What is the "Shared" section in Finder? Can the PC listed there access my MacBook?

There is a "Shared" section in Finder with a PC listed in it.  Specifically, it's a notebook computer that shares my WiFi.  Why is that PC there? Can someone using that PC access my MacBook? Do I need to set up some password security? Or can I just get rid of that apparent connection?

The PC is listed because it has its file sharing turned on and is connected to your network.
File sharing on your Mac is controlled with System Preferences > Sharing.
To turn file sharing on/off, first unlock the pane by clicking on lock icon and entering your admin password.  Then you can check or un-check File Sharing.  When File Sharing is selected from the Service list you can add or remove folders to share and edit permissions to those folders.  Click on the (?) button for more info.
Always remember to relock the pane when you are finished.

  • TS5437 Should a computer list itself in the Shared section in finder?

    I turned on File Sharing and Screen Sharing on both my iMac and MacBook to enable "Back to My Mac." However, my iMac will list itself in the shared section in Finder, but my MacBook doesn't list itself in its Finder.

    So I use this from home, so I just have my computer running to my AirPort Extreme, then to my modem from the DSL company.
    Does that mean I changed some setting in my Network system preference to cause this to appear?
    Is there anything it is used for? Can I connect do it and do anything?
    Can I remove it somehow?
    Thanks again-

  • Mac Pro keeps duplicating itself in Shared section of Finder

    My computer has recently started duplicating itself in the Shared section of Finder. It's listing up to five separate versions of itself in there. When I open Photoshop it's saying it used to be installed in a different location and needs to be repaired. I presume this is because the computer name is being updated in Sharing.
    This has happened since switching from an Airport Extreme router to an Asus one and then back again.
    I have tried resetting the Airport Extreme to default and setting it up as new. It's connected via ethernet and wifi to the computer, but the problem is happening even with wifi switched off.
    I also trashed com.apple.airport.airportutility.plist and restarted. It seems to still be happening. I've also been getting intermittent messages about my IP address being already used and it changes it. It was up to about 21 before I reset.
    I've read elsewhere that this was a bug, but everything is up-to-date, so I don't know.

    My computer has recently started duplicating itself in the Shared section of Finder.
    Unfortunately, this one of several nagging networking bugs in Yosemite for which Apple has not yet been able to offer a "fix".
    The best that you can do in the meantime is open the Sharing folder and edit the name of the Mac to the correct setting. Restart the Mac after you do this.
    It would also be a good idea to reset the AirPort Extreme back to factory default settings and then set it up again if you can. There is no assurance that this will solve your issue, but it will not hurt to do this.
    Some users have reported that reinstalling the Yosemite operating system has helped, but again this is a lot of work, with no guarantee that things will improve.
    You may have better luck posting in the Yosemite forum, since the issue that you are reporting is really more of an operating system problem than an AirPort problem. The link is just below if you want to give that a try. Good luck.

  • I have a "hacker" PC showing up under the "Shared" section of the Finder

    Today I noticed a PC computer icon showing up under the "Shared" section of the finder. The computer name was brn_921bc1. I immediately went into System Preferences and turned off file sharing. Is it really that easy for a PC hacker to come into my computer? Please help, as this seems to be a huge security threat.
    Thanks!!

    I doubt this is a hacker but you do seem to have an insecure setup. If you have your computer connected directly to a cable modem then you are essentially on a shared subnet with lots of other people Most of them aren't hackers -- probably none of them are. But this situation does leave you vulnerable which is why many people prefer to place a router in between their cable modem and their computer even if they are only connecting a single mac or pc to the internet.
    My first suggestion is that you turn on your Mac's firewall immediately. Open your System Preferences and type "firewall" in the search box. Hit return. When the firewall screen opens select "Allow only essential services". You should do this before you finish reading this thread.
    My next suggestion is to buy what's called a NAT router and stick it in between your cable modem and your mac as soon as practical. This will give you a far more secure setup than you can get with a software firewall alone. If you need help setting it up, come back here and I'm sure you can find the advice you need.

