IMac shows up 10 times on my network

Hello,
I updated to OS X Yosemite yesterday(and I love it), but I have been plagued with an issue. Recently, another mac on our network tried to view my iMac's screen using the built in screen sharing, but it failed. Upon further inspection, we found that it was not the Screen Sharing program's error, but my mac had shown up on the network about 10 times. I even see my mac 8 times in my own network menu:
And see it as "[Name] iMac i3 (10):
I'm sorry I can't provide any more information, but we already tried reasigning the IPs with no avail. Any ideas?

I would like to use time Machine to back up to a network SMB drive. I can see the drive on my desktop but it will not show in the time machine window to be able to select it

I currently have a mini server (OSX10.8.5, server 2.2.2) that I am using Time Machine to back up 4 external drives that are connected to the server via firewire 800. I would like to use Time Machine to back up to a windows network SMB drive. I can see the drive on my desktop but it will not show in the time machine window to be able to select it for use.
Can this be done
Thanks for any and all help

The supported targets for Time Machine backups are local (direct-connected) disks, and network targets include Time Capsule, a disk hanging off the current-generation AirPort (though not earlier AirPort devices), and OS X Server systems.
The Time Machine storage is based on the HFS+ file system, so I would not expect TM to work with SMB file services.
While there are hacks to allow Time Machine to access network drives, I would not consider those to be reliable. Skim the forum and the 'net for related details, and for previous discussions of setting this up and the related issues that can arise.
Remember to test the recovery with whatever you decide to use; whole point of backups is the ability to restore the data, after all.
If you want to learn more about Time Machine, Pondini is an excellent resource.

Why does my iMac appear many times in my network and labelled 1,2,3, etc

why does my iMac appear many times in my network and labelled 1,2,3, etc

Ok, I solved it.
I followed this steps:
1- Turn Off Wi-Fi from the Wireless menu item
2- From the OS X Finder, hit Command+Shift+G and enter the following path:
/Library/Preferences/SystemConfiguration/
3- Within this folder locate and select the following files:
com.apple.airport.preferences.plist
 com.apple.network.identification.plist
com.apple.wifi.message-tracer.plist 
NetworkInterfaces.plist 
preferences.plist
4- Move all of these files into a folder on your Desktop called ‘wifi backups’ or something similar – we’re backing these up just in case you break something but if you regularly backup your Mac you can just delete the files instead since you could restore from Time Machine if needed.
5- Reboot the Mac
6- Turn ON WI-Fi from the wireless network menu again

When starting up a Mountain Lion iMac, it takes along time before network logins are available.

When starting up a Mountain Lion iMac, it takes along time before network logins are available. There seems to be a huge delay getting the network up and running, and I'm not sure why. This isn't an issue for identical iMacs running Snow Leopard.
If I login with a local account, I see the ethernet registered as disconnected for at least a minute, then it pops up. If I switch to Snow Leopard, using the exact same hardware, network cable, jack, etc, it's instant.
Has anybody encountered anything similar?

No. I have a rMBP and a Mac Mini on a home LAN. The Mac Mini is connected via ethernet and the rMBP is WiFi. Both connect instantly to my network. Both are running OS X Mountain Lion 10.8.2.

Try to reset Network setting thru (Setting/General/Reset/Reset Network Setting - after clicking on it the phone will ask to reboot)
According to my R&D I have experienced that one must reset the network each time when we r at home or in office or other places, the phone after resetting the network setting acquires the area specific network setting n works well, try it & if any other solution do let me known
Calling up customer care did not help me, they do keep us in a loop with the same old answeres that “Our technical team is working on it & WILL GET BACK TO u” leaving us with no solution at the end
Try what I suggest think to will help u

I have been having issues with my iCloud email on my iMac. For some time period, everyday, it won't reload and often shows symbols instead of letters for the text. Any ideas how to solve?

All I can suggest is that you open that file on the MBA and save it as a new file, then see if you can open the new one on the iMac.

