'Your network settings have been changed by another app' - THE SOLUTION
Posted: Sep 28, 2008 11:30 AM
This currently reported problem, which manifests after applying Security Update 2008-06, can be fixed permanently by removing the following preferences files:
Go to Library/Preferences/SystemConfiguration and delete the following (suggest make copies to the desktop first if in doubt):
All these files will regenerate as necessary when the associated system features are accessed. If you're using Airport or Internet Sharing you'll have to reestablish the appropriate settings, because these will have been lost when the preferences files are removed. Small price to pay, however for a permanent, and very simple solution to this irritating problem.
These solutions have worked for many:
I haven't had the problem myself, but this post by ejp1684 seems to have offer a solution:
Once in the network prefs and the popup appears, place your mouse over the place where the "Show All" button is (behind the popup). Then, hit Return - which gets rid of the window and immediately the window is gone, click on the 'Show All" button. I then get a window asking me to save etc, the changes. You can click on any of them and you should be back in the prefs window. Then, when you select the Network prefs, you should be able to change things. If this doesn't work, I found that I had to use the mouse button to click on both the "OK" button on the popup, and then quickly switch to the "Show All" button - took me a few times to do it!
Even if you can't change the settings, at least you won't have to do a hard shutdown.
This post by MacStrong also provided a solution that worked for some:
If you recently updated or run a disk utility on your Mac this may have altered your sharing preferences. Go to System Prefs>Sharing Prefs and go to Network Time. If you have it checked, uncheck it and then recheck it. I just fixed a Mac by doing this. If it is not checked try checking and unchecking it.
Thanks, it works VERY fine - all troubles resolved. I agree re-enter settings is a small price. A tip: if you write somewhere seting BEFORE throwing plist files, the price is smaller and time wasted is zero.
The problem doesn't show if preference panel requires password to change settings (the other iMac of mine got no troubles for this reason - verified).
