Hmmmm... would appear that you need to be actually logged in to enable the additional menu features.
Have you tried deletting the plists for MAS?
This page might help you out...
http://www.macobserver.com/tmo/answers/how_to_identify_and_fix_problems_with_the _mac_app_store
Failing that, I will have to throw this back to the forum to see if anyone else can advise further.
Let me know how you get on?
Thanks.

  • Mail not working after installing Mavericks

    Mail stoped working after installing Mavericks!

    Check this out. It worked for me and is related to a problem in Accounts.plist...
    The problem was caused by dodgy entries in the accounts.plist file in my User Library folder. It appears that either when I upgraded to Mavericks this file gained hundreds (possibly thousands) of spurious entries, or maybe these entries were in there before but previously the OSX/Mail combination was more tolerant. When I removed these the problem with Mail disappeared. Here’s what I did….
    1> Make the user Library folder visible - in Mavericks this is a lot easier than Lion/Mountain Lion. Simply open up your user directory in Finder, select menu View>Show View Options, and select “Show Library Folder”
    2> Navigate through username>Library>Mail>V2>MailData and select the Accounts.plist file. If this file is multiple megabytes (mine was 40+mb) then this is likely the cause of your problem (once sorted mine ended up at 19k in size!)
    3> To be safe, make a copy of this file (I placed the copy on my desktop).
    4> Using your chosen text editor (I used Text Wrangler but I’m sure TextEdit would work just fine) open the Accounts.plist in the MailData folder (not your backup copy) and take a look. If it’s the same as me you will find hundreds and hundreds of entries for the same mailbox repeated in there. Mine was an old MSN mailbox that I never use any more (I’ve seen in other forums that other Hotmail type accounts also seem to be the culprits in this context). There will likely be two lots of repeated data, one in the XML “DeliveryAccounts” <array> section, and one lot in the “MailAccounts” <array> section.
    5> Delete (keeping in mind the need to select the XML sections correctly from <dict> to </dict> completely) all those extra entries that you found, keeping the mail accounts you do need, in the XML and save the file.
    6> Mail should open up nice and fast again and not eat your system
    7> If this did not work, and causes problems because of over eager deleting in <5> you can replace your broken Accounts.plist file with your backup and try again.

  • App store not working after installing Mavericks

    After I installed OS Mavericks the app store no longer responds. This means I cannot install any of the updates. The notes app is also not working. I can start the programmes but they do not respond or close. I have to literraly close them through the activity monitor.
    Is anyone else experiencing the same issues? Is there a fix for this?
    Kind Regards,
    Micky Kieboom

    I am having the same issue. Why is Apple taking so long to respond?

  • Dock not working after installing maverick

    After installing Maverick on my Macbook Pro, my dock which is positioned at the bottom now freezes. Prior to update, just placing my cursor at bottom of screen would bring up the dock. Now, it either doesn't come up or I have to place my cursor down there several times before it finally pops up. Anyone else experiencing this issue?

    Revealing the Dock while in a full-screen app requires not only moving the cursor to the bottom of the screen, but keeping your finger on it or moving the cursor along the bottom edge (or other "tricks") to reveal the Dock.
    SUPER ANNOYING TO ME
    Many users may like that way of operation, perhaps a great majority. But hundreds of thousands may find it annoying to have this cognitive pause imposed and would rather have the dock appear accidently once in a while when moving the cursor close to the bottom area of the display.
    This worked before Mavericks:
    Setting the Dock autohide delay to zero (in Terminal, with write defaults...) removed this annoyance. As soon as your cursor's at the bottom of the screen, the Dock's there.
    In Mavericks: Nothing to do! (so far)
    APPLE: "You" make WRONG design decisions, "you" make professional users spend dozens of hours investigating how to tweak basic features behind the scenes. And THEN, "you" quietly invalidate those changes. Please, the best design decision that "you" could make is to give the user more choice. Please, give us a section in Preferences where these things may be changed. The religious dumbing down of the interface in favour of supposedly clean esthetics is plain WRONG.
    It is also quite unacceptable that APPLE does read these pages but never responds.