How do I turn off sharing? My iMac is listed 8 times/

Hi
This just started recently. my iMac is listed 8 times under sharing in the finder. I don't know what happened but it's starting to cause problems.
The only things that have changed recently is I upgraded to Yosemite but that was working fine. I just bought a new iPad but that connects through iTunes. I never clicked to share anything.
At home here we have 6 computers. 1 PC is my son's, one PC Laptop is my wife's. Both of those are only connected to WiFi for the internet. In my office I have my main iMac for internet and daily work, my Mac Pro which I only boot when I'm doing video work, my Mac Book Pro which I use rarely now that I don't shoot video in the field and 1 old HP. These are all connect to my network Hard Wired to my Airport Extreme plus a wireless Canon Printer. When any or all of these in my office are up and running I see them in the Finder (NOT under Sharing) and I can swap files between them.
Here's a screen-shot of my finder window.
I have to get rid of all those duplicate "ghost" version of my iMac.
Thanks for your help.

GOT IT FIXED! WOW!
I did better than filing a bug report. I went to Apple support, chose chat support. When it wanted $15 or was it $19 I filed an exemption which was a choice on the page, based on the fact that I recently upgraded to Yosemite.
Got the chat fellow and here we go!!!! ;-) First off he sent me this app so he could see my screen. Then he had me do a few things like move the system configuration folder to the desktop and repair permissions. Then he had me reset the SMC and Pram. Nothing helped, all the ghost computers still showed in the finder.
As a last resort he had me reset my Apple Airport Extreme. Wala! Ghost Computers GONE! He said it was a combination of stuff but mainly it was the airport extreme when I installed Yosemite. Something to do with my network. We'll see if it holds or if the problem comes back but as of now there's no more ghost computers in the sharing part of the finder.
Thanks to all who offered suggestions. I hope maybe this helps someone else.

IMac shows it is connected, but internet / airdrop don't work

This problem started to occur since yesterday. And I have no clue why. The only thing that I have been doing (all week) is writing an essay on my iMac. I do know it installed the latest OS X update recently (Mavericks 10.9.5). Anyway, this is how the problem goes:
My iMac shows that it is connected (the wifi bar at the top is full, it shows that it is connected to my home netwerk). However, when I try to browse the internet the connection keeps timing out. Even when I try to send a document through AirDrop over WiFi (to my MacBook Air) it wouldn't work. Sometimes it will send documents up to 5 or 25 percent, but then the connection times out again and it'll stop. Mind you: Yes the connection (apparently) times out, but the wifi bar at the top of my screen still shows full connection. It helps when I reboot my iMac, I then have another full 1 or 2 minutes to browse before it times out again....
I don't believe it's a problem with my home network, since my MacBook Air still connects to the internet. I also tried the Wireless Diagnostic tool, but it would say I'm all fine since there is an internet connection. What to do... What to do...?

Hey there Modyg,
From the information in your post, it seems like you may be experiencing a software issue that is affecting your connections on your iMac. Here is an article that can outline for you some basic software troubleshooting to help you address this issue:

I'm suddenly getting the kernel panic message and constant restarts when connected to the time machine wireless network. if is switch to the BT network, all fine. no help found so far as to what's wrong or how to correct, anyone have any thoughts...

Recently upgraded to mountain lion in order to buy the new tall tower for time machine backups. had to get technical support to help with set up as it wouldn't play ball with two computers. all working fine up until last week when the iMac started getting backup error messages. then system restarts independently when using time machine on the time machine wireless network. only stops restarting when I switch the wireless network back to he bt one, which is a pain obviously as can't back up to time machine then. it has to be a problem with airport utility or something wireless but all says all up to date with software etc. all still works fine backing up from laptop on the wireless network, just the iMac is not happy. any help or thoughts very much appreciated.

