Why did my computer name change?

Why would my computer's name change all of the sudden from 'macbookpro' to 'macbookpro-2'?
There's no other macbook pro 2 in my house's wifi.

The name on a network? There still may be a session still connected on the router that never got released. You can reset the router and should restore things back.

Why did iCal Calendar names change to todos?

I was a former MobileMe user and switched over to iCloud. Everything transferred over fine but at some point in the last month all my calendars are now called "name of calendar"todo. Any ideas how this happened?

Hey Gattypyle,
Thanks for the question. You simply need to go back to Day/Week view, then tap the list-view icon once more.

Why does the "Computer Name" sometimes change?

                Not a big deal, just curious, why does the "computer name" sometimes change?
                 The name will be the same, but it will add a number....2,3,4...I always change it back so it doesn't have a numeric value next to it, but just wondering why it happens.
                                        Thanks.

Can also occur after your computer is put to sleep and then wakes back up or after your computer is force quit and immediately restarted. Sometimes the router 'believes' the computer is still connected when it actually isn't. When that computer re-establishes a connection the router 'tells' the computer that a computer with that name already exists so it has to change its name. By default a computer running MacOS adds a number (or increments its number) when this happens.

EM not working Properly after computer name change

Hi Friends,
i hav 10gr2 DB, everything was fine.
last week my computer name changed, and EM stops to work.
so i reconfigure EM through command line.
after that EM started, but when go to 'Performance' or any other tab in browser.
its asks for login and shows 'oldcomputername:orcl:1521' in connection string.
so whats other things , i hav to change?
Thanks

Search every file under $ORACLE_BASE for the old name.
Assuming *NIX use find and grep.
Why do people rename servers? A name is a name is a name. All it ever does is cause problems.

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:

I just installed itunes 11.1.5.5. Now the format in Itunes is changed. when I am trying to add music to my iphone, there is no longer an add button under the Iphone device. Why did they have to change this? Can anyone help, Im tryiong to add music.

How do you add musci to the Iphone? I just installed itunes 11.1.5.5. Now the format in Itunes is changed. when I am trying to add music to my iphone, there is no longer an add button under the Iphone device. Why did they have to change this? Can anyone help, Im tryiong to add music.

Correct. When you purchase devices, they would have stated the OS they needed to work, on the box. This can be overlooked, but it is very important to check when purchasing.
You current OS, is so old, that they technology build into the new devices, is not something your OS understands. It didn't exist when your OS was created, and therefore you need to upgrade the OS to work with the newer technology of these devices.
10.6 software is not downloadable. You must purchase a DVD disc. You can order it from the on-line apple store

Why did you have to change the layout of Firefox?

I would like to know why you have gone and changed the layout of Firefox?
I am still on Fx 3.6.18 because quite frankly 5.0.1 looks horrible.
Why did you have to change everything and move things around. Why couldn't you have given us the same layout as 3.6.18 but with these new upgrades.
I will never download Fx5. 3.6 was perfect.
Also how can I contact Fx without upgrading?

Sorry the old Feedback page - Hendrix - used with older versions of Firefox was disabled near the end of 2010.
In Firefox 4+ versions there's a Help > Submit Feedback... menu item which leads here: http://input.mozilla.com/en-US/feedback <br />
But you can't submit feedback there with an older version of Firefox, currently you need Firefox 5.0 or higher.
The decision to change the GUI was made by Mozilla collectively, not by a small group of developers or by one person. If you put your efforts toward customizing Firefox to suit your tastes, it would be a lot more productive than trying to find out who to blame and where to complain about the changes made to Firefox. Geez dude, it ain't the end of the world. It's only a web browser, which can be easily modified to make it look like you thing it should look.

Why did my base station change names?