  • In my Finder window the Shared Section is missing

    Mac Pro 2007
    Processor  2 x 3 GHz Dual-Core Intel Xeon
    Memory  6 GB 667 MHz DDR2 FB-DIMM
    Mac Lion OS X 10.7.5
    In my Finder window the Shared Section is missing. Its even checked under Finder>Preferences>Sidebar. Do I need to edit something in my Library. If so, what file? in what folder? I rebooted, reset, etc to no avial.
    Thanks

    Please read this whole message before doing anything.
    This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
    Step 1
    The purpose of this step is to determine whether the problem is localized to your user account.
    Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
    While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
    Test while logged in as Guest. Same problem?
    After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
    *Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
    Step 2
    The purpose of this step is to determine whether the problem is caused by third-party system modifications that load 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.
    Please take this step regardless of the results of Step 1.
    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 log in 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 Steps 1 and 2.

  • My new computer is authorized and home sharing is turned on for both computers, but the Shared section is no longer showing up on either computer. What do I do now?

    I am not sure how to view the Shared section on either computer. It says the new computer will open it once it finds my other computer, or something like that, and I do not know why it is not finding it. Basically, I do not know what to do at this point.

    If you have the horizontal menu bar showing (File, Edit, View,...), select View, then select Show Sidebar. 
    If the menu bar is not showing, dorp down the menu in the very upper left corner and select show menu bar, then follow steps above.
    Hope that helps.  Good luck.

  • Shared Section in Finder

    Greetings: I have two computers sitting side by side (Macbook Pro and a PC Laptop). Sometimes the Laptop shows up in the Shared Section of the Finder and I can access files from it perfectly - and then sometimes (like now) it just mysteriously disappears.
    All permissions are set as when it does pop up it works perfectly.
    Any ideas on how to force the Finder to see the Laptop?
    Thanks,
    AK

    Update - I just closed Internet Explorer on the PC and the Laptop popped up in the Finder!
    Is it possible that outgoing traffic from the PC would affect the communication between the 2 computers??
    Thx

  • I do not see my iphone 42 in the device section of finder on macbook pro

    I have the latest itunes 11, OSX 10.7.5 not on mountian lion. I cannot get my iPhone 4s to show up in the device section of Finder on my macbook pre 13". I was working just fine before I installed the new itunes and now it is no longer working. I looked at the forum and could not find an answer so I am posting the question here if anyone can help it would be great.

    The iPhone will not show up in Finder, and never has. It will appear as a digital camera if there are photos in the Camera Roll, and it will appear in iTunes.

  • Unknown names under the shared section on my itunes, help!

    Yesteday i opened my itunes and i found three unknown account names like "Sam's itunes" under the shared section and when i clicked them it could listen to all of their music. I thought restarting my computer would help but i didnt do anything. Today when i opened my itunes more names appear and when i try to dissconnect it doesnt work. Why is this happening and how do i stop it? im scared people are able to get my information. Btw i live in a dorm at school, so im not sure if this is affecting it or not.
    Thank you!

    You are seeing libraries your neighbors have made available for sharing on your local WiFi network. If you don't want to see them, go to the iTunes menu > Preferences > General and uncheck "Shared libraries".  To share your own library, select iTunes > Preferences > Sharing.  It should be off unless you have turned it on.  You can share your whole library or just certain playlists.  You can share it openly or require a password.  Give the password to those you want to share with.  Note that sharing is not the sasme as home sharing.  While your computer is on and iTunes is open, others in your network can play your shared items, but can’t import shared items into their libraries.
    Go to the iTunes Help menu and type sharing in the search box if you want more details.

  • If someone finds an iphone and its being tracked...then if such person restores it and takes the previous icloud account off, can the phone still be tracked?

    In what regard? Restrictions would not impede in iCloud. All they do are allow certain changes (like age-appropriate content on App Store to be changed), and to prevent some apps from being shown on the device if they aren't going to be used, for example, I have restrictions active on my iPhone with the Youtube App turned off so it doesn't show on my home screen, and youtube links don't open into it (i find the application clunky and prefer the website).
    If the device is restored; Anything put in place by restrictions and the prior user are renderred null as the settings get completely erased.

    Was your wife logged into the libray at the time you tried to log in? I have had a similar problem and it was because another user was logged into the library when I attempted to. I got the permission denied banner.

    I am experiencing Mavericks failing to copy subdirectories from usb sticks, I am backing up game saves from a console. Both sticks I use are fine, same permissions of course since the console wrote the files. Sometimes it copies, sometimes it doesn't. It seems to be related to the mounting process.
    Thank God Apple hasn't (yet) broken bash.
