Detect if you're being debugged on OS X. Apple's AmIBeingDebugged() won't handle a debugger not using ptrace and is insufficient.

	#include <mach/task.h>
	#include <mach/mach_init.h>
	#include <stdbool.h>

	static bool amIAnInferior(void)
	{
	mach_msg_type_number_t count = 0;
	exception_mask_t masks[EXC_TYPES_COUNT];
	mach_port_t ports[EXC_TYPES_COUNT];
	exception_behavior_t behaviors[EXC_TYPES_COUNT];

task_for_pid() leak when dev ID signed

	// task_for_pid leak
	// IMPORTANT To reproduce this bug, you have to sign this program with a developer ID -- do not use a self-signed certificate or run as root!
	// This code will cause taskgated's memory usage to grow (see activity monitor)
	// Link to Xcode project with included info.plist: http://tinyurl.com/kps28av

Spinning progress indicator troubles, ugh

	#import "ZGAppDelegate.h"

	@interface ZGAppDelegate ()

	@property (nonatomic) NSTimer *timer;
	@property (assign) IBOutlet NSProgressIndicator *progressIndicator;

	@end

	@implementation ZGAppDelegate
