NSString *scriptPath = [[NSBundle mainBundle] pathForResource:@"DeleteHidden" ofType:nil];
NSTask *task;
task = [[NSTask alloc] init];
[task setLaunchPath:scriptPath];
The script DeleteHidden had line endings of <cf,lf> which caused an exception on 10.9
removing the <cr> via a hex editor resolved the 10.9 issue
Thanks to all for the cycles.
