I am trying to simply restart my app. To my dismay, I cannot find a

Please enlighten me if I have failed to understand something!!
After perusing the archives, what makes the most sense to me is to
launch a detached shell that executes a simple AppleScript.
The script has a delay of 2 seconds and then simply does a 'launch'.
You're overcomplicating things.
int main(int argc, char **argv) {
if(fork() || fork()) exit(0);
sleep(2);
execl(argv[1], argv[1], NULL);
exit(1);
}
Launch this with a single argument - the path to your application's
executable. It'll background itself, sleep two seconds, and exec your
application.
(Standard disclaimer: typed out in Mail, untested.)
I've got the script working like a champ in a straight terminal
session:
> /usr/bin/osascript '/Users/steve/Desktop/Restart.script'
So now:
NSString *cmdString = [NSString stringWithFormat:@"/usr/bin/
osascript '%@'",[[self scriptsFolderPath
stringByAppendingPathComponent:@"Restart.script"]];
NSTask *task = [[[NSTask alloc] init] autorelease];
[task setLaunchPath:@"/bin/sh"];
[task setArguments:[NSArray arrayWithObjects:@"-c", cmdString, @"
&", nil]]; //the '&' detaches the shell, yes?
& only detaches a command when it's part of a shell command. You're
passing it as an argument to /bin/sh here, which is subtly different.