For the last 3 years my network had two names. NicTonTimCap and NicTon guest. I wake up this morning to see flashing Amber light and can only find Harry's WiFi Network. The same password worked but why did this happen?
Thanks,
Harry

When you open the airport utility go to the wireless tab.. has the name actually changed for wireless..
If so this might all be part of the way Apple is trying to help you automate file transfers by a strange peer to peer process.. although how it can self setup the airport is a mystery..
I would put it down to a fresh bug in Yosemite.. reset the network names to what YOU want.. if it happens again and you have applecare then ring apple to see if they have some new functionality in Yosemite that automatically changes names of the wireless network.
I presume your computer name is Harry (or some part thereof).

Computer Name changed...why? How?

Had a weird one, thought I'd post it here. I just noticed that my Mac mini's computer name is "administrators-mac-mini". It's weird because I'd previously set it to something completely different.
Anybody know why a Mac would suddenly start calling itself something else?
Mac mini G4, 2nd rev., 512MB, combo drive, BT/AP Mac OS X (10.4.5)

Followup. I checked the system logs and the only interesting thing I see is

Wonder what that's all about. As far as I know, I wasn't setting up or otherwise doing anything with Appletalk or bonjour at that time. Other log files show no activity or connections from nefarious IP addresses. Probably something totally innocuous...but still...weird.

Time Machine and computer name change

I just recently reinstalled the operator system after a computer crash when i did so changed the computer name and now when i go into time machine to restore the settings it only shows up as one sparse disc image.
i have found that when i can mount it manually but the files are not usable and when i mount it with time machine the history does not appear.

Go to System Preferences - Sharing and change the computer name there. You can also, optionally, change the name of your hard drive to further clarify the origin of your backups. Click once on the "Macintosh HD" on your desktop, then click its name to allow you to edit it.

Computer name change and Network name

Recently I changed my computer name from "XY Z's Computer" to one without the dreaded apostrophe and the spaces.
I did this in Sharing under Computer Name:
However, after doing this and rebooting, the new name is there - good - but if in Sharing Preferences, I click Internet Sharing and then click Airport Options, my original name is there, under the title, Network name:
Is there a single location where these changes can be made simultaneously?
Are there any other places where one might find the original computer name?
Is this a bug or simply something not well-documented that I should have known about?

i'd like to know how to do this also

Computer Name changes when waking from sleep

Hi,
I'm running OS X Lion Server on a Mac Mini 2ghz Core 2 Duo and every time it wakes from sleep I get a message saying "There is already a computer on the network named MacServer, renaming to MacServer (2)".
It only happens when waking from sleep. If I reboot or use the mini for hours without sleeping it's fine, but once it's gone to sleep it renames on wake. When it sleeps overnight it's named MacServer (5) by the morning, as it wakes up every two hours or so to re-register itself on the network and each time it renames itself.
I don't have any other compters on the network with the same name. The only other computer is a MBP and has a completly different name.
Here's my setup;
My Mac Mini is wired via ethernet to a Time Capsule. AirPort is turned off (I've tried on and off).
My Mac Mini has a static IP address (x.x.x.40) with DHCP for everything else (DNS, etc.)
The Time Capsule is wired to an ADSL router via ethernet.
The ADSL router manages DHCP and NAT, with IP pool x.x.x.2 through x.x.x.30.
DHCP and NAT are turned off on the Time Capsule (bridged mode).
Wireless is turned off on the ADSL router.
Time Capsule is handling wireless.
I've tried resetting the ADSL router. I've tried resetting the Time Capsule (to factory defaults).
The problem seems to be with mDNSResponder, as the log seems to suggest that it is this daemon that thinks there's a duplicate computer name. I've even looked at the source code for mDNSResponder and the last mod-log entry suggests that a fix was put in for this issue in 2009. It doesn't look like it's fixed it, though.
I've tried doing a fresh install of OS Server several times now and, after the last install, it started happening before I got a chance to restore from a Time Machine backup. i.e. on a completly fresh install and assigning a completely new computer name.
Can anyone help me on this issue? It's driving me insane!

