Ask Max: Safari and iChat Quitting Unexpectedly
Safari has been quitting on me and iChat has been having some trouble staying connected. Any reason why this would happen?
It is not a clear symptom but it sounds to me like you are having network connectivity problems. This could be caused by three possible issues.
It could be the network you are on, so you should take your MacBook Air out of the house and see if the problem happens on other networks. Try going to a coffee shop with free Wi-Fi and see if you can get Safari to crash or iChat to logout.
If it happens on another network, then you should next look at your OS X software. You should do an Archive and Install of the Mac OS from an Install DVD. This will replace your OS with a new version of the software but leave your personal data intact. IF that fails to help, try deleting your Network preferences. Then restart your MacBook and test your Safari and iChat.
- Macintosh HD/Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist
- Macintosh HD/Library/Preferences/SystemConfiguration/NetworkInterfaces.plist
If that fails to resolve the problem, it is probably hardware related. If you had been connected wirelessly to the internet, try an ethernet connection and see if it is the network interface or your whole system. Then when you have it pinned down, you can be certain it is hardware related. Take it in for a service diagnostic at an Apple Authorized Service Center. They should be able to pinpoint the problem if you give them the testing info gathered from the above troubleshooting.
