Hello,
since the updates on my system (macbook 10.4.11) last Thursday I get a popup window saying, "your network settings have been changed by another application". I click "OK" but it comes right back. I change settings from work to a dial-up at home and it will not let me access my dial-up since then. I have discussed this with the dial-up tech support as well as an apple support person and can not figure out how to get rid of the pop-up window or get online at home. the updates were in: java , security, Quicktime and itunes. Any assistance would be extremely appreciated.

HELP

Configuration: Mac OS X  10.4.11
Safari or firefox

I am experiencing the same problem. (pop up window stating: your network settings have chagned... ) I have to force quit system preferences to close it. Have you any luck correcting this?

What did you do to "force Quit" system preferences? no matter what I did for two weeks it just kept poping back up. I tfinally just went away. I really couldn't tell you anything specific, because I did a LOT of changing things in my system. Not sure what much of it did. I think the window got sick of me. Have you had any other problems along with the window popping up? I have to go in and reassign all my network settings every time I go online. Any help would be appreciated. thanks

Click on the apple icon in the upper left hand corner of the menu bar. Select "Force Quit" A window opens.. select system preferences, then click on "force Quit" another box opens asking if you really want to do this, click on force quit and there you go. you made the system preferences box close. this doesn't fix the problem we are experiencing. When I open sys pref again and select Network the drop down box comes back and the only way to get rid of the whole thing is to do the force quit operation again. I went to the genius bar and the guy told me to back up my stuff and come back and ask to have my hard drive erased and reinstall the OS and this will probably correct the problem.then you have to rebuild all your data. Seems like a lot of trouble. Before I do this I'll keep researching other means.

If you hit return you get a very brief window of time to use the mouse so hover the pointer over a button before hitting return. It's very brief.

I found some alternate info elsewhere. The issue is with a security patch Apple released. They changed the way PPP and PPPoE passwords are maintained on your system. To fix it you first need to make that lame "Your network settings have been changed by another application" dialog stop popping up. To do this open "System Preferences" and go to "Security". Tick off "Require password to unlock each secure system preference". Now click "show all" at the top. I had to quit "System Preferences" to make the change take effect. Open "System Preferences" again and choose "Network". You will probably get the annoying pop up once, but this time when you click "OK" it won't loop. Notice that the padlock in the bottom left corner is now locked. Click it to unlock. Enter your password (assuming you are the administrator on the Mac). Now click back on the show all button. The Mac will think you made a change and ask if you want to " Apply configuration changes" click "Apply". Once it saves the changes your problem should be fixed. You can go back to the "Security" pane and untick the option you enabled earlier.

There is one catch to this fix that had me stumped for a good while. If you have ever used an external modem on your system there could be PPP settings that you can't get to without having the modem attached. What a pain! I could see "External Modem" in the port configurations, but it was grayed out and I couldn't make any changes. The only way to edit the PPP password was to find a modem and plug it in. "External Modem" became an available option and I could now edit the settings. Such a stupid problem! Hope that nugget helps anyone stuck in a similar situation.

Jean, I'm not sure I understand which settings need to be reset. Is it the user name and password provided by your service provider, the TCP/IP configuration, the port connections? Perhaps if I knew what exactly is being reset I may have an idea.

Hello JAmes,

I did what you say several times but the bug is still there. I can go through it by clicking on the OK with the return key and rapidly close the network window with the mouse on the red button, but....

Thanks for any suggestion

Thanks for the advice --- I've been having the problem for a couple of months and had thought that i had somehow picked up some malware; I'll have to watch those "porn" sites!!!!!!

I used your instructions and --- at first --- they seemed to solve the problem, but it reappeared next time I tried "network preferences".

Does 10.5 fix the problem? If so, I'll defer trying to fix it until I install Leopard. If not, what other possible solutions exist?

Thanks again for the help --- at least I am more certain that there is not a critical underlying problem.

James, you are a lifesaver!!! I have dinked w this for two days including some tech support, to no avail. It all started when I was not able to print or use internet on my windows side via parallels. I did the fix you suggested, reconfigured my network sites, and voila....everything now working perfectly. If only I had seen your fix first. Thank you so much.

The solution works, but only if I leave the security setting on. When I un-checked it, the problem returned. This isn't a serious problem, true, and I hope Apple fix it with the next o/s update.

cruncher, on Jan 8, 2009 8:56:00 pm GMT

In my case the solution was to lock the padlock on the security pane itself. That disappeared the pop-up window. Glad somebody else felt like throwing their Mac against the wall!

Bill McGonigle, on Jan 12, 2009 5:26:56 am GMT

One more variant that worked for me - briefly:

Switch to Show: Network Status
Lock padlock
Unlock padlock (asks for password)
Show All for System Preferences (asks to apply your changes, which you didn't make, but say yes)

Now, go into Network Preferences again and you can modify your settings again without being molested by the devil's sheet.

After I went back in again the sheet came back, but I was able to make my change. How horrifying that Apple is breaking systems with its security updates. A not-so-subtle hint to get on the upgrade wagon that they haven't done anything to fix this.

The idiots at Apple told me I had a "trojan horse" and that I had to reinstall my software, I should have thought to google this first... a friend told me to after he remember having the same problem on a mac a couple of months. You would think Apple tech support would know how to handle his problem!
