Bluetooth Proximity Lock for Macbook

Posted on November 25, 2008 by sax

I wanted to have my macbook automatically lock and unlock based on if I am in the room or not automatically. Best way to do that I figured would be bluetooth, since I always have my phone on me, and it has bluetooth. From there I proceeded to google.

Pointed me to

http://www.apple.com/downloads/macosx/system_disk_utilities/proximity.html

he also includes a script to automate syncing your phone book and such too

Another utility in my searching, is called JackSMS

http://www.macupdate.com/info.php/id/21860

JackSMS does some cool stuff like, say someone tries to access your laptop while you’re not there – the built in isight camera will take their picture and email it then, so I wanted to use JackSMS as well.

Proximity allows you to set scripts for when you arrive or when you leave, so here are the applescripts I used:

lock.scpt:

tell application "JackSMS" to set lock screen to true

unlock.scpt:

tell application "JackSMS" to set lock screen to false

update: a better proximity script, copied below, courtesy of:

lock.scpt:

global okflag
set okflag to false
set front_app to (path to frontmost application as Unicode text) -- So we can switch back to this after running the fade
 
-- check if iTunes is running
tell application "System Events"
        if process "iTunes" exists then
                set okflag to true --iTunes is running
        end if
end tell
 
 
if okflag is true then
        try
                tell application "iTunes"
                        set currentvolume to the sound volume
                        if (player state is playing) then
                                repeat
                                        --Fade down
                                        repeat with i from currentvolume to 0 by -1 --try by -4 on slower Macs
                                                set the sound volume to i
                                                delay 0.01 -- Adjust this to change fadeout duration (delete this line on slower Macs)
                                        end repeat

So he said “She tried to call earlier, but was at dinner and didn’t have service.”

So I said, “Oh, so it was a Buffet?”
