A known issue with tethered caching is that each device connected to the Mac creates a new network connection. Over time, a growing number of network interfaces are created in /Library/Preferences/SystemConfiguration/NetworkInterface.plist. This can cause extended delays when switching networks on the Mac and may cause the Content Caching service to stop functioning. As a result, these interfaces may need to be cleaned up.
The FixTetheredCaching app will check if the files below exist and remove them.
IMPORTANT: This will remove existing network settings, including Wi-Fi and VPN configurations.