Hi, many thanks Bob, what you say is not unthinkable at all, although it does answer the question
"what could I do *instead* of ..." rather than the one I actually asked, but seriously ...
Shutting down might be an answer, although it would clear out my tmp directory - which I might not want to have to sort through looking for things I want to save every time I go to work, and also, now that nvram doesn't seem to work for disabling the boot chime, it can get a bit embarassing booting up in a busy meeting if I have forgotten to mute before I shut down. There are all sorts of other issues, such as editing documents, loading web pages and so on that I would have to set up again.
Your suggestion of letting Apple know is a good one - thank you for the link.
Take care,
Mark

How can I get Messages to show the correct time for read receipts?

Messages in Mountain Lion shows the wrong time for read receipts. For example, my iPad will show a message was read at 3:37 pm but if I open Messages on my MacBook, the read receipt shows the time that I opened the Messages app as opposed to the time the message was actually read. This is not too much of an issue if my iPad is handy, but really, shouldn't Messages on my MacBook be able to show the correct time the message was read? It syncs all the other infromation with Messages on iOs.
I should mention that if Messages is running on my MacBook when the recipient reads the message, then it does show the correct time the message was read. It's if Messages was not running and I re-launch it that the read receipt time gets mixed up.

HI,
As far as I am aware Messages marks or time stamps an iMessage at the time of receipt rather then the time you got around to reading it.
I will admit that in most cases reading and receiving as the app opens will be near enough the same time in some conversations.
Adding Time Stamps to Chat is what iChat has always done particularly with AIM based Chats.
The "Sync" in Messages is "display on all devices" and after that each iMessages is dealth with separately on each device.
There is no syncing of deleting/dimssing an iMessages or having read it on another device.

Is there a way to see and have control over who connects to your time capsule wifi network?

Ok, have this question. Have a time capsule wifi network. Have the latest mountain lion on my mac pro. I know if you go into airport utility, and you click on the picture of my timecapsule it shows what clients are connected to my time capsule aka using my internet etc.
What I want to know, is there somewhere I can go on the mac where I can view who is connected to my time capsule wifi in more detail, see amounts of data they are using, and maybe even boot them off, or ban there computer from the network for a while if need be? Trying to assess what family members are using up all our data, and want to ban the appropriate offenders
Even if Mac doesnt have anythink, if you know any third parties from the app store that have an app that is like a "tap" on the top of your Mac that shows networking details, that would be great too!
Thanks heaps!

Nope.. TC are not burdened with controls.. don't you know..
In fact you will find it hard to find a wireless router on the market that mets your specs.. but there is a great 3rd party firmware.. called gargoyle.. this can be loaded like an official firmware in a NETGEAR WNDR3800 which is a fairly cheap very good solid wireless router.. bridge your TC behind this router running gargoyle and you can set quota for all your family members (kids I imagine). Quota can be set for daily, weekly even hourly.. and you can apply throttles or qos.. none of these controls even exist in the TC.

My iMac suddenly no longer connects to wifi network when in KIOSK (username) mode, and only connects when as ADMINISTRATOR mode. Its strange because the iMac has been working fine in KIOSK mode for over a year until 2 days ago.

One of the memory cards was indeed faulty, and the other completely fine
Thanks very much for all your help!
Although there is one little thing that I've noticed. The iMac works properly, but I tried to software update to see if that may help my Minecraft sound issue (as I still don't think only having 2GB instead of 4GB would cause such a problem) but the software update application won't work. Running the "Software Update" from the apple menu on the toolbar gains no response, nothing happens. If I run the software update from system preferences, the application icon appears for a second, then disappears (as in the blank app. icon, the blank canvas with the pencil, pen and ruler in the bottom right corner). It does this every time I try to run it. It did work when the computer was crashing, but this started when on one of the occasions I ran the app. while it was crashing. Since this occured during the crashes, and still occurs now, I'm wondering did something simlar happen minecraft, as it's sound disappeared during the crashes and is still gone now.
However, the computer is now working again without crashes, which is the main thing, thanks for helping me fix the issue
Edit: I would mark the topic as solved, but I'm unsure if this would lock the topic or something simlar, so I'd rather leave it open for any ideas regarding the software update and Minecraft issues I'm having
