Some users reported networking issues on the latest Mac OS 10.9 Mavericks. I got this tip from my colleague, and it seems to fix the intermittent network problem.
The fix is to create or edit this configuration file /etc/sysctl.conf . Add or edit this line
If you are familiar with editing the configuration file using vi or emacs, this is all you need to know. If not, here are the step by step instructions:
- Open Terminal in Applications -> Utilities folder.
- Type this command to invoke pico editor. Enter your password to continue.
sudo pico /etc/sysctl.conf
- Add or edit this line
- Press Ctrl+o to save the file. Press enter for confirmation.
- Press Ctrl+x to exit out of the pico editor.
- Reboot the computer.
