HT201364 1 currently have iOS X Lion 10.7.4 on my MacBook Air. I have downloaded an update marked 10.7.5 but cannot intel it. an error message interrupts the installation. my final destination is OS X Maverick. what do I do to upgrade and get to Maverik

I have tried several times to upgrade from iOS X Lion 10.7.4 to 10.7.5 without luck. Installation stops halfway with an error message. So, I cannot migrate to Maverick. What do I do?

You do not need the Lion 10.7.5 update. Just download and install Mavericks 10.9.2 direct from the App Store and install it over the top of your current version of Lion.
And don't forget to make a full backup of your system before upgrading.
Cheers
Pete

    Try deleting the photo cache from your computer and then re-try the photo sync - the location of the cache, and how to delete it, is on this page http://support.apple.com/kb/TS1314

  • My iphone 4 has an error message on the screen that reads "iphone disabled connect to itunes" what do i do

    My iPhone 4 has an error message on the screen that reads "iiPhone disabled connect to iTunes" I've tried connecting and can't get anywhere what do I do and what is the problem?

    Your phone is disabled for some reason. Maybe you entered the wrong Passcode too many times. In any case you need to do just as the phone is instructing you to do. Start the latest version of atones on your computer and connect your phone. iTunes should guide you through the process of getting your phone working again. Here's a link to an Apple support page on this:
    Forgot passcode for your iPhone, iPad, or iPod touch, or your device is disabled - Apple Support

  • How do I fix an error message during the installation of Flash on a Macbook running Mavericks?

    Hello Everyone,
    I'm getting an error message when installing Flash on my Macbook running the most current version of Mavericks.  It starts to install, then says "Could not complete installation" and the only option that I have to quit the installation.  I have closed all other applications, so I'm at a loss as to what is causing this problem.  Please assist.
    Thanks!

    Download the FULL offline installer here: Flash Player 12.0.0.70 (Mac OS X)
    Save it (Download Linked File as) and Quit Safari.
    Double click the saved file and "mount the DMG" on your desktop.
    A window will open with the installer - DO NOT RUN the installer from here!
    Right click it or Ctrl+click it and "Show Package Contents"
    In Contents/Resources, double click the Adobe Flash Player.pkg
    A "COCOA" Installer will open.
    Folow the instructions to install Flash Player from there.
    Then eject the DMG and you're all done.

  • I have photoshop 7.0 which has stopped working on my computer. When I try to open an image in Photoshop it gives me an error message saying the image is damaged or corrupted. I can open the same image in other image programs.

    Can anyone help me. I have tried uninstalling it and reinstalling it but nothing helps. I can not afford to spend money on a new program.

    First step: update Photoshop to 7.0.1.
    Second step:  provide sensible information:
    BOILERPLATE TEXT:
    Note that this is boilerplate text.
    If you give complete and detailed information about your setup and the issue at hand,
    such as your platform (Mac or Win),
    exact versions of your OS, of Photoshop (not just "CS6", but something like CS6v.13.0.6) and of Bridge,
    your settings in Photoshop > Preference > Performance
    the type of file you were working on,
    machine specs, such as total installed RAM, scratch file HDs, total available HD space, video card specs, including total VRAM installed,
    what troubleshooting steps you have taken so far,
    what error message(s) you receive,
    if having issues opening raw files also the exact camera make and model that generated them,
    if you're having printing issues, indicate the exact make and model of your printer, paper size, image dimensions in pixels (so many pixels wide by so many pixels high). if going through a RIP, specify that too.
    A screen shot of your settings or of the image could be very helpful too,
    etc.,
    someone may be able to help you (not necessarily this poster, who is not a Windows user).
    Please read this FAQ for advice on how to ask your questions correctly for quicker and better answers:

  • I bought the new ipad (ipad 3) in July 2012.  what software did it come with and does it have siri?

    i bought the new ipad (ipad 3) in July 2012.  what software did it come with and does it have siri?

    The new iPad comes with iOS 5.1.1.
    To get all new functionality and Siri, you need to update to iOS 6.
    Be aware that if you were a Google Maps App user this has been replaced by version 1.0 of Apple's own new Maps App.
    From the many user reviews, Apple's Map App is still a work in progress.
    You can still access Google Maps from the Safari web browser.
    Also, the YouTube app has, also, made a disappearing act.
    You can use mobile YouTube from Safari to still view YouTube or a YouTube client app called Jasmine or download the Google YouTube App for iPhone. Google is working on a new YouTube App for iPad and isn't available, as yet.

    Hello Bruarong,
    It sounds like you are unable to print to your printer from Mac OS X Lion. I recommend the troublehsooting from the article named:
    Troubleshooting printer issues in OS X
    http://support.apple.com/kb/ts3147
    Follow these steps until the issue is addressed:
    Make sure that the printer is powered on, has ink / toner, and that there are no alerts on the printer’s control panel. Note: If you cannot clear an alert on the printer's control panel, stop here and check the printer's documentation or contact the manufacturer for support.
    Ensure the printer is properly connected to a USB port on the Mac or AirPort base station / Time Capsule. If the printer is a network-capable printer, make sure that it is properly connected to your home network.
    Use Software Update to find and install the latest available updates. If an update is installed, see if the issue persists.
    Open the Print & Scan pane or Print & Fax (Snow Leopard) pane in System Preferences.
    Delete the affected printer, then add the printer again.
    If the issue persists, try these additional steps:
    Reset the printing system, then add the printer again.
    If the issue still persists, reset the printing system again.  Download and install your printer's drivers. Then, add the printer again.
    Contact the printer vendor or visit their website for further assistance.
    Thank you for using Apple Support Communities.
    Take care,
    Sterling

  • HT1414 I am trying to restore my Ipod touch 5 generation but I am receiving an error message that says  your Ipod can not be restored you need your password I don't know my password so I don't know what to do. I have started the procedures 3 times but no

    If it is asking for the screen-lock passcode then:
    Place the iOS device in Recovery Mode and then connect to your computer and restore via iTunes. The iPod will be erased.
    iOS: Wrong passcode results in red disabled screen                         
    If recovery mode does not work try DFU mode.                        
    How to put iPod touch / iPhone into DFU mode « Karthik's scribblings        
    For how to restore:
    iTunes: Restoring iOS software
    To restore from backup see:
    iOS: Back up and restore your iOS device with iCloud or iTunes
    If you restore from iCloud backup the apps will be automatically downloaded. If you restore from iTunes backup the apps and music have to be in the iTunes library since synced media like apps and music are not included in the backup of the iOS device that iTunes makes.
    You can redownload most iTunes purchases by:
    Downloading past purchases from the App Store, iBookstore, and iTunes Store        
    If problem what happens or does not happen and when in the instructions? When you successfully get the iPod in recovery mode and connect to computer iTunes should say it found an iPod in recovery mode.
    Otherwise follow varjak paw recommendation

    I am trying to re-install Photoshop CS6. The files have downloaded but I get and error message that the Adobe Support Advisor is required to determine what the installation probIem is. I click on the link that says "get the Support Advisor here only to be told the Support Advisor no longer exists!! A blind loop. I need to have Photoshop CS6 installed...what do I do from here??

    The CC Cleaner Tool assumes the Akamai Download Manager is activated and it has not. It seems to be the missing file that triggers the error message. \in a previous re-install I was prompted to download & install the Akamai Download Manger, but not this time. Is there somewhere on the Adobe website that I can download it??
