iTunes cannot be opened while it is being updated

I use an iMac and upgraded to El Capitan version 10.11.1 a month ago.  Now when I select iTunes I get a box that says "iTunes cannot be opened while it is being updated" (and your only option is to press OK).  This message is constant and never changed.  I tried a week ago, abandoned and now have tried several times throughout the day.  Same thing all day.  I had a similar problem with the photo after the upgrade and it just started working unexpectedly several weeks after the update.

Any suggestions?

Thank you!

Good morning funcourt,

The first thing I would say to you receive the iTunes error message would be to upgrade your OS X to the latest version, which is the OS X 10.11.2.

Download update of OS X El Capitan 10.11.2 Combo

Another common troubleshooting step would be to start your computer in Mode safe

OS X El Capitan: start in safe mode

Start in safe mode can help you diagnose problems you're having with your Mac.

Important: To print these instructions, click the Share button in the Help window, and then choose print.

  1. Choose the Apple menu > shut down.

  2. After your Mac stops, wait 10 seconds, then press the power button.

  3. As soon as you hear the startup tone, hold down the SHIFT key.

    You must press the SHIFT key as soon as possible once you hear the startup tone, but not before.

  4. Release the SHIFT key when you see the gray Apple logo and progress indicator.

To exit safe mode, restart your Mac, but no press during the startup.

Boot into single user mode

If these two steps do not resolve your issue, try to create a new account to isolate if the problem is with your user account or if it is the scale of the system.

How to test a question in another account on your Mac.

How to test with another user account

You can find out if unexpected behavior is related to the user file or a parameter in trying to reproduce the problem to a different user account. This process includes creating a new user account, connect to it and test for the issue.

Create a test user account

  1. In the Apple menu, choose System Preferences.
  2. Click the users and groups in the System Preferences window.
  3. Click the lock icon and enter an administrator name and password.
  4. Click on the button Add (+) below the list of users.
  5. Choose a type of user in the new pop-up menu.
  6. Give the user a name and first name, account name, and password.
  7. Click OK.
  8. Close the System Preferences window.

If there are documents from your user account that you want to test with original, place a copy of these items in the shared folder in the users folder. Press the Option key while dragging a file in this folder to create a copy.

Connect to the test user account

Log out of your current user account by choosing logout in the Apple menu, and then open a session the new account that you created. If you are prompted to login with your iCloud or Apple ID account when you log in, skip this step.

Try to reproduce the problem

Try the same steps that caused the unexpected behavior to appear. For example, if you are unable to print, try printing from this user account. If you were unable to connect to the Internet, try to navigate on a website of this user account.

If you use specific test settings depends on (for example using a specific e-mail account or an account iCloud) implemented the same test user account. For email and other parameters, you can use the Internet accounts pane in system preferences to set up these types of accounts. If your home folder files are necessary for tests, copy them into the shared folder in the users folder (/ Users/Shared). After you connect as a user test, copy these items to the same location in the test user home folder to test with.

If a problem occurs in account only one user

Is using the same steps in a user account test does not cause the same unexpected behavior, most likely you don't need to reinstall applications or OS X.

  • If a problem occurs only in a single application, check the documentation or Web site for instructions on troubleshooting specific preferences or the definition of the application files.
  • If you need help with a problem or a specific alert message, search the Apple support Web site for the text of the alert message you see.

If a problem occurs in more than one user account

If the same unexpected behavior occurs in more than one user account on your Mac, try checking for software or hardware problems.

Once you have finished

When you are finished testing, disconnect from the test account by choosing logout in the Apple menu. Then, connect to your original user account.

You can Remove the account to test user created when you are finished. Make sure you're completely finished stable, and you don't need the files or settings you have created or copied there until you delete it.

Get help

If you need assistance with a problem software or hardware, Please contact Apple technical support. If you are working with a consultant, engineering or service provider to resolve a problem, remember to mention all the steps you have already tried and the results. Also mention the alert messages that you saw in the context of the question. You can take a screenshot of all the messages that appear to refer to it later.

    Please read this message before doing anything.

    This procedure is a test, not a solution. Don't be disappointed when you find that nothing has changed after you complete it.

    Step 1

    The goal of this step is to determine if the problem is localized to your user account.

