OS X :: Unable To Set Network Preferences / Network Preferences Changed By Another Application
Aug 14, 2009
I am running OS X 10.4.11 on a "pod" iMAC. When I open system preferences and click on network, I get a pop up window that states my network preferences have been changed by another application. When I click on the green "OK" box the pop up goes away and comes right back. This is driving me crazy because when it gets into this cycle it's almost impossible to get out of the preferences panel or even check the settings! It's like it gets into a closed loop and won't let you do anything.

when I open my Network in System Preferences, "Network settings have been changed by another application" pops up and every time I click Ok, it pops up again, not letting me be able to access any other option in the Network window. The wireless icon has disappeared from my top bar and the only way I have managed to get online is via my ethernet cable. I have had nothing but problems since I started using my O2 Wireless Broadband dongle and I've noticed that behind the "Network settings have been changed by another application" notification, I can seen the Dongle has appeared as a new network connection option... but was never there before today (have been using the dongle for two months now)

My neighbor has an IMac with OS 10.4.11 installed. When I open System Preferences and select the Network icon, the Network window comes up but it is overlayed with a message that states: "Your network settings have been changed by another application." When I click OK, this same overlaid window comes back.
The only way I can get out of System Preferences at this point is to do a Force Quit. In other words, because this overlaid window appears, I am unable to access the Network window to look at TCP/IP settings, make changes, etc.
Next I went into System/Library/Preference Panes/Network.prefPane(more info) to look at the application that appeared in the "Open with" field. It stated "System Preference." I replaced this with a new "System Preferences from the Applications Folder, but the same thing happened - even after I rebooted the computer.
Please let me know how to solve this problem so I can access the Network System Preferences properly.
Thank you.

iMac OS 10.4 - was working with dial up modem but wanted to plug into my network for high speed internet access - after plugging in RJ45 cable, the network was not accessed but the computer continued to go the dial up route. When attempting to change network preferences a flap keeps appearing saying the preferences have been changed by another application - this flap appears over and over and will not allow preferences to be changed. Dial up still works by clicking on the phone icon at the top of the screen. Any way to reset this without reinstalling the system?

I am running an iMac G5 (just pre Intel) using OS 10.4.11. My internet is via an external modem, ethernet connected. Everything is working fine (as far as I know!) However, for no particular reason I opened "System Preferences" and on clicking on "Network" was confronted with this:- [URL]. On clicking the OK button nothing happens and the only way to get out of System Preferences is to Force Quit it. As I can't get into "networks" in System Preference, I have no idea how the settings have changed. I can't remember when I last installed any new software - it's also ages since I looked at that section of System Preferences.

My isp (Comcast) informed me that I could no longer send emails unless I changed my email port from port 25 to port 587. When I open my network preferences to make the change I get a message that my network preferences have been changed by another application. When I cancel the message it reappears and will not allow me to do anything even quit network preferences.

I used to have a VPN for my office set up in Network preferences. Something messed up all my network preferences, but I am able to connect to my wireless network, but when I go to set up my VPN connection again and click Apply, nothing happens and the connection does not save. I also cannot edit my Locations.

My problems are getting bigger and bigger:
1. I could not activate my airport card after installing 10.6
2. I erased all data in system configuration as other threads told me
[URL]
3. Then my MB said that there is no airport card installed (but it is)
4. After that I tried to reinstall 10.6 but DVD stopped loading and said it interrupted
5. Now I�m even not able to open network preferences! It loads, and loads, and loads...
6. I installed 10.6.1 but nothing happened
I feel like snow leopard (and my attempt to clear the situation) killed network on my MB-Pro.

apologies if this has been answered else-where but Ive looked and found no solutions. My problem is that I cannot access network preferences. I can access system preferences and turn my airport on/off via the toolbar, but I cannot actually open the network preferences without system preferences unexpectedly quitting. I have to access my universities VPN to read an e-book for an exam, so this is quite frustrating right now,

I'm posting here out of desperation and to end my eternal head-scratching over how to fix this... I'm running os x on a macbook pro, and I've never had any problems switching between different wifi networks. However this past month I switched service providers at home, and discovered that my mac automatically tries to connects to what I assume is the neighbors' wifi now (which is password protected, making it even more strange).
I can make it connect to my own network instead by pulling the airport status icon on the top bar down to it but it's obnoxious to have to do this every time I start up the computer.I know the way to fix this is to go into network preferences and change the order of preferred networks, but then i'm hit with the kicker.... for some reason, i cannot change any of those settings! They show up grey and unmodifiable. These are screencaps of what I'm talking about:any thoughts on what might be causing this or how I can fix it? Forgive me if there's some super obvious solution... but I cannot figure it out.

I'm getting a message every time I open Network in System Preferences saying "Your network settings have been changed by another application". I click OK, and the box goes away and immediately comes back. It means I cannot use the Network part of System Preferences at all, because this message is caught in some kind of loop, and won't go away.

For school, I need to set up a VPN connection to be able to connect my MacBook to the internet. While my school offers the Cisco VPN Client with a preconfigured PCF settings file, I would much rather use Mac OS X's built-in VPN capabilities, through the Network Preferences. Now, my problem is that I don't really know what to do to get this working. Using an online password decoder, I already found out what the password for my school's VPN connection is. But how do all the settings translate between the Cisco VPN Client and Mac OS X's VPN configuration screen?
The PCF file tells the Cisco VPN Client to use Group Authentication, with a group name and a group password (the one I already decrypted). These are already filled in. When starting a connection, I am then asked to fill in my student login details. Now, in the VPN settings screen in System Preferences, there is a box for Account Name. Am I right in thinking this is the box where I fill in my student ID? Or does the group name go here? Then, when I click Authentication Settings..., I can fill in a password. I assume this is where my student password goes? Or should I fill in the password I decrypted?.................

Been a rough two weeks. I had the issue of my iMac not loading passed the grey screen. No keystrokes were working so I had to bring it in to get repaired. I was told some optic something cable had to be replaced.
Well, initially that didn't work but it just ended up taking forever too boot. 20 or 30 minutes. Now it is loading fine and Windows is also loading fine with bootcamp.
However, I can't get in to turn on my USB wireless adaptor for Sprint. I can open the system preferences and I can also go in to any other option without problems, but if I click "Network" it says Loading Network, then hangs up. I need to force quit and retry. Same results. Anyone know how to repair that? I have tried Disk Utility and it says no problems. Diskwarrior doesn't let me do much since I am booted to that drive.

I have recently begun to use a fios router for my home network. When originally set up by fios they set the security to wep, and I set my network prefences as such. Since then I have changed the router to wpa security My network prefences still shows that wep encryption is being used. It still connects to the net but I can't figure out how to change it to reflect wpa security. Or since I am connecting to the net , is it necessary.

Something has happened in my Network preferences and I believe it happened while doing a Spotlight search. When I open the Network preference window, I get an almost instant error dialogue stating "Your Network settings have been changed by another application". As soon as I hit "OK" to dismiss the dialogue box, it comes right back. If I'm really quick, I can get back to the main preferences screen before the warning reappears. I've tried logging out, rebooting, trashing the Library --> Preferences --> apple.networkConfig.plist file (followed by a log-out) and nothing has made a difference.

I'm running OX 10.4.11 on a G5. I have airport on my computer and at one point was able to share files from my desktop to a laptop. However at some point something happened and I can no longer do this.
I can't get into my network preferences as the following message comes up - "your network preferences have been changed by another application" and I have to force quite to get out of the window.
I have since purchases airport express and my husband got it to work at home. Now I just tried to install it on my desktop and it won't work. There are probably numerous problems here.

In the dropdown, I have QLM WiFi (which I have no idea what that is), National Access - Broadband Access (which is my wireless card) and Automatic. Whenever I make a change and hit the "Apply" button, my MBP freezes.

I have just changed my ISP on my windows 98 machine. Now I am working on the mac and trying to download a message with Mail but it is not working. The computer is connected to the internet ok and I can see the message in my webmail in Safari but it will not download. I have changed my account details in mail preferences but obviously I have missed something. The help file told me to check my network preferences but when I click on that, a dialog box keeps dropping down from the top to tell me "my network settings have been changed by another application" and there is a tab to click "ok". That is all and when I click that, it runs over and over again and doesn't let me do anything else. I don't know what has been altered but I do not want to alter any settings to my broadband connection because that works fine. That is the main trouble I have with a mac.

My computer just got back from the shop (in Vienna, im studying abroad till august) because my computer wouldnt start up anymore after crashing multiple times. They replaced the RAM and said that they couldn't get airport to work. but that wasnt exactly the whole story. Network Preferences apparently doesnt exist anymore. I've tried to locate the com.apple bits that should be resettable, and I've tried a PRAM restart. still no network settings, and no internet at all. Super frustrating since i just picked him up today.

Im trying to get into my Network preferences, but it is not letting me. All that I am getting is the main page for system preferences and it says loading network. There might already be a thread for this, but I couldn't find it.

