Mac OS X Mavericks 10.9.4 and App Store not notifying about or automatically checking for updates event though all settings are correct

Question

Seems as though the automatic updates is not working. I have checked the boxes and unchecked them as well. Still no auto updating for the OS. They do work for my apps though. Attached is a command shell screen shot.
    AnonymousUUID = "A08EFDE1-D713-4BEA-93CD-01978C07BCD6";
    AutomaticCheckEnabled = 1;
    AutomaticDownload = 1;
    ConfigDataInstall = 1;
    CriticalUpdateInstall = 1;
    DidRegisterLocalUpdates = 1;
    IgnoringUnseenRamped = 0;
    LastAttemptSystemVersion = "10.9.4 (13E28)";
    LastBackgroundCCDSuccessfulDate = "2014-07-06 01:56:09 +0000";
    LastBackgroundSuccessfulDate = "2014-07-06 01:56:09 +0000";
    LastFullSuccessfulDate = "2014-07-06 01:55:04 +0000";
    LastRecommendedUpdatesAvailable = 0;
    LastResultCode = 100;
    LastSessionSuccessful = 1;
    LastSuccessfulDate = "2014-07-06 01:55:04 +0000";
    LastUpdatesAvailable = 0;
    PrimaryLanguages =     (
        en
    RecommendedUpdates =     (
    SkipLocalCDN = 0;
    lastDownloadError =     {
        code = "-1001";
        domain = NSURLErrorDomain;
        userInfo =         {
            NSErrorFailingURLStringKey = "http://swcdn.apple.com/content/downloads/20/37/zzz061-8477/kGNCGM7LcCG5DGMqpDxQc P5pGN4xRxtBDH/SecUpd2010-005Snow.pkg";
            NSLocalizedDescription = "The request timed out.";
Any assistance would be greatly appreciated.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.