    Select the feedback connections* and log in as a guest. Do not use the Safari connection only 'user comments' created by 'find my Mac '.

    While signed in as a guest, you will have access to your documents or settings. Applications will behave as if you use them for the first time. Do not be alarmed by this behavior; It's normal. If you need any password or other personal information in order to complete the test, save, print, or write them before you start.

    Test while signed in as a guest. Same problem?

    After testing, log on to the guest account and in your own account, disable it if you wish. The files that you created in the guest account will be automatically deleted when you log out of it.

    * Note: If you have enabled 'find my Mac' or FileVault, then you cannot activate the guest account. The login 'User comments' created by 'Find my Mac' is not the same. Create a new account to test and delete it, including his home folder, after testing.

    Step 2

    The goal of this step is to determine if the problem is caused by changes in the system of third party that load automatically at startup or logon, by a device, by a police conflict or corruption of system files or some system caches.

    Please take this step regardless of the results of step 1.

    Disconnect all devices wired except those required to test and remove all the expansion cards from secondary market, as appropriate. Start in safe mode and log on to the account of the problem.

    Note: If FileVault is enabled in OS X 10.9 or an earlier version, or if a firmware password is defined, or if the boot volume is a software RAID, you can not do this. Ask for additional instructions.

    Safe mode is much slower to boot and run as normal, with limited graphics performance, and some things work at all, including an audio output and a Wi - Fi connection on some models. The next normal boot can also be a bit slow.

    The login screen is displayed even if you normally connect automatically. You need your password to log on. If you have forgotten the password, you will have to reset it before you begin.

    Test in safe mode. Same problem?

    After testing, restart as usual (not in safe mode) and make sure you always have the problem. View the results of steps 1 and 2.

  • iTunes crashes when opening since the last iso update

    Updated my iso software a few weeks ago.  Since then, whenever I try to open itunes, it crashes and gives the following error: any suggestions on how to solve this problem?  Impossible to get in itunes at all.  Tried to start if not connected to internet/wifi etc as suggested by apple.  not good. didn't want to go that the uninstall/reinstall route until I was sure it was necessary.  Thanks in advance for your suggestions.

    For general advice, see troubleshooting problems with iTunes for Windows updates.

    The steps described in the second case are a guide to remove everything related to iTunes and then rebuild what is often a good starting point, unless the symptoms indicate a more specific approach. Review other cases and a list of documents to support further down the page, in which case one of them applies.

    More information area has direct links with the current and recent if you have problems to download, need to revert to a previous version or try the version iTunes for Windows (64-bit-for old video cards) as a workaround for the problems of performance or compatibility with third-party software.

    Your library must be affected by these measures, but it is also related to backup and recovery advice if necessary.

    Hi JeffinAptos,

    Looks like your iTunes app becomes unresponsive and make your Mac does not respond as well. You can try to update your OS X by installing the update found here combo. Update of OS X El Capitan 10.11.6 Combo

    If the problem is persistent after update to OS X, it's the iTunes app to relocate by downloading a new copy at this link. Download iTunes

    I am sure that these procedures will have your iTunes app run correctly without delay.
    Please use the Apple Support communities to post your question. Have a wonderful day.

  • How is it, iTunes cannot find my Installer 6464msi to finish the update?

    I tried to update. I tried to uninstall/reinstall. For about six months now, my iTunes cannot locate the required package (iTunes, 6464msi).

    I can easily locate in my downloads. I have same open it and run from the download files. But at the end of the update process and read error happens with all methods, which reads:

    The feature you are trying to use is on a network unavailable resource.

    Click OK to try again or enter a different path to the folder containing the installation package iTunes6464msi.

    (Browse)

    Even if I try to use 'Browse' to access my downloads, installation package does not appear. And if I click OK to try again, the result is the same (see above).

    This has happened when I had Windows 7 and always with my upgrade of Windows 10.

    The members of the Forum Pro first - Hello


    Can someone out there describe in simple basic procedure, how a first time user start using Premiere Pro to the layer just a moving figure video of 5 minutes (a friend aerial artist model with white moving belt in silk on a rest mainly black background layer and a change to a night sky stars panorama I photographed previously?)

    I know that this can easily be done, I have worked in thousands of still images with creative cloud for previous years, but not yet in video in Premiere Pro, so thanks for any advice.

    I enclose the actual video that I use and some samples of the fields of the night sky that I photographed recently for ideas

    I intend to make possibly more elaborate, but for now if anyone of you could just show the basic commands and menus/menus to start to do it simply and quickly. Maybe how to most later convert it tone black & white or sepia. The ideas here is to recreate a sequence modern suite of familiar German Film, wings of desire. Perhaps also a progression in the future to create an effect of the night sky very slowly turning into one layer background behind the main façade first video layer in normal movement. Then maybe a little further - how to adjust the speed of the front to a path layer more slow half price while keeping the substantive motion, the original speed. (* although I realize that I didn't do in 64 fps for the slow movement, I am not concerned about that and would actually welcome a light old world "flip effect framework" as if, in appearance of the films more former silent motion.) * In addition, possibly cutting on 'dead time' a few seconds at the beginning of the video and the 2nd or 3rd time for a few seconds of this unexpected error, when the silk scarf fell on the camera lens (without changing the audio timeline?)

  • Damaged files Adobe Muse site and cannot be opened

    Hello

    I designed my first site on Adobe Muse.

    However, when I tried to open the file to continue designing, a message popped up saying "damaged files Adobe Muse site and cannot be opened.

    I read the previous discussions on the same issue:

    -The file is stored on my mac, not synchronized Dropbox or any other software.

    -I have not yet published the site.

    -My machine did however turn off due to load shedding while the application of the Muse was open (but not the file). Would this have something to do with it?

    Is it possible to recover the site?

  • Cannot open the 5.3 Lightroom Catalog. Download «...» It is not writable and cannot be opened"message.

    Hello world

    I'm having a problem opening a lightroom catalog. I get a message "Lightroom can't use the catalog because it is not writable and cannot be opened.

    The catalogue and thousands of RAW files are stored on an external drive.

    Here are the steps that caused the problem in my view:

    1 has worked with the catalog on my laptop. Disconnected the disk without closing first Lightroom (big mistake).

    2 connect the external hard drive on desktop PC and did extra work. Closed Ligtroom (office) and disconnected the disk.

    3 reconnect the drive of the laptop while original catalogue is always open (see #1 above). Clicked on an image at which point Lightroom crashed and closed by itself.

    The problem now is that the catalog opens is no longer on computers. Any attempt to open the results in the message "Lightroom can't use the catalog because it is not writable and cannot be opened. There is no lock or log file that can be deleted, just the lrcat file and tons of files with preview of the data.

    I hope this isn't a lost cause and I can still recover the catalog. There are 2 work days.

    Thanks in advance for any help/advice!

    Ok. I found a solution. As Ligthroom catalog is a SQLite database, you can use a database tool to fix it. Just download SQLite www.sqlite.org for your OS (Windows 7 in my case) and unzip into C:\SQLite for ease of use. Copy your catalog corrupted the C:\SQLite file as well as to keep things simple.

    At the command prompt start > run, type 'cmd' and press ENTER. This opens the command prompt where you will need to run the following commands:

    1 cd sqlite

    2. echo .dump | SQLite3 yourcatalogfilename.lrcat > tempcatalog.sql

    3 sqlite3 - init tempcatalog.sql newcatalogfilename.lrcat

    After the execution of line 3, you may or may not see error messages. No worries, it simply truncated faulty records that is what causes the catalog to crash.

    Now, copy the newcatalogfilename.lrcat into your lightroom catalog file and run it. You should be able to get things up and running to where you left, or to the point where original Lightroom Catalog has been corrupted in first place.

    I hope this helps. It took me a few hours to find a solution, but it saved me at least 2 days of work. Original credit goes to the author of the article according to http://www.simplyness.com/more-photography-tips/recover-corrupted-unrepairable-lightroom-3 - catalog - with - sqlite.html. It seemed to have worked for Lightroom 3 and still worked for Lightroom 5.3 in my case.

  • "The project seems damaged, it cannot be opened.

    Well, any help would be apporeciated.

    Thank you

    Welcome to the forums.

    The error massaage indicates this project file is either damage or damaged.

    If the project file is very good project file can run on simple subscription App and subscription Volume License.

    Just make sure that you open project created in first pro CS6 not project created in CC pro first.

    Project created first CC pro will not open ion first pro CS6 while vice versa is possible.
