Have you tried providing the absolute path to the tool in the launchd plist and using the "Program" key to define the location of the tool?

That worked. I am eternally in your debt. On Wed, Dec 6, 2017 at 5:09 AM, Stéphane Sudre <ssudre@intego.com> wrote:

I plan to write a moderately complex daemon but must learn how with a very simple one.

system.log is full of:

Dec 6 00:02:47 Michaels-Mac-mini com.apple.xpc.launchd[1] (com.frescologic.hello): Service only ran for 0 seconds. Pushing respawn out by 10 seconds. Dec 6 00:02:57 Michaels-Mac-mini com.apple.xpc.launchd[1] (com.frescologic.hello[1386]): Service could not initialize: 16F73: xpcproxy + 11769 [1505][34964CF1-9965-3B4D-ADC7-6FBC6669C56D]: 0x2

I googled for "Service could not initialize: 16F73" but found no insight.

My source code:

=================

#include <stdio.h> #include <stdlib.h> #include <unistd.h>

int main(int argc, const char * argv[]) { FILE *outFile;

if ( argc != 2 ){

fprintf( stderr, "Usage:\n $ %s world\n", argv[ 0 ] ); exit( 1 ); }

outFile = fopen( "/tmp/foo", "w" ); if ( outFile == NULL ) exit( 1 );

while ( 1 ){ fprintf( outFile, "%s\n", argv[ 1 ] ); sleep( 10 ); }

return 0; }

========================

My configuration:

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Label</key> <string>com.frescologic.hello</string> <key>ProgramArguments</key> <array> <string>hello</string> <string>world</string> </array> <key>KeepAlive</key> <true/> </dict>

/usr/local/libexec/hello and /Library/LaunchDaemons are both owned by root with group wheel.

Thank you for any advice you can give me.
