I do something similar in an app -- on first launch, the app needs to set a
global pref, then it quits and re-launches. I tried several strategies
(some with major problems), and one worked great and reliably:
on startupCheck()
-- do some checks here
-- if checks require a relaunch then do the following
set relaunchPath to "'" & the path of the main bundle &
"/Contents/MacOS/myExecName" & "'"
do shell script (relaunchPath & " &> /dev/null &")
quit
end startupCheck
By pointing to the actual "executable" (which I am generically labeling
myExecName here) in the app bundle, and "executing" it in the shell script
command, I am able to launch a new instance of the app before quitting the
old one. As far as I know, this is the only way to have two instances of an
app going from a single app installed on the disk. All the other typical
"launch" commands I tried were just making the current instance of the app
active. So in this case, I set my prefs, launch a new instance of the app,
and then quit the old one. It all happens fast and seamlessly.
