Automatically power off WiFi when connected to Ethernet, power back on when disconnected from Ethernet -- Tested on macOS Monterey 12.4
Forked from pesqair/network-check, check out his blog post that inspired this project.
Some assembly may be required -- Depending on your hardware configuration (what you use to connect to ethernet), your LAN interface may have a different name, and may need tweaking for this to work. This iteration was tested using a Lenovo docking station, which macOS recognizes as Hardware Port: ThinkPad TBT3 LAN rather than a more traditional Hardware Port: Ethernet you may see on a desktop with dedicated ethernet ports.
- Clone this repo and
cdinto it. - run
./setup.sh --installto install the script to/Users/Shared/network_autoswitcher.shand load the .plist inlaunchctl. - That's it!
Assuming all goes according to plan, the script should automatically run whenever a change is detected in the following locations:
/etc/resolv.conf/Library/Preferences/SystemConfiguration/NetworkInterfaces.plist/Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist
If you're connected to Ethernet & WiFi, WiFi will be turned off. When you disconnect from Ethernet, WiFi will be turned back on.
If this isn't for you, or you just need to uninstall it, you can use the setup.sh --uninstall to remove the script and launch agents.
