Chosen Solution
Whenever I open the networking section of system preferences I get a message that says “Your network settings have been changed by another application” when I click OK, it just pops up again straight away. It is very hard to quit System Preferences and sometimes i have to hold down Cmd Q while pressing OK. I dont think there should be any apps changing my settings. I am using a wireless connection with an airport express.
I can’t take the credit for this fix. I did find this solution on the Apple discussion board. It looks like a promising solution though: To stop the pop-up, Go to System Preferences: Security. Check the box next to “Require password to unlock each secure system preference.” Then lock Security. Try this cure for Security update… http://discussions.apple.com/thread.jspa… The locations are actually… /Library/Preferences/SystemConfiguration/preferences.plist /Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist /Library/Preferences/SystemConfiguration/com.apple.nat.plist
