Mac Computer Name Keeps Incrementing

Hi, I have a MacBook Pro and a Mac Mini, both on WiFi connected to an Airport Extreme. Since upgrading to Yosemite, both computers keep changing their name (as seen in Sharing under Preferences) every few hours.
For example, the name changes from "MacBook Pro" to "MacBook Pro (2)", then "MacBook Pro (3)" and so on. This is occurring for both Macs. They each have unique names and there are no other devices on the network, so I don't understand why the name keeps changing as if there is a conflict. I don't see any other error messages. I can change the name back in Settings, but it immediately increments again. Rebooting all devices does not change the behaviour. Neither Mac is connected via Ethernet, only WiFi.
Anyone else see this kind of behaviour? Any ideas how to correct?

  • MacBook Computer Name Keeps Changing

    Recently my Mac computer name keeps changing. It's the normal name, but with a number at the end that keeps incrementing. How can I stop this?
    I'm not sure if it's something to do with the fact I had a partition for the public OS X Yosemite, which I have now deleted.
    Any ideas? Thanks.

    I was having the same problem for awhile, even contacted support so they could screen share and see what I meant. 
    What I ended up doing was correcting the name and then unchecking all the boxes in Sharing.  Open up Airport Utility and reset the router (basically I changed my password only because that's the easiest way to make it update).  Go back into Sharing and recheck the sharing options that you had previously.  Viola!
    So far it's been a week now and my computer name has not changed.  Hope this helps

  • Computer names keep changing

    In the Finder side bar, the name of my computer and the name of one other computer shared in my home network keep incrementing  i.e. the same name reappears but with a digit within parenthesis
    e.g. MyComputer (6). 
    The names of the other devices (hard disks) do not change.
    Any known reason for that?
    Any suggestion on how to avoid, or reset, that ?
    Thanks

    Hi,
    Are you seeing multiple IP addresses and Mac addresses for a device listed in the device list? You can apply the following steps to fix the issue:
    Step 1: turn off each device
    Step 2: go to the device list and delete the device that is showing the multiple ip address
    Step 3: turn on each of the devices one by one and once it's showing in the device with a single ip address, add the device in the DHCP reservation list.

  • My Computer Name Keeps Changing

    I system preferences sharing where you go to set your computer name I am noticing that mine says "Rob's iMac (3)" instead of "Rob's iMac".   My network hasn't changed, haven't added or removed anything.   I am using an airport extreme.    One thing I remember is that every once in awhile I will get an odd prompt trying to connect to the wi fi related to this but I can't remember.    But the annoying thing right now is that the OS will not allow me to go back and take that "(3)" off.     Does it have anything to do with VMware and Windows 7 running on my system?     It almost seems like the airport extreme thinks there are now three iMacs on the network......... thx in advance....

    I have exactly the same problem. There is one Mac on my network, WiFi is off on the Mac, the other machines are Windows 7 computers. The renames are completely random, sometimes even after waking from sleep. It's Lion that doesn't keep track and it's annoying the **** out of me.
    My trusty Snow Leopard white iMac blew itself up (literally) two weeks ago so I was forced onto Lion. It's the worst OS X I've ever used - never had to google so often for workarounds and fixes (scrolling direction, hidden user Library, problems with Mail, keyboard mapping, the list goes on and on...)
    If Mountain Lion fixes the renaming issue it might be worth the upgrade.

  • Computer name keeps changing after Yosemite install

    My iMac keeps getting into some sort of conflict with itself that causes it to rename itself.
    It's normally "Pajundrum's iMac". A morning or two after installing Yosemite, I got a message on my iPhone that my Apple ID was being used on a new device, "Pajundrum's iMac (2)". I can go into the System Preferences->Sharing and reset the name, but if left it will keep incrementing itself.
    If I'm using the computer when it happens, I get a message stating, "Another device on the network is using your computer’s IP address."
    This is the only iMac on the network. It is only connected to the network one way (through WiFi).
    I've tried reseting my router, but that didn't seem to affect anything. Does anyone know what could be causing this, or how to resolve it?

    Regarding to this, there're two different solutions how-to fix this issue:
    Go to System Preferences -> Energy Saver. Select "Power Adapter" and then uncheck "Wake for network access".
    Go to Macintosh HD > Library > Preferences > SystemConfiguration and delete the following files:
    com.apple.airport.preferences.plist
    NetworkInterfaces.plist
    preferences.plist
    and reboot after. They'll be recreated correctly after that.

