ages and i think ive pretty much figured it out, your computer is showing your macbook over your network and through Bonjour (apples own wireless connection) Still not sure why it always shows it as a PC though, or as a server...
Anyway, I ive found where it originated from, if you go to System Preferences>Sharing, at the top you will see your computers name and underneath it will say "Computers on your local network can access your computer at:" and its name will be whatever the 'PC server' is called on your finder sidebar, in your case "tosha". You can test it by changing the name to something like "tosha1" by clicking the edit button, in may cases the extra shared computer will disappear, but, after a while it will reappear and will now have the new name. =[
Sadly I dont know how to stop this but I suggest you take screenshots and go to an apple store, tell them about the problem and hopefully they will have an answer for you, they know everything! And even if they dont, check their machines to see if they have the problem, and if they dont, look at the settings and try and find why.
Im sorry I cant be of much help but im getting closer to the bottom of this and im sure its linked to bonjour! Ill keep you posted if anything else happens!
p.s. Im not a networking expert either! Im just as stumped as everyone else!

Automatically list NFS shares under SHARED in Finder

Hi, I created an Automator workflow to mount NFS shares from a linux server. After executing the skript, the shares will be listed under SHARED in the Finder. Is there a way to automatically detect the NFS shares on the server to list it in the Finder without executing the Automator skript on every startup?

It should be possible to do so using an [Avahi service|http://en.gentoo-wiki.com/wiki/Avahi#NFS]. I'm using a similar service for my [netatalk/AFP share to show up in Finder|http://www.disgruntled-dutch.com/2007/general/how-to-get-your-linux-base d-afp-server-to-show-up-correctly-in-leopards-new-finder]. It says in the article that this doesn't work 10.5 onwards but links to an article with a [workaround|http://www.macosxhints.com/article.php?story=20071116042238744]. I hope that this will be helpful.

Unfamiliar device under "SHARED" in finder

When I opened finder today there is an unfamiliar PC server listed under shared. I don't know what it is or how to get rid of it.

I have had the same thing happen to me today. I have a Time Capsule wireless network, attached to a local service provider's cable (new yesterday) for internet service. When I "get info" on the unfamiliar device, it tells me it is a PC Server, but nothing else. it is named "your-1a4d29f243" How do I get rid of it? And how did it get on my network? I use passwords to connect my other devices.
