Thank you

Try an SMC reset, which can often fix that:  http://support.apple.com/kb/HT3964 . Note as you scroll down, there are two sets of directions for MacBooks, depending on whether you can remove the battery or not.

    1. iTunes 10 for Mac- Update and restore software on iPod, iPhone, or iPad
    2. iPhone, iPad, iPod touch: Wrong passcode results in red disabled screen
    3. iOS- Understanding passcodes
    4. What to Do If You've Forgotten Your iPhone's Passcode
    5. How to Recover Forgotten iPhone Restrictions Passcode | The iPhone and iPad
         If you have forgotten your Restrictions code, then follow the instructions
         below but DO NOT restore any previous backup. If you do then you will
         simply be restoring the old Restrictions code you have forgotten. This
         same warning applies if you need to restore a clean system.
    A Complete Guide to Restore or Recover Your iDevice (if You Forget Your Passcode)
    If you need to restore your device or ff you cannot remember the passcode, then you will need to restore your device using the computer with which you last synced it. This allows you to reset your passcode and re-sync the data from the device (or restore from a backup). If you restore on a different computer that was never synced with the device, you will be able to unlock the device for use and remove the passcode, but your data will not be present. Refer to Updating and restoring iPhone, iPad and iPod touch software.
    Try restoring the iOS device if backing up and erasing all content and settings doesn't resolve the issue. Using iTunes to restore iOS devices is part of standard isolation troubleshooting. Restoring your device will delete all data and content, including songs, videos, contacts, photos, and calendar information, and will restore all settings to their factory condition.
    Before restoring your iOS device, Apple recommends that you either sync with iTunes to transfer any purchases you have made, or back up new data (data acquired after your last sync). If you have movie rentals on the device, see iTunes Store movie rental usage rights in the United States before restoring.
    Follow these steps to restore your device:
         1. Verify that you are using the latest version of iTunes before attempting to update.
         2. Connect your device to your computer.
         3. Select your iPhone, iPad, or iPod touch when it appears in iTunes under Devices.
         4. Select the Summary tab.
         5. Select the Restore option.
         6. When prompted to back up your settings before restoring, select the
              Back Up option. If you have just backed up the device, it is not necessary
              to create another.
         7. Select the Restore option when iTunes prompts you (as long as you've backed up,
             you should not have to worry about restoring your iOS device).
         8. When the restore process has completed, the device restarts and displays the Apple
             logo while starting up:
               After a restore, the iOS device displays the "Connect to iTunes" screen. For updating
              to iOS 5 or later, follow the steps in the iOS Setup Assistant. For earlier versions of
              iOS, keep your device connected until the "Connect to iTunes" screen goes away or
              you see "iPhone is activated."
         9. The final step is to restore your device from a previous backup. If you do not have a
              backup to restore or have forgotten your restrictions passcode, then restore as New.
    If you are restoring to fix a forgotten Restrictions Code or as a New device, then skip Step 9 and restore as New.

  • My daughters friend changed her password on her ipod touch and doesn't remember what the password is... and when she guesses and its wrong, it disables the ipod.  Does anyone know how to fix this??

    My daughters friend changed her password on her ipod touch and can't remember the password and when she guesses and gets it wrong, it disables her ipod.  Does anyone know how to fix this problem??

    You'll need to connect it to the iTunes library you normally sync it with and restore it.  If iTunes asks you for this passcode before it will let you proceed, connect the iPod to iTunes in recovery mode instead using the instructions in this Apple support document.

  • I am using imovie 09 and when I try to play the scenes from my hd camcorder video freezes then voice freezes and bar keeps running to the end.  Does anyone know how to fix this? PLEASE!

    I am using imovie 09 and when I try to play the scenes from my hd camcorder the video freezes then audio freezes and the play bar keeps going with no video or audio.  How Can I fix this???  PLEASE HELP!

    Up front I would say the short answer is "no"... but the long answer is "sort of".
    Replicators are part of the Fractal "arsenal" and Motion definitely has those, but I think you would be very hard pressed to come anywhere near the type of fractal imaging as in the Electric Sheep example.
    I was able to squeeze the following out of Motion (the base element is a simple square), but by the time it got this far, Motion wouldn't play faster than about 1 frame every 5 or so seconds. At a certain point, you end up having to render movie files in order to see it in action (and that took Motion about 8 minutes for a 12 second project [09 iMac i7].) [If you're interested, I posted a short video of these here: http://www.youtube.com/watch?v=l6Fe_ydfAss. The segments are longer than 12 seconds each because these are designed to loop @12 seconds and each one was looped more than once.]
    [You asked the question on the 4th - I "finished" this on the 7th... (I admit to several "false starts")]
    If you have a faster mac than mine, you might be able to do more than this... and you really don't have access to the Maths that fractal apps have, so depending on your creativity for devising the "root" motif element you may (or may not) be disappointed in what Motion has to offer (it *will* try your patience!) If you would like to experiment anyway, I will explain some of the techniques I used for the above (which are, at best, rudimentary!) Once you get the basics down, you should be able to take off in your own directions.

  • My new iphone 4 does not have any sound when recording a video with the camera app.  Does anyone know how to fix this?

    I just got a new white iphone 4.  When I try to take a video using the camera app, there is only a muffled sound.  I never had this problem with my old iphone.  I tried to restore it and that didn't help.  I checked over all of the settings.  Does anyone know how to fix this??  Thanks for any help you can offer!

    There is a good possibility that your trimming of the SIM card could have damaged it some way. If the SIM was working in the old phone, then you cut it and the first new phone didn't work and now this phone doesn't work, it leads me to believe it has to do with the SIM card or the account. You are sure there is no problem with the account. Did you check with the provider when you got the iPhone 4 to make sure there was no problem with the account when you could not send or receive SMS? Why can't you just get a micro-sim? The iPhone should have come with one when you purchased it.The iPhone 4 is designed for a micro-sim. I don't believe this is a hardware problem unless the phone has been hacked or modified in some manner.

    You have to delete the corrupt back-up so iTunes can at least back-up the current data on the iPhone and then restore it. Search these forums, there a several good posts on how to delete the corrupt back-up.

  • I recently bought an Epson Artisan 837 printer. I installed the driver and now Photoshop from CS3 will not open. It quits when the Twain portion of the program starts loading. Does anyone know how to fix this so my printer will work with Photoshop??

    I recently bought an Epson Artisan 837 printer. I installed the driver and now Photoshop from CS3 will not open. It closes every time it gets to the point where it is loading the Twain portion. Does anyone know how to fix this so my printer and Photoshop will work together? Thanks for any help I can get!

    You're welcome. 
    But, no, don't look to  Epson for fixes to their  driver in newer versions, and Adobe has deprecated the TWAIN plug-in.  Hoping for a solution there is futile.  That has not happened and it's never going to happen.  The consensus is that it's pretty foolish to tie up Photoshop to scan.  Honestly.
    Any improvement in the behavior of newer versions of the Epson drivers in that regard would be pure coincidence.
    You need to understand that you never, ever scan "within" Photoshop, as Photoshop has no scanning capabilities whatsoever.  When you use the Import > Twain plug-in all you are doing is blocking Photoshop while you call up the stand-alone Epson scanning software.  If you think about it, its most inefficient.
    VueScan has a pretty powerful scanning plug-in that can be called from the Impost menu—if you insist.  VueScan is not free, but it's a pretty good value, IMO.
    As for the Epson CD printing software, I have no clue.  Sorry.

    Hey terremo,
    Thanks for the question. From the information you provided, it sounds like the iMac is successfully turning on, however video is not displayed. These symptoms can usually be isolated further by the troubleshooting steps in this article:

  • My keyboard is no longer lighting up on my macbook pro...does anyone know how to fix this issue manually?

    My backlight on my macbook pro unibody is not working. The lights do not come on. Does anyone know how to fix this manually? Im also missing screes to the back of my computer holding it in shape. My battery needs to be replaced as well. How do i do all of this? Id also like to replace my RAM.

    For the keyboard backlight:
    Have you tried pressing the "lights on" F-key, that has like a half-round rays of light over a bar symbol (currently F6 on my Mac, but may be different on other models)? If it doesn't work, does anything show on the screen?
    If a crossed-out symbol pops up onscreen when you press the F-key, that means that automatic keyboard lighting is enabled and the Mac thinks surroundings are too bright already. Go to System Preferences / Keyboard and uncheck the "Automatically illuminate keyboard..." item, then try again.
    For the screws:
    Visit www.powerbookmedic.com or www.ifixit.com and see in their Mac parts section for a replacement screw set. You will need to know your Mac's model, printed on the bottom lid, to ensure you get the correct parts for that particular computer.
    For the RAM:
    While in either of the two places I mentioned above, visit their How-To / DIY section for instructions on how to replace RAM on your Mac. Then visit www.crucial.com, www.corsair.com, www.kingston.com, www.otherworldcomputing.com or any other RAM maker, use their RAM advisor together with your Mac's model to select the correct RAM upgrade kit for your Mac.
