BUG: Open with option missing for M4A / ALAC files (OSX)

I just discovered this bug incredibly frustrating just starting to work with M4A / ALAC (Apple Lossless Audio aka) files. Right click on a such file and by going to the "Open with" menu, hearing is absent from the list. However, manually opening the same file via by dragging the icon of the hearing or the program while open, or even via the command Open Audio in Audition all work fine. These M4A files are converted directly from iTunes. This forum works hearing CC 2014.

After some research, I found out the reason why. The file Info.plist inside the Audition.app-> content file is apparently not a section of CFBundleTypeExtension for M4A files. Open that file and search for "CFBundleTypeExtensions." You will see a bunch of entries for this type. In fact, this piece of information tells OSX what file extensions/types can open hearing.

Example of the type of mp3 file:

< dict >
< key > CFBundleTypeExtensions < / key >
< table >
< string > mp3 < / string >
< / array >
< key > CFBundleTypeIconFile < / key >
< string > au_document_secondary_mp3.icns < / string >
< key > CFBundleTypeName < / key >
MP3 Audio file < string > < / string >
< key > CFBundleTypeRole < / key >
< string > editor < / string >
< / dict >

So the next logical step, I created a duplicate just below it to M4A:

< dict >
< key > CFBundleTypeExtensions < / key >
< table >
M4A < string > < / string >
< / array >
< key > CFBundleTypeIconFile < / key >
< string > au_document_secondary_m4a.icns < / string >
< key > CFBundleTypeName < / key >
Apple MPEG-4 audio < string > < / string >
< key > CFBundleTypeRole < / key >
< string > editor < / string >
< / dict >

Save the file, restart the computer or rebuild Launch Services database and restart OSX and viola, now when right click on a file M4A, hearing is an option!

What I want to know from the Adobe developers is, why is this update option missing in the menu 'Open with' first and will it be fixed for the hearing?

We record every extension we can open.  Many of the extensions that we support are "discovered" during the launch at various libraries installed and plug-ins, we wonder what they take over.  For example of formats supported by QuickTime may change with different QuickTime components install you, and the formats supported by AudioToolbox can change with versions of Mac OS X.

The extensions that we even do not match in the dialog below.

That being said, we can by adding *.m4a to our default plist.

  • Problems when opening a photo directly with lightroom (excluding a file with the "Open with" option)

    Hi, when I installed everything first to lightroom, I open images directly into a folder with a right click on the image and choose 'Open with' option. Lightroom is a program offered in the list. After update of lightroom, the program is no longer in the list. I could manually choose the path and the exe file, but it still doesn't work.

    I found somewhere on the internet a solution where we had to change some paths in the registry for lightroom and delete the other values. He worked thereafter (apparently, the values in the registry is not updated during the update of the programme). When I switched to lightroom 6 is the same thing (can't directly open images more). Unfortunately, I didn't copy the page with the solution and I can't find any more. Anyone know how to fix this?

    OK, I found the solution: How do I put Lightroom.4.2 in 'Open with'?

For more information about how to back up and restore the registry, click the following windows Help article.

    Back up the registry

    Follow these steps and check if it helps to fix the problem:
     
    a. open the Registry Editor (start > run > regedit) and navigate to:
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\Explorer
    (b) in the right side of the screen double click on "NoFileAssociate".
    c. change the value of "NoFileAssociate" from 1 to 0.
    d. now go to:
    HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\Explorer
    e. Repeat steps 2 and 3.
    f. close "regedit" and restart your machine.
     
    If the procedure above does not work for you (or if you already have "NoFileAssociate" of values such as 0), restart in safe mode and change a file type to open it with a program by default (or right-click and select 'Open with' for this type of file and check whether or not the box is still greyed out) and click OK. The next reboot to fix the problem.

  • Icon of Page Options missing for the user dashboard


    Hello

    Does anyone know why a user would have the Page Options icon (where they can export, print, save customization, etc.) missing from a dashboard?

    It certainly has nothing to do with the browser - behaves the same on different browsers. Here are some details:

    1. the 11.1.1.7.140527 OBIEE

    2. use IE9, Chrome, FireFox, nothing works

    3. This is why I know that's not browser related. I logged in OBIEE on their computer, and the icon is not absent, when they connect, it is absent. On my computer, I don't have the issue of a missing icon, but when they were connecting through my computer, the icon was missing.

    4. This leads me to believe that this has to do with safety, however...

    To mimic the safety of the user, I have myself removed from all security roles had I and replace them with the same PRECISE roles as long as the user has the question (cloned the user roles) and did not have a problem with the missing icon. In addition, there are about 100 users with the same security as the user experiencing the problem, no one else has this problem.

    Any ideas?

    Thanks to all that gave helpful suggestions...

    It was from that user could, under my accounts tab preference, the Mode of accessibility in position 'On '. In 'Off' position, he solved the problem. At some point, they must have, page login, select the Accessibility Mode option, which changed their preference. Even if subsequent connections lacked the selected box, preference has been set yet. Either they went straight to the preference tab and made the change it.

    If the problem persists, you can try uninstalling and reinstalling adobe.

    You can try to uninstall all older versions, Adobe Acrobat , and see if the problem is resolved. Uninstall earlier versions of the application and then install the version you want. If multiple versions of Adobe Reader are installed on the system, remove all versions and install only one version.
    To do this, follow these steps:
    1. click on Start, type Appwiz.cpl in the Start Search box, and then click Appwiz.cpl in the list of found files.
    2. double-click on the version of Acrobat or reader you want to uninstall.
    3. click on Yes if you are prompted to confirm that you want to uninstall the program.
    Note If you are prompted to confirm that you want to run the program, click on allow.
    4. click Yes to restart the computer.
