#68094 — Could use help: my computer keeps being renamed

Hi. I have an IMac running Yosemite.

For the sake of this post, I'll say my computer is named "Computer."

A few weeks ago, I noticed that my Mac changed its name by adding a 2 
in parentheses: "Computer (2)"

I went into the Sharing preferences and removed the "(2)" so its name 
was back to "Computer."

I did that a few weeks ago.

I just looked in the Finder again and noticed the "(2)" has been added again.

Does anyone know why the "(2)" keeps being added?

Thanks.

Sky

it's a bug in the bonjour proxy. update to 10.10.1 and reboot your
router.

This has been widely reported I had (2), (5), and (10). In my case it
went away when I re-started the AirPort base station. YMMV!

I had a situation with Email Backup Pro software that never seemed to 
work correctly.  It would start it's run, do some sort of system call to 
get the machine's name (more than just hostname on MacOS I think), and 
ultimately the backup was named after my Airport Express box instead of 
my Mac.  And my Mac's name got renamed also.

I'm running 10.8.5 and the developer is one of those endless pits of 
non-support that I'll remember.  Not surprised when they stopped 
supporting the program entirely.  Ultimately, the renaming problem when 
away when I used scutil to rename my machine instead of the Sharing 
preference.

Hi have this issue too.

It is not cured by rebooting Airport router (@Davoud), nor updating 
beyond 10.10.1 (@nospam) (tried both multiple times).

It is documented as an issue elsewhere (e.g. 
http://forums.macrumors.com/showthread.php?t=1804719), and those other 
threads seem consistently to point to problems with how airport handles 
multiple network bands or to issues with the bonjour sleep proxy in the 
Apple TV interfering with the one in Airport Routers 
(http://support.apple.com/en-us/HT201960).  Either way - what seems to 
happen is you end up with two different 'memories' of your machine's 
name in different parts of the same network, and OS X responds to the 
apparent conflict by triggering a rename of your machine (as it would 
if you logged into a network that already had a different machine with 
the name your machine uses).

Two solutions are offered by the other threads - one is to disable 
"wake on demand" on your machine (the part of your machine that 
interacts with the sleep proxy servers).  This might have a negative 
effect on how your machine works while in sleep mode, but nothing 
dramatic.  The second is to change the name of your network location to 
match the name of your machine - no idea why this second one works, but 
seems to.

I've been using the second fix (the location name one) and seems to be 
OK so far.

that should also fix the issue. 

very few people wake their machine via the network so it won't have any
negative effect whatsoever. they normally tap a key or lift the lid to
wake it.

that shouldn't matter.

Thanks everyone for the responses. I'm running 10.10.1 and I'm still 
having the problems. Hopefully Apple will fix it in the near future.

I had this problem on only one of my computers running Yosemite. I fixed
it by adding "--no-namechange" to the "ProgramArguments" dictionary of
the /System/Library/LaunchDaemons/com.apple.discoveryd.plist property
list, setting the name to the correct name in System Preferences >
Sharing (and clicking Edit there to ensure the name was correct there
too), and finally rebooting my router and the computer. I've read
reports that Apple has this fixed in the latest update, but haven't
bothered to remove the switch from the property list yet.

Long time lurker here..

I hadn't noticed this until AFTER upgrading to 10.10.2.  Thank you 
for this information.  I'll try it out ASAP.

It is not an Apple problem, it is a problem with your router.

The router loses the connection to the machine, the machine reconnects,
but the router is still holding the other IP and showing it as
connected, so OS X says "Oh, there's already a machine connected, I
better add (2)" and this repeats.

I've always been able to solve this either with a better router or with
fixed IPs.

it's a bug in the bonjour sleep proxy. it's an apple problem.

it supposedly was fixed in 10.10.1 but apparently the original poster
is still having issues.
