If you’ve recently updated to Mac OS X Lion 10.7.2, you may experience network problems. Google Chrome will forever load GMail. Or Gilgamesh will spin its wheels in silence, never logging the user into the network. The problem has been traced to its source: As part of the update process, Apple installs a bad certificated, which prevents HTTPS websites from loading.
- Ensure your Mac has the correct date, time, and year. If your computer thinks it’s 1970, HTTPS certificates will be rejected as too new. The Mac firewall may be preventing the date and time synchronization service from working; go to System Preferences, Security & Privacy, Click the lock to make changes, and then Stop, so that the status is Firewall: Off.
- Try opening Keychain Access.app. It’s in the /Applications/Utilities directory. If the Keychain program won’t load, navigate to /Users/YOURUSERNAME/Library and delete the file login.Keychain, reboot, and open Keychain Access.app again.
- Select the Certificates category. Delete the Unknown certificate.
- Reboot.
- Refresh the application that wasn’t working before. If it still doesn’t work, quit the program (press Command +Q) and start it again. If a web browser loads an HTTPS website, but doesn’t display it properly, force refresh by holding Shift and clicking the refresh button.
Update: The above steps are only a temporary solution. As soon as the computer restarts or hibernates, the problem starts all over again.

Thanks for posting this. I was wondering what the cause of this was on 10.7.2. Let’s just hope that Apple gets this fixed in 10.7.3……
