Yosemite [erroneously] displays multiple Shared Instances under Finder

I am having similar issues and none of these leads are working

Try one of these:

1) Finder method:

Finder...Go...Go to Folder and enter ~/Library/Preferences/

Scroll through the list (sort it by name) until you get to com.apple.finder.plist

(It really should be there - its autocreated everytime Finder launches...)

2. Terminal method:

Open Terminal.app and at the shell type to open that hidden folder:

open ~/Library/Preferences/

or

open /User/[your name here]/Library/Preferences/

I have been troubleshooting this issue with my two computers (iMac OS X 10.10, Mac mini OS X 10.10) by following the instructions given here for about 3 weeks. (1. Reboot/Reset Airport Basestation. 2. Delete com.apple.finder.plist.) Issue was resolved in first place but did reoccur pretty soon after again and again. Today I notice that this issue has become persistent. TB steps won't help anymore.

I wonder if something else on your network is trying to keep Wake on Network alive? (AppleTV maybe?) Also - is every computer being reported with multiple names have Wake on Network off?

Unfortunately, this seems to be a Yosemite bug that has no permanent solution at the moment.

I personally know of several bug reports filed with Apple both from beta testers and after the full public release. Reinstalling Yosemite will accomplish nothing and most of the tweaks that seem to make the problem go away will only provide relief for a few days, with the problem recurring within a week.

The bottom line is, we will have to wait until Apple actually fixes this one in Yosemite.

Still the same here happening on all of my Macs on Yosemite (never before under Mavericks, and before.).

None of the proposed tricks helped. Resetting the host name in preferences > sharing helps for a while but suddenly iterations appear again (2), (3), etc. on all machines in my LAN.

It really drives me nuts here!

I am also having similar problems, and none of the fixes mentioned work for me either.

I have four iMacs, but it's only happening to one. Waiting on a solution.

This is happening to my mother's computer too. First Yosemite install hosed her computer. I had to erase her hard drive and re-install Yosemite fresh, and her computer works okay now. But her computer name keeps duplicating under the "Shared" section on the side bar of the Finder window.

Apple, please fix. And please have one of your staff at least acknowledge some of these problems Yosemite is having... dropped WiFi, Duplicate computer names, slow startup, etc. Are you guys fixing these problems??

Same issue, only up to (3) so far so maybe I should be grateful! Following this thread to wait for an Apple fix.

Same issue here on 2009 Mac Pro, Mac OS 10.10.

try this

i had a network issue and your issue and your issue disappeared after doing the below so i don't know if it will work or not but it won't harm to try as they all get rebuilt on reboot

you will need to enter your network prefs again if it's not DHCP

hold shift cmd G and paste this

/Library/Preferences/SystemConfiguration/

then Go

then delete or move

com.apple.airport.preferences.plist

com.apple.network.identification.plist ( i didn't have this file but it was in the network fix so i included it anyway)

com.apple.wifi.message-tracer.plist

NetworkInterfaces.plist

preferences.plist

i deleted these as well

com.apple.smb.server.plist

com.apple.smb.server.plist.lockfile

reboot

i can't test it because i don't have the problem anymore

hope it helps

Unfortunately, this procedure has not resolved the issue on my computer systems. Just deleted all those plists as recommended and restarted the machines. Computers now show with a fresh number under Shared on each system. (You bet the shared items will be multiplied soon.)

soz😟

the only other thing i did was change my share name from the one apple defaulted to

just remembered what i did the exact moment it i resolved it which was to set all my NICs to manual with DHCP (after deleting the files) this set them all to the home domain which immediately solved it i remember seeing them all disappearing in finder , so maybe its the domains you should be looking at???