I switched the server's WI-FI off and connected the ethernet cable to the ADSL router instead of the Time Capsule and, after several reboots, sleeps and wakes, there was no change to the server name. The Time Capsule was still switched on, connected to the ADSL router via ethernet, and available on the network, however the server rename issue went away.
I then took the ethernet cable out of the ADSL router, plugged it back into the Time Capssule, put it to sleep, woke it up, and guess what? That right; 'The name of your computer "safserver" is already...renamed to "safserver (2)"'
So, it looks like it's the Time Capsule. I'm going to downgrade the firmware from 7.6.1 to 7.6.0 to see if the last update is responsible. If this doesn't cure it, I'll try older firmwares and, if none of them work it's time for a Genius appointment.
(I khow another obvious question lurks: "why not leave it plugged into the ADSL router?" Answer: "ADSL router doesn't supply Gigabit ethernet.")

Any idea why my desktop drive name changed to '\

Hi.
Just sat down to do some work for the first time in two days and noticed that an external drive on my iMac and a desktop folder have had their names changed. The drive changed to '\ and the folder changed to \
I found my 3-year-old noodling on the keyboard for a few seconds earlier in the day, but don't think that's it. The two new names seem ominously similar and suspicious. The folder was no problem -- I just created a new folder with the old name, copied my files to it, and then trashed the one with the changed name. The hard drive will not let me change its name, however. I can click on the name field, but when I start typing, it tabs to the next item on the desktop.
I restarted, ran Disk Utility to verify the drive in question, and repaired permissions on the internal drive. I do think I have one tiny bad spot on this external disk, but it's been working fine otherwise and I have it backed up. But regardless, this wouldn't explain why a totally unrelated folder on my desktop suffered a similar fate.
Any ideas what caused this, whether I can change the name back, or if it's going to cause problems down the line if I can't?
Thank you.

Do you have children or a cat? I found the same thing after my grandson visited not long after he reached the "mobile" stage. A few minutes banging on teh keyboard of my wife's iMac left the hard drive with an odd character for a name.
Cats are more computer-literate that many people think. When they walk across the keyboard, they seem to know exactly the right keystrokes to make you computer do odd things--if you are lucky. If you are not lucky, cats know how to leave remnants of meals past of worse on a keyboard.

Computer name change after migration

I did a software migration from my macbook to my new iMac. Everything went great except the migration named the new iMac "macbook", the name I used on the macbook. I went to system pref. and did the name change to iMac24 and that works fine for sharing on the local network. However, on the Finder the name of the new computer at Home is still "Macbook", the migrated name. Kinda confusing when looking at the Finder pane, two Macbooks show up, one under shared and one under places.
Also tried to change the name of the Home at the Mac HD but was told couldn't be done.
Is there anyway to change the name of the Home file or am I stuck with Macbook as the name for my iMac?

The Home name I presume is your "short" name.
You can change the short name in Accounts by unlocking the padlock and right-clicking the Account and selecting Advanced Options.
Pleased note the Warning and the required reboot.
I suggest being sure your backup is up-to-date before changing the short name.

Computer Name Changed

Hello.
Recently I noticed that the computer name of my macbook pro changed from Erugalatha's Computer to Erugalatha's Computer (2).
I didn't update/install/change anything lately so why would this happen?
I've also noticed that the Applications folder is becoming really slow to access ... when I click on it in Finder it takes about 3-4 minutes to render all (149) items in it.
If I click off onto another folder and back to Applications it renders them all again - another 3-4 minutes.
Any ideas what could be wrong?

No ... it's not part of a network. I connect to the internet using a 3G Card (huawei) but am rarely connected on wireless routers - not lately anyways.
I'm not running windows in bootcamp - if that's what you mean? I run windows in Parallels but none of those virtual machines are named "Erugalatha's Computer".
I'm stumped but it's not a big deal - just wondering why it would happen without notification or why the computer name would be even allowed to change without somebody going in and manually changing it. Nobody uses the machine but me.
Is there a way to change it back and keep it like that?

Why did my computer name change?
