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

Configuration

There are two areas that need to be modified in the locationchanger script, Locations and SSIDs. Both of which are case sensitive.

Locations

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"

SSIDs

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

MacOS Notifications

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

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:
