Hi Sandra,
you'll need to edit the security settings to install programs 'Mac App Store and identified developers'
Open the Systems Preference and go to Security & Privacy.  There will be a section in the 'General' tab for 'Allow apps downloaded from:"  The default selection is 'Mac App Store'.  Change this setting to 'Mac App Store and identified developers".
This screenshot is taken on OS X 10.10 (Yosemite), so it may look slightly different if you're on a different OS X version.

  • ""Install Adobe Flash Player.app" can't be opened because... not downloaded from the Mac App Store"

    I jsut upgraded to 10.9 and it is up to date and also my safari is up to date (no updates available for it). My safari is saying that my flash is out of date. when I follow the links it lets me download but when I double click to install it tell me "“Install Adobe Flash Player.app” can’t be opened because it was not downloaded from the Mac App Store.". When I install the flash UNinstaller and try to install that, it tells me the same. I ALSO found the exact same problem when I tried to install the acrobat installer (some tried to download a pdf and the page told me that my acrobat reader 'might' be out of date). Any thought?

    You're running up against the GateKeeper.
    Download the offline installer: Flash Player 12.0.0.44 (Mac OS X) by right clicking and choosing "Download Linked File As".
    Mount the DMG and when it opens, right click the installer and choose "Open".
    You'll see a warning. Click "Open" again.
    It will run from there.

  • Can't open TurboTax 2013 because it was not downloaded from the App Store

    I downloaded TurboTax 2013 directly from Intuit.  When I launch it, I get the error message "This application cannot be opened because it was not downloaded from the App Store."  It was not downloaded from the App Store because the App Store doesn't have the version I need.  Now what?

    I think you should use the new version for free turbotax. I have used turbo tax 2014 recently.
    From Apple store you will defiitely get this software easily.

  • How can I avoid the message "Can't install java script because it was not downloaded from the App Store?

    I am trying to install an update for Java. The system won't allow it, saying I have specified "in Security" not to install any download not from the App Store. The only preferences pane I know of is the one on Safari, and it doesn't have anything about this. Am I looking in the wrong place? How can I get around it? I had the same trouble trying to install an Adobe Flash upgrade.

    When I use your hot link "these instructions" I get a  blank page.
    Here is the message I get on trying to install a Java Script update:
    This is frustrating in that
    the update is not available on the App store.
    it refers to security preferences I did not set and can't identify or locate--no such settings appear in Safari> security.
    Can you be more specific? Thanks.

  • I have a mac computer.  I am trying to install flash player but get the message "install adobe flash player wants to make changes.  Type your password to allow this." I do not use a password to open the computer.

    I have a mac computer that uses no password.  When installing flash player I get the message "Install adobe flash player wants to make changes  Type your password to allow this.  I can't get past this message.

    Hi,
    To change your password you will need to open System Preferences, then open Users & Groups, click on Change Password.  Change your password to a temporary one, then when you have finished you do the same procedure to change it back, by typing in the temp password then leaving the new password blank.  Hope this helps.

    When trying to install flash player update on my mac running osx 10.5.8.   I get error message "the application install adobe flash player quit unexpectedly"  I've tried uninstalling the application and restarting my computer. But when I click the install icon  it quits unexceptionally every time.
    Please help!

    Hello,
    Flash Player is no longer supported on OS X 10.5.8.  The last version to support OS X 10.5.8 is Flash Player 10.3.  Flash Player 10.3 is available for download from this page: http://helpx.adobe.com/flash-player/kb/archived-flash-player-versions.html.

  • The folder "com.apple.TCC" can't be opened because you don't have permission to see its contents.

    I've noticed a folder with a 'no access' sign on it's bottom right corner - com.apple.TCC - and when i try to open it it says "The folder “com.apple.TCC” can’t be opened because you don’t have permission to see its contents."
    Does anyone know what this is and why i can't access it? No-one else uses this macbook but me.
    Also, as of this afternoon, I can't two finger scroll on any web browser?
    Thanks.

    Back up all data.
    This procedure will unlock all your user files (not system files) and reset their ownership and access-control lists to the default. If you've set special values for those attributes on any of your files, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. Do so only after verifying that those settings didn't cause the problem. If none of this is meaningful to you, you don't need to worry about it.
    I've tested these instructions only with the Safari web browser. If you use another browser, they may not work as described.
    Step 1
    If you have more than one user account, and the one in question is not an administrator account, then temporarily promote it to administrator status in the Users & Groups preference pane. To do that, unlock the preference pane using the credentials of an administrator, check the box markedAllow user to administer this computer, then reboot. You can demote the problem account back to standard status when this step has been completed.
    Triple-click anywhere in the following line on this page to select it:
    { sudo chflags -R nouchg,nouappnd ~ $TMPDIR.. ; sudo chown -R $UID:staff ~ $_ ; sudo chmod -R u+rwX ~ $_ ; chmod -R -N ~ $_ ; } 2> /dev/null
    Copy the selected text to the Clipboard by pressing the key combination command-C.
    Launch the Terminal application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
    Paste into the Terminal window (command-V). I've tested these instructions only with the Safari web browser. If you use  another browser, you may have to press the return key after pasting.
    You'll be prompted for your login password. Nothing will be displayed when you type it. You may get a one-time warning to be careful. If you don’t have a login password, you’ll need to set one before you can run the command. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
    The command may take a few minutes to run, or perhaps longer if you have literally millions of files in your home folder. Wait for a new line ending in a dollar sign (“$”) to appear, then quit Terminal.
    Step 2 (optional)
    Take this step only if you have trouble with Step 1 or if it doesn't solve the problem.
    Boot into Recovery. When the OS X Utilities screen appears, select
    Utilities ▹ Terminal
    from the menu bar. A Terminal window will open.
    In the Terminal window, type this:
    res
    Press the tab key. The partial command you typed will automatically be completed to this:
    resetpassword
    Press return. A Reset Password window will open. You’re not going to reset a password.
    Select your boot volume ("Macintosh HD," unless you gave it a different name) if not already selected.
    Select your username from the menu labeled Select the user account if not already selected.
    Under Reset Home Directory Permissions and ACLs, click the Reset button.
    Select
     ▹ Restart
    from the menu bar.

    Hello JohnnyChin95,
    You absolutely can just reinstall OS X Mavericks without having to erase and install. The steps to do that are almost the same as the only thing you do differently is that you do not go to Disk Utility to erase the drive. Just go to the Reinstall OS X option and pick your Hard Drive and follow the on screen instructions to get it going. Check out the article below for the step by step process.

  • I have upgraded to Lion, and want to upgrade my iPhoto 8.1.2, but when I try it says it was not purchased at a MAC Apple store, which it was.  Then it asks if I want to buy 9.2.3, and I say yes. It responds with Product Distribution file can't be verified

    I have upgraded to Lion, and want to upgrade my iPhoto 8.1.2, but when I try it says it was not purchased at a MAC Apple store, which it was.  Then it asks if I want to buy 9.2.3, and I say yes. It responds with Product Distribution file can't be verified. Maybe damaged or not signed.  How do I get this fixed, so I can download the new iphoto's that are available.

    How did you move your iPhoto library to the new system?  the recommended way is Connect the two Macs together (network, firewire target mode, etc)  or use an external hard drive formed Mac OS extended (journaled) and drag the iPhoto library intact as a single entity from the old Mac to the pictures folder of the new Mac - launch iPhoto on the new mac and it will open the library and convert it as needed and you will be ready move forward.