  • Computer Name Keeps Changing

    In the system preferences sharing where you go to set  "Computer name" I am noticing that mine says "iMac (3)" I have changed it back but keeps renaming the name "iMac (1),iMac (2), iMac (3) and so on,,, ".   My network hasn't changed, haven't added or removed anything. This Only happens when System goes to sleep. Any Help on this???

    I had the same problem. I solved it. I use an Apple Airport Extreme. I had connected my computer to the Airport Extreme using an ethernet cable and I also activated WiFi on my computer.  My computer kept changing names. To correct this i deactivated WiFi on my computer, connecting to the internet only through the ethernet cable attached to the Airport Extreme. No more name changing. 

  • Computer name changes incrementally (1, 2, 3...)

    Dear Apple Friends,
    I have an issue that is affecting all the Macs on my home network: 3 MacBooks (wireless) and an iMac (hardwired) connected to an Apple Airport Extreme dual-band 802.11n/a/b/g 5Ghz/2Ghz wireless router. All the Macs are running Yosemite 10.10, I am running firmware v7.6.4 on the Airport (latest version). We have turned on Back to my Mac, File Sharing, and Screen Sharing (all are used pretty regularly) in the Sharing screen.
    So here is what is happening...
    All the Macs on our network are having their computer names changed with the suffix of (1), (2), all the way to 6 now.
    I have tried resetting our Airport router (turn off/on again) and that seems to stop it for a day but then it starts again.
    A few days ago, I did a factory reset on the Airport router per the instructions on the Apple website (hold down reset until it blinks constantly) to clear the router. Sure enough, the names started changing again after about a day.
    Sometimes, I will change the name back, and it will rename itself again automatically right after I change it. i.e. John's MacBook Pro => John's MacBook Pro (1)
    I have gone so far as to reboot every Mac on the network, shutting off the router, then turning it on again, and the issue returns. I am going to try and set up a DHCP reservation next and see if that helps.
    Has anyone else run across this? If so, is this a bug or is there something I'm missing here? Thanks you for your time.

    To "fix" I:
    First, I turned off networking which was WiFi in my circumstance.
    Next, I named my computer back to the original desired name in the "Sharing" system preference without the (n).
    Then I added a "--no-namechange" parameter in the /System/Library/LaunchDaemons/com.apple.discoveryd.plist.
    Unloaded and loaded the deamon:
    sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.discoveryd.plist
    sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.discoveryd.plist
    Last, I reconnected to the network.
    Now when I connect to the network instead of getting something like below in the Console.app:
    "discoveryd: Basic Bonjour Changing computer name from <hostname> to <hostname> (2)"
    This appears in the Console.app:
    "discoveryd: Basic Bonjour Would have changed computer name from <hostname> to <hostname> (2), but it's disabled"
    I could not find a Yosemite bug filed https://bugreport.apple.com/, but this site helped me hack my solution:

  • Why does the local network and computer name keep changing?

    After upgrading to Yosemit the local network name and computername on my iMAC keep changes link:
    Mycomputer-1
    Mycomputer-2
    Mycomputer-3
    Why?
    I have tried to change it back in sharing and network locations.
    Is this also the reason the my iPhone cannot find my iPhone often cannot find my iMac when I will sync it? Then I have to restart the iPhone and iTunes on the computer. This happens very very often.
    Maybe it also linked to these errors which the log is full of - many every minute:

    I think the is some bug/clash between bonjour and other network protocols. That is only a guess.

    After resetting the computer name and local host name to the correct name without the number I also shotdown my iMac, my AppleTV, my iPhone, my iPad and then rebooted my Airport/Time capsule it seemed to work at least for several days. But yesterday I discovered that my Apple TV now also has changed name to Apple TV (2).
    I logged into iCloud.com to see my devices and here it was really wired. My Apple TV was called Apple TV (2) and my iMac also had (2) after the name. Then I checked it on the iMac but here it was correct! Why can it have one name on the iCloud and another on the computer.
    I restarted both the iMac, Apple TV and Airport Time capsule then everything was correct also on iCloud.com.
    But today the iMac was called the name (2) again on the iMac. And now the local host name also had -2 after the name. It has not always been both names that has changed. That is really wired. And today Wifi was not working on the iMac after wake from sleep. I changed the name back and rebooted again also the Airport Time capsule. Now it is working again.
    The log is still full of this messages:

