refresh-wifi

Small app to remove stale macOS WiFi preferences from /Library/Preferences/SystemConfiguration/ to "refresh" WiFi.

It basically executes this shell script:

sudo rm -f
    /Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist
    /Library/Preferences/SystemConfiguration/com.apple.network.identification.plist
    /Library/Preferences/SystemConfiguration/com.apple.wifi.message-tracer.plist
    /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist
    /Library/Preferences/SystemConfiguration/preferences.plist

Motivation

After some time, or after macOS updates WiFi stops working in stable way. Either it loses connection every few minutes, requires restarting, router restarting, etc.

Often it's recommended simply to remove WiFi preferences and restart your computer. It works for me and people around me, thus I created this app so not only me, but less tech savvy people could do this themselves without any help.
