      I have an application developed with Qt 5.5.1 on a system running OS X 10.10.5. The application will not open for a user attempting to use it on OS X 10.6.8. The problem report states that "App cannot be opened because of a problem." I have deployed the application bundle on my system where it works fine. Are there issues with deploying to 10.6.8 (Snow Leopard)?

        Usually on that "there is a problem" screen on osx, you can get more information. Which is basically like a crash log. Can you post that info here?

        Or barring that can you open the application in a debugger and show us the info from that?

        And final question, did you limit your target osx platform when you built? Something like:

        QMAKE_CFLAGS += -mmacosx-version-min=10.6
        QMAKE_CXXFLAGS += -mmacosx-version-min=10.6
        

        Or did you use something like:

        macx:QMAKE_MACOSX_DEPLOYMENT_TARGET = 10.6
        

        in your project file? ^ had to look that one up, I use cmake these days and couldn't remember the syntax.

          10.6 support was drop, I think Qt 5.3.2 is the last version to support it.

            10.6 was dropped as a build platform however applications should be able to run on it (provided that no API from newer version of OS X are used)

              @SGaist said:

              ...(provided that no API from newer version of OS X are used)

              That's exactly what happen, newer API are now used unconditionally and 10.6 fallback has been removed.

              see:

              etc

              That was for Qt5.4, so like I said, stick with Qt5.3.2 for 10.6 support.

                Fair enough, then the documentation is not reflecting that move.

                  I went back to version Qt5.3.2 and now the app developed with it on a recent OS X runs on OS X 10.6.8. Thanks for the advice.