    The name is not the only problem. Often itunes will not find my iPhone and iPad. Then i need to close iTunes and restart the iPhone and iPad then it works for some time.
    And the iPhone and AppleTV will not always wake the iMac from sleep. I am wondering if the is linked to the changing of name.
    I have seen by googling that it can be related to a sleep proxy problem so it seems like that here is two devices on the net with the same name that is why name is changing, but to know this do not help me to solve the problem. I have also seen all the suggestion to turn almost every services off on the computer, but again I it is not a solution and I have the iMac and devises to use the functionality not to shot everything down. So I do not really understand people saying turn off itunes, turn off blueboth, and turn off this and that.
    Apple must soon come with a real solution. We are really many people have these problem since we upgraded to Yosemite and iOS 8.
    I have also listed some of the iTunes errors from the log below:

  • My iMac's computer name keeps changing automatically after Yosemite upgrade

    This started happening once I upgraded my iMac to Yosemite. It will add numbers to the name of my iMac.
    Example: It starts off as say "My iMac"
    Then a half day later, it changes to "My iMac (2)"
    Then the next day it will be "My iMac (3)"
    And if I open the Finder window, it will show "My iMac" and "My iMac (2)" under "Shared" but if you click on them, nothing happens.
    When I go to System Preferences > Sharing the computer name will have the number there "My iMac (3)" and say it can be found as MyiMac-3.local
    If I change it back to just "My iMac", the number process starts all over again. I even tried naming the iMac something it was never named before and the same process occurs with the adding of the numbers.
    Anyone know how I can fix this?

    Have had the same issue with an iMac and MacBook Pro, both with Yosemite (MacBook upgraded from the Yosemite public beta). Both previously had Mavericks, and at one time or another would have had both Ethernet cable and Wifi on. This issue has only occurred since the upgrade to Yosemite. I do not use iCloud, so I believe that may be irrelevant and merely coincidental.
    The solution provided by an Apple Care rep seems to have resolved the issue. Has stuck now on both machines for the last few hours. Time will tell for certain, but here's what we did:
    - in System Preferences > Sharing, remove the (2) [or whatever is extra; mine was iMac (2), so I removed the (2)
    - exit Preferences
    - shutdown
    - restart machine in Recovery mode (machine off, press and hold Command + R, power on, when Apple logo appears release keys)
    - may take a few minutes to boot (depends on machine generation/speed, RAM and such)
    - open Disk Utility
    - select the OS disk (mine was Macintosh HD; selected the 'indented' item)
    - run Verify Disk Permissions
    - when finished run Repair Disk Permissions
    - restart
    On the MacBook I tried turning on Wifi and so far so good.
    Banish the deux!

  • Computer name keeps changing by integer Name (2)

    My 2011 i7 iMac running 10.7.4, regularly changes the computer name. Always when rewaking it from sleep, the "Name" becomes "Name (2)". It claims "the name is already in use on this network". And this assertion is most certainly false. A quick search informs me this issue has existed since 10.5.8; I am experiencing it on 10.7.4 so I have to assume the cause has not been investigated or not found (or both).
    Since the issue seems linked to Shared Resources I am going to try not sharing anything from this iMac from now going forward to see if this ends the behavior.
    Whats really iritating about this is that the System Preferences > Sharing panel has a Lock on it that is *supposed* lockout changes to the settings under it. But the system is bybassing that lock mark and changing something without asking. Not okay.

    I have been having the same problem ever since updating to 10.7.4.  I have read of other people having this problem too, without resolution, so I presume it to be an Apple bug that will get ironed out in the next update.
    Hope this helps

  • Computer name keeps getting (2) appended to it.

    I've searched high and low and can't seem to figure out why my iMac thinks the computer name is already being used on the network.
    I can see in the sharing preference pane that the original name is what is indicated with this copy:
    Computers on your local network can access your computer at: XXXXX.local
    However, the name in the field above it has XXXXX (2) and each time I try to get rid of the (2) I get the message:
    The name of your computer “XXXXX” is already in use on this network. The name has been changed to “XXXXX (2)”
    I can change the name using the EDIT button to anything else I want, and it doesn't add the (2). But once I change it back to my desired computer name, I get the same message that it's already being used.
    I've tried turning off all of my sharing services but that still doesn't seem to allow the name to be used.
    Any idea what other process is running that can be using the name? How do I figure out where the conflict is occurring?

