These are not your immediate problem, but they will break next. These arguments are incorrect. You're passing the flag plus the value as a *single* argument. This is equivalent to quoting it in the shell. You don't want that. Pass them as separate arguments. See: http://www.cocoadev.com/index.pl?NSTaskArguments > [NSNumber > numberWithInt:pid], // feed in PID for macro $1 > nil]; > > NSTask *task; > task = [[NSTask alloc] init]; > [task setLaunchPath: @"/dev/dtrace"]; This won't work. /dev is for "devices", not "developer". /dev/dtrace is a dtrace kernel device, *not* the dtrace binary. Use "which dtrace" in the shell to find out the path to the dtrace executable.
