    A heads up to save someone some hours figuring out what this is:
    The mac store now rejects even (empty) unity 4.3.1 projects with the following reason:


    I submitted an bug report to Unity and have appealed the rejection at apple. I hope of of the two parties comes with a solution.

    So, here's what I found out on this so far:

    Our web cam code uses the QTKit framework, which is deprecated in 10.9, which is why Apple is not accepting submissions for the app store. The solution to this is to rewrite the web cam code to use the newer AVFoundation framework instead. Luckily, that is not too hard, as we already use that code on iOS.

    It is somewhat annoying, however, as we already rewrote that code just a few months ago to use QTKit (up from the even older Sequence Grabber API), because QTKit was not yet deprecated at that point, and, unlike AVFoundation also supports 10.6 (which is still our current minimum spec for OS X). This also means that we will lose web cam support on OS X 10.6, but I think if the choice is between keeping web cam support on 10.6, and Mac App Store publishing support, the solution is obviously to keep MAS support.

    So, I will fix this code to use the non-deprecated AVFoundation framework for 4.5. The question for us to find out, is if this fix will go back to 4.3.2 (as it is not a trivial change), or if we'd rather chose a faster fix by temporarily disabling webcam support in OS X standalones to fix this. Does anyone critically need web cam support in OS X standalone?

    Thanks for the reply Jonas.
    I don't know any devs who need webcam support in OS X standalone. Disabling webcam support for now sounds like a better option then not having any working mac store apps at all. All webcam enabled apps cannot be submitted either. Those who use webcam and do not use the store can always use 4.3 or the current 4.3.1.
    Our Mac store launch is eagerly waiting for a fix since Apple even denied a complaint ticket and keeps to their new policy.

    I'd have to also agree with temporarily disabling webcam support; the company I work for has me under the gun to submit an OSX build to Apple before Apple's winter/Christmas deadline (for a cross-platform launch). Our app doesn't use the webcam in osx either. Thanks for the reply Jonas, please post in this thread if a hotfix/patch release is pushed out!

    Another vote for temporary solutions while some well-tested code is underway. Web cam code may be rarely used, but I have pondered it for a prototype (gaming tools). Maybe at the same time check that third-party components like FMOD aren't also using anything likely to be deprecated soon!

    i vote too for disabling the webcam, having unity not able to publish to the mac store until a new major release is not a good idea, quick temporary fix please

    I don't want to hound someone, but can anybody tell me when the webcam support will be re-enabled (with the new AVFoundation Webcam)

    Nobody can tell you that. Maybe the next version if it's not a big project, otherwise a later version.

    That's not going to help if it's blocking MAS approval.

    Yes I know.
    It was only a question. I haven't a MAS account but I am a Mac user and now I make some experiments with the webcam and the microphone functions. But I don't like it to use old versions for a long time. I hope the AVFoundation don't make any problems ;)

    Hi! I'm using Unity3D 4.3.1f1 and also got the same message when trying to submit to the Mac App Store:

    What should I do as I need to submit this app ASAP for a client? Should I downgrade to some other version of Unity? Please help!

    Note: My app does NOT use any webcam or quicktime functionality, is it possible to disable that somehow?

    Just like to add my voice.... Currently working on an application that depends on crowd participation. I had hoped that Mac WebCam support would have made it into Version 5. (I'm assuming it hasn't as crashes on myWebCamTexture.Play(), whilst fine on PC version). The event is in November so a bit of time, but....

    WebCam support for OS X has been back for quiet a while now. If it crashes, submit a bug report.

    How are people processing video to get around the rejection of QKit?