    Hi,
    You don’t install VS2010 on the client PC, then where did the Form Invoice not work? When you run it from another version of VS? Or when you run the application with application.exe?
    Based on your description, one form works well, another form does not. I assume that two forms are in two different projects, then please check the .Net Framework used by the two projects. If they are different, you can use the
    one used by the Form contact for Form Invoice.
    Because this issue is a project issue, I recommend you to consult it on some application forum such as Windows Forms General forum for better support.
    VS General Question forum mainly discusses
    the usage of Visual Studio IDE such as
    WPF & SL designer, Visual Studio Guidance Automation Toolkit, Developer Documentation and Help
    System and Visual Studio Editor.
    Thanks,

  • Seagate 2TB HD not working after installing Mavericks

    Aproximity 3 weeks after installing Mavericks my 2TB Seagate HD could not be detected on my desktop
    I've read several articles stating other user's have the same problem, some articles mentioned that the HD
    is damaged and should be re-formatted, others need there data now and there unable to retrieve it.
    This is what I ended up doing since re-formatting my HD is out of the question since a fix for this issue
    will eventually come.  I simply connected my HD to my Apple Airport Extreme Modem and it connected
    perfectly over my home network. I was able to retrieve data without any problems, sure beats the other
    options I've read. DO NOT RE-FORMAT YOUR DRIVE!!!

    This seemed to be a temporary symptom. Its working now. I have 2 thunderbolt adapter, so I plug in the 2.5inch adapter and it worked. Afterwhich, I eject the 2.5 inch adapter and tried the 3.5 GoFlex Desktop Thunderbolt adapter, and it worked. The above post on the Seagate thunderbolt drive was for the 3.5inch Desktop Thunderbolt adapter.

  • ITunes not working after installing Mavericks

    I cannot open i.tunes after installing Mavericks. I cannot unistalled it either (to reinstall it) since a window appears saying it cannot be dropped or changed in any way. Thank you for your help.

    1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve your problem.
    2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
    3. Below are instructions to run a UNIX shell script, a type of program. All it does is to gather information about the state of your computer. That information goes nowhere unless you choose to share it on this page. However, you should be cautious about running any kind of program (not just a shell script) at the request of a stranger on a public message board. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them.
    Here's a summary of what you need to do: Copy a line of text from this web page into the window of another application. Wait for the script to run. It usually takes a couple of minutes. Then paste the results, which will have been copied automatically, back into a reply on this page. The sequence is: copy, paste, wait, paste again. Details follow.
    4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
    5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply.
    6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking  anywhere in the line. The whole line will highlight, though you may not see all of it in your browser, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
    Triple-click anywhere in the line of text below on this page to select it:

    Copy the selected text to the Clipboard by pressing the key combination command-C.
    7. Launch the built-in Terminal application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
    When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign ($) or a percent sign (%). If you get the percent sign, enter
    exec sh
    in the window and press return. You should then get a new line ending in a dollar sign.
    Click anywhere in the Terminal window and paste (command-V). The text you pasted should vanish immediately. If it doesn't, press the return key.
    If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know your password, or if you prefer not to enter it, just press return three times at the password prompt.
    If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that takes administrator privileges.
    The test may take up to a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line "[Process completed]" to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report your results. No harm will be done.
    8. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
    If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
    When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If it happens, please post the test results on Pastebin, then post a link here to the page you created.
    Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

  • External Hard Drive not working after installing mavericks

    After installing mavericks, I hooked up my external hard drive,
    and it would not show up on the computer.  Tried checking if

  • Time Machine does not work after installing mavericks

    After I installed maverick on my imac, my time machine backups don't work anymore!!!!
    I have a normal portable HDD attached to my Imac with time capsule backup from before mavericks was installed.
    I also has a Buffalo NAS as a second Time Machine Backup. 
    TIme capsule does not recognise my Buffalo NAS and tells me that it is not available.  It has previous backups from Mountain Lion for sure!
    My portable HDD keeps saying "Preparing for backup" for eternity.
    Please, APPLE, what is going on with mavericks?  Regretted upgrading.
    My backup is 31 days behind because of this!  Unacceptable!
    But what is strange is that I can connect to my portable HDD and Buffalo NAS as a drive.   What I have been doing is to copy and paste the important stuff into the drives.  But it really defeats the purpose of time machine, right?

    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.