I have an iMac OS X 10.7.3 (purchased in late 2010) with all updates current. I use AirPort to connect to my Linksys router with a WPA2 password.
Nearly everytime I wake my computer from sleep, my wireless router is disconnected, even when I have set my settings and clicked on the lock to prevent further changes. My router always shows on the list of available connections with full strength, but it is more often than not extremely difficult to get it connected again. It says "Could not join "myRouter". A connection time out occured."Â I usually have to use the assistant and go through the steps, which usually includes re-typing my password four to five times before it agrees that I know my own password (which is fairly simple to type, I can't possibly be entering it incorrectly that many times).
I downloaded and installed an update [URL] that quote: "resolves an issue that may cause an iMac to not automatically connect to a known Wi-Fi network after waking from sleep. It is recommended for all iMac (Late 2009 or newer) users running 10.7.3." Â
I tried setting a new location, and set the DHCP setting under TCP/IP to be manual. I was successful in connecting to the internet that time, and locked the settings to prevent further changes, yet the first time my computer woke from a sleep, the lock was unchecked and the settings were changed back to automatic. And I was disconnected yet again.Â
This has been going on for months, but in the last couple weeks I have found I am now unable to lock the lock to prevent changes, no matter if my Location is set to automatic or one that I have created. Really looking for resolution as this is wasting so much time, I am on and off the computer multiple times a day.Â

My Wifi printer is definitely connected to my Network but when I try to connect it to my iMac using the System Preferences it does not show in the available printers window. How to get connected? Just changed to BT Infinity and installed the McAfee Security package could this be the cause?

I have: Power PC G5 dual 2.3 w 10.4.11 os, Lost Internet connection. (ethernet cable direct to router), No known cause. Checked router,cable etc. All work fine w other computers etc. router does not "see/read" when cable connected to G5. I figured Ethernet card is dead. Can't afford new card figured I'd try: Net gear G54 wireless USB adapter, just to get back online. Downloaded driver for Mac etc. Went to System Prefernces to set up. Opened System Preferences then Network, Automatically this message drops down: "Your network settings have been changed by another application" When I click "ok" same message automatically drops back down. Cannot access "Network settings" at all.

A few days ago my email was hacked into which sent a spam email to all my contacts. I changed my password to that account, warned everyone in my contacts, and haven't had a problem with email since. However, I tried to do the 'delete all cookies' again and when I go to safari/preferences/privacy...there is nothing on that screen under that tab. Not even a question mark. I changed my history items to be removed every day from every week but don't think that would be the issue.Â

I changed the short name of my home directory oblivious to the consequences. I have searched the internet high and low and have found a few threads already posted (including an Apple support article) that relate directly to this issue. However, although the root of the problem is the same in that I changed the short name, the outcome is slightly different and I can't restore all my preferences in the manner detailed in these articles. I have a Mac OS X 10.4.11. Here is exactly what I did and what is going on:
1. I went into Get Info. in the home directory icon in Finder.
Say the original name was john, I changed it to Fred.
2. Since then, when I open any applications such as Skype, iTunes, iCalendar etc. all of the settings have been reverted to default making it appear as if I've only bought the Mac. However all my documents and music files are still there and can be accessed normally in the newly named directory. My desktop and widgets are also fine.
3. Now when I go to Macintosh HD and click into users there are 3 things:
- The newly named home directory Fred with the house icon.
- A folder with the old home directory's name, that being john. Inside there are Documents, Library, Music and Pictures folders but only the Library folder seems to contain anything important, which I hope are all my preferences. The other three are effectively empty. Like I said I can access my music files etc. normally.
- Lastly the shared folder.
I haven't turned off or restarted my laptop because reading on threads it appears as if I can cause damage or end up not being able to access my mac. The two solutions I've found online are these: [URL]. The problem with this one for me is that I can't rename the new directory with the old name - it just won't let me. [URL]. The problem with this solution and another I found is that I think they are assuming the old directory - john - is in fact still a directory but in my case it is a folder.

I have a home network running 3 PC's(with XP) and 2 Macs (with Tiger OS X 10.4.8). Mysteriously one of my Macs(MacMini) refuses to show a Network icon in the Finder sidebar? I have used the Go > Network menu to try to get a Network icon, but this does work. Yesterday I did a scheduled Mac OS system update, and it seems that since then I have not been able to see/get a Network icon in my Finder.
Has anyone else experienced this problem? PS - I am able to use the old 'GO > Connect to Computer' method, then type in the smb://myOfficePc, and access shared files on other PCs on the network. So networking is configured properly on this MacMini.
