The screen resolution in 1920x1200 dropped on my MacBook Pro 17". Seems like I have not the same pixels. There are also vertical, thin lines on the screen. Makes the screen look milky. Anybody knows what's going on and how to fix it?

Take it to an Apple Store or other service provider for testing.

  • Firefox is refusing to start. It says that my profile is missing, which it appears to be. Yet the way in which one goes about creating a new profile wont' work either. Anybody have a bloody clue what's going on and how to fix it?

    AIR give you classes to detect an on-line or off-line status, it's in 
    this way for the sake of flexibility for instance what happens if you 
    only what to sync  data only on Saturdays at 2 am? If it were done 
    automatically that'll be a problem. And it isn't so complicated.
    You can download the SalesBuilder from AIR examples at www.adobe.com/devnet/air
      it's an application that does everything you have in mind.
    I don't understand your question abou file types.
    An AIR app can communicate with almost every backend served tech 
    CF, .Net, PHP, RoR.
    Sincerely,
    Michael

    Sorry but I don't quiet understand. I thought AIR did the updating 
    automatically? I didn't realise the developer had to program the 
    logic of how the updates take place?  Is it a case in most AIR apps 
    that when online the app updates the server and once every intervel 
    (of however long) the local SQLite DB is synced to the more updated 
    server DB. Then when offline the developer has to sense that the app 
    is offline and store a log manually of the updates without any help 
    from AIR itself, and then update once it comes online again?
    >
    Can AIR link to anything more than a database on the server side 
    apart from webservices, for example .as files or any other file types?
    >
    What type of server is a Flex app stored on, is it a specific Adobe 
    server rather than a Java or .NET server?

    Thank you so much for your last comment!

  • I have 100  songs on i pod touch. But when i connect it to itunes it only showed 44 songs. What is actually happening and how to fix the problem so that all music in my iphone can be seen in my itunes

    I have 100  songs on i pod touch. But when i connect it to itunes it only showed 44 songs. What is actually happening and how to fix the problem so that all music in my iphone can be seen in my itune

    If they are iTunes purchased music then go to Settings>iTunes and App Store and turn off Show All.
    Next
    Try:
    - Reset the iOS device. Nothing will be lost      
    Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Unsync/delete all music and resync
    To delete all music go to Settings>General>Usage>Storage>Music>Tap edit in upper right and then tap the minus sign by All Music
    - Reset all settings                            
    Go to Settings > General > Reset and tap Reset All Settings.
    All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
    - Restore from backup. See:                                               
    iOS: Back up and restore your iOS device with iCloud or iTunes
    - Restore to factory settings/new iOS device.

  • Whenever I try to use my macbook, it will work for about 10 min. then the screen will go black, the computer will not respond to my commands, and I have to restart it. Can anyone tell me what's going on, and how to fix it? Thank you!!!

    Hello everyone, like most people on this site, I am having difficulties understanding and fixing my Macbook Pro. About a month ago my computer screen went black, the computer was unresponsive, and it started making a beeping noise. I restarted the computer, and it seemed to have fixed itself. 6 days ago, I put my laptop into it's case with some papers, went home (about 30 min. after putting laptop into case), and opened my bag. My computer's fans were on, the computer was really hot, and when I opened the computer, the screen was black and unresponsive. I turned it off, let it cool down, turned it back on, started to stream a video on Hulu, and about ten minutes after, the screen went black again and the computer was unresponsive. Now everytime I turn it on after about ten to fifteen minutes the screen will go black, the computer will become unresponsive, and I have to shut it off. The weird thing though is that everytime I restart my computer, when I reopen my account, my computer acts as if nothing has happened, and everything I had opened or unsaved is still there without autosave saving the documents.The screen also goes black and the computer becomes unresposive when I move the computer around. I get a lot of pop-up ads and other crap on my computer when I am on the internet. I don't know if one of those pop-up websites might have given me a virus or may be the cause of this problem. I don't now what is wrong with my computer or how to fix it, but if anyone has any advice, I WOULD GREATLY APPRECIATE IT!!!!!!! Thank you very much!!!
    -- Sincerely, A very confused, scared, and hopless Macbok Owner

