Mac OSX Wi-Fi Location Changer
- Automatically changes the Mac OSX network location when Wi-Fi connection SSID changes
- Allows having different IP settings depending on the Wi-Fi SSID
Note: Mountain Lion compatible
There are two areas that need to be modified in the locationchanger script, Locations and SSIDs. Both of which are case sensitive.
Edit locationchanger and change/add locations to be set:
Note: Ensure you use the exact names as they appear under "Location" in OSX's System Preferences -> Network
# LOCATIONS Location_Automatic="Automatic" Location_Work="Company Intranet"
Edit locationchanger and add/edit SSIDs to be detected:
# SSIDS SSID_TelekomPublic=Telekom SSID_Home=HomeSSID SSID_Work=WorkSSID
Edit/Add SSID -> LOCATION mapping to list:
# SSID -> LOCATION mapping case $SSID in $SSID_TelekomPublic ) LOCATION="$Location_Automatic";; $SSID_Home ) LOCATION="$Location_Automatic";; $SSID_Work ) LOCATION="$Location_Work";; # ... add more here
The script triggers a MacOS Notification, if you don't want this just delete the three lines that start with
osascript around line 57. If you add or delete Locations, the case needs to be updated.
case $LOCATION in $Location_Automatic ) # do stuff here you would do in Location_Automatic osascript -e 'display notification "Network Location Changed to Automatic" with title "Network Location Changed"' ;; $Location_Home ) osascript -e 'display notification "Network Location Changed to Home" with title "Network Location Changed"' ;; $Location_Work ) osascript -e 'display notification "Network Location Changed to Work" with title "Network Location Changed"' ;; # ... add more here esac
Copy these files:
cp locationchanger /usr/local/bin cp LocationChanger.plist ~/Library/LaunchAgents/
Should you place the locationchanger script to another location, make sure you edit the path in LocationChanger.plist too.
Make locationchanger script executable:
chmod +x /usr/local/bin/locationchanger
Load LocationChanger.plist as a launchd daemon:
launchctl load ~/Library/LaunchAgents/LocationChanger.plist
Logfile location can be adjusted in locationchanger, around line 12:
