Ok. This issue has been documented before but I have not found and fix and do not want to reinstall the entire OS over some bs. 2 days ago I was trying to connect to my friend's WiFi network on my 2010 2.66GHz i7 MacBook Pro running 10.6.8 when suddenly it wouldn't connect. The menu bar status says "AirPort: Not Configured". I cannot go into Network Preferences, it just says "Loading Network..." and does not load it. Other preferences load, but not Network. Repair permissions did nothing. Tried resetting the PRAM. The issue persists on multiple user accounts as well. How to fix?