    To get rid of "pop-up ads and other crap on my computer when I am on the internet", click on Safari in the Menu bar, and select Preferences. Next select Extensions. Delete all of them. Restart Safari.
    The first step in addressing the black screen is an SMC reset.
    Shut down the computer.
    Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
    On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
    Release all the keys and the power button at the same time.
    Press the power button to turn on the computer. 
    Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

  • I have several tabs open, and today when I went online some of them loaded my ISPs homepage instead of the sites that were supposed to be there. Any ideas what's going on and how to fix it?

    The back/forward navigation buttons are greyed out, and I can't find the sites under the History tab. Actually at first all of the tabs loaded my ISPs homepage, some of them had the Back button active and some didn't. I'm wondering how to get the latter back to the pages they're supposed to be on.

    That combination of problems points to a possible issue with the file that stores history and bookmarks. See http://kb.mozillazine.org/Locked_or_damaged_places.sqlite

  • HT1349 I just got iPad 3 and I am trying to download all app to my iPad it takes forever and for the one that finish downloading, it won't work when i tap on it. Anybody knows what is going on?

    I have ipad2 and just got iPad 3 so I try to download all purchased apps to my new iPad but it takes forever and all apps that downloaded are not working, I already restore my old iPad to give it my little girl. Anybody knows what is going on and how cani fix this to have all of my apps to my new iPad. Thank you for reading my question .

    Try a Reset [Hold the Home and Sleep/Wake buttons down together for 10 seconds or so (until the Apple logo appears) and then release. When the screen goes blank then power ON again in the normal way.] It is absolutely safe.
    Also try downloading another free app and then try again.

    Same problem for me.
    1. Cannot connect to wifi as icloud password pop up keeps appearing.
    2. tried deleting account. UNable to do so.
    3. tried resetting password by logging into apple id through desktop as mentioned in one of the responses in another thread. Unfortunately the apple id to be reset is the same as being prompted by icloud and hence unable to reset the same.
    Feel like breaking the **** ipad into bits. Stupid of apple to let such a bug in and not offer support !!

  • Firefox update installs, but does not apprearon screen, or task manger yet is running what is going on and how does one fix it?

    I installed the update Mozilla Firefox 28. It was suppose to launch upon completion. it did not appear on the monitor screen, nor the task manager, but was running; for when I attempted to install the older version again it, it said that Firefox was running and needed to be turned off.
    I restarted the computer and tried opening Firefox, with the same results.
    After restarting again, I attempted to reinstall the update, with the same results taking place.
    I attempted to uninstall Firefox and install the new version. The same results took place.
    In the past, I could install Firefox 27 update, only now I can't for the same thing takes place. Past a certain version (19), this event takes place, but 19 and older can install it with no problems.
    I checked Firefox troubleshooting information. All was normal. I checked my firewall. Again, all was normal. Tried Firefox reset. Did not help. Tried with my firewall disabled. Did not solve the problem.
    Ran a virus check (deep) no viruses. Checked my computer system. No errors.
    I can install updates for my other programs, even install new programs; just not Firefox.
    What is going on and how does one fix it.

    Hi Amseeking,
    Thank you for your question. From your description, you tried to install the 28 update from a version 19 installation. Did you install a fresh install of 28 successfully? Where the name of the file is"Firefox Setup Stub 28.exe"? This is what is sound like happened. When going to about Firefox and searching for updates it installs over the current installation. However if Firefox was already running, there are more than one installation.
    Updating from version 19 to 28 would not be a problem. However the user data from your previous version would have to be imported to the new installation if you have more than one install on that computer.
    An easy way to tell is to search for Firefox in the Start menu to see if more than one icon shows up in the search results.
    I hope this helps.