    Thanks for the suggestion, Alberto. I turned all networking off and was able to make the change successfully. However, once I turned networking back on again, the same message popped up:
    The name of your computer “XXXXX” is already in use on this network. The name has been changed to “XXXXX (2)”
    In the Sharing Preference Pane, I verified that it appears to still be using the correct .local name:
    Computers on your local network can access your computer at: XXXXX.local
    But the Computer Name in the field above the message switched to XXXXX (2) again.

  • Computer name keeps changing to [myname]'s mac (2)

    I change it manually to [myname]'s mac. but few days later the "(2)" keeps appearing. I know its not a "problem", but I don't understand why that happens.

    Mine does the same thing. I have also seen others mention the issue as well.
    I think that it has to do with your iMac and your router not interfacing correctly. It seems to occur when the Mac wakes up and asks the router for an IP through DHCP and the router has not forgotten the Mac's last IP. The router tells the Mac that another device is using that name and so the Mac alters its name to obtain an IP.

  • Local network computer name keeps changing

    I haven't been able to work out why my iMac has bouts of telling me that my computer's name is already in use on the network and adding a number to it. I keep having to go into System Preferences/Sharing and change it back again so that my husband can use the shared printer. My husband has an iMac and MacBook on the same network. I also have an iPad.
    It's a wireless network with a Thomson router.
    Any ideas gratefully received!

    Margaret,
    Sounds like your computer is still registered on the network when logging in.
    Try this setting: System Preferences > Network > Click Airport on the left > click Advanced.. bottom right > Airport tab > Check "Disconnect when logging out". > click OK.
    See if that helps.

  • How do I change my computer name?

    My computer is being assigned a new name by the operating system.  A window opens stating that this computer is already being used on the network and a new name is automatically assigned.  For example, my computer name is drp-mbp and then it is assigned the name drp-mbp(1).  Why is this happening and how can I change the name back to what it was?
    Thank you.

    It would appear that you either have other devices on your network using the same Computer Name, or the system has messed up and "thinks" it has found another device with the same name. See this discussion: Computer name keeps changing.: Apple Support Communities.
    Also:
    Mac OS X will automatically increment the computer name when it thinks there are duplicate names on the local network. are your other devices also seeing all these different ghost iMacs on the network?
    what is your network setup? what/where is the main router? and how many routers do you have? is only one router doing DHCP duties?
    it's possible that your iMac is being served multiple IP addresses and therefore appears multiple times on network. alternatively you might have some static IP addresses set up that are conflicting with your DHCP setup.
    btw, the free version of IP Scanner will show you up to 6 devices. if you don't want to buy a licence, you can simply keep hitting the rescan button to try and get a different combination of devices shown: http://10base-t.com/macintosh-software/ip-scanner
    Do you have more than one router in your network?

  • Ping Computer Name

    Hello,
    I have set up a pptp vpn service on a windows 2008 server. I can successfully connect my Mac to the vpn, but when I try to ping the mac from the server using the mac computer name it fails. I have attempted various combinations of names with no success. If I connect to the vpn using a windows computer I can successfully ping the computer by name. I have spent a couple of hours reading support postings regarding this issue, but have not come up with a solution. Has anyone experienced this issue and come up with a resolution?

    Did you rerun CEICW and go to a single NIC setup?
    See:
    http://msmvps.com/blogs/kwsupport/archive/2008/09/07/uninstalling-isa-2004.aspx
    -- Al
    AMBW, I was following the instructions in that article, but errored on the final run of CEICW and was frightened into keeping the second NIC in the configuration.  I uninstalled ISA, reconfigured the cables, etc., amd rebooted.  I thought my server
    had bought the farm when it looked like the boot was hanging on Configuring the Network Connections.  I was advised to let it complete, and it did after 2 to 3 hours.  I reran CEICW, removed the second NIC from the configuration, and here I
    am.  The Information Store can't find the computer.  And that is because something still reports that the computer is still at the original IP address.  That IP address was held by the original LAN NIC, which was failing and had to be removed.
    I went into the DNS server, created a new reverse lookup zone, and added PTR records for the server, and the two client computers.  I can ping the server by name and by IP ADDR from a client computer.  But a ping of the computer name still returns
    the 10.0.0.2 IP of the original setup.  I even deleted the original reverse lookup zone folder from DNS, and presumably from AD as well.  Rebooted, but still no joy.  Where, oh where in the world is that original binding and how do I change
    it?
