Never mind! The program starts after about 1 minute 30 seconds, I just have to wait without pressing the emulated screen/phone

Hi and welcome to devnet, Try something like: QUrl url("file:///Users/your_user/your_file.extension"); NSURL *nsUrl = url.toNSURL(); NSError *error = nil; NSData *bookmark = [nsUrl bookmarkDataWithOptions:NSURLBookmarkCreationWithSecurityScope includingResourceValuesForKeys:nil relativeToURL:nil error:&error]; qDebug() << "Error" << error; qDebug() << QByteArray::fromNSData(bookmark); Hope it helps

Thank you both very much for your help. I had a suspect that the problem was related to power saving because when on AC the problem was still present but intervals with no communication were shorter. Unfortunately I won't be able to test the solution in the linked page before a week or so. I will read something about App Nap in the meanwhile, now that I know what to look for :-)

Hi everyone! I've solved this problem. In my case the problem was in asynchronous load images into another thread. When I changed asynchronous method to the synchronous all work fine.

@VRonin thanks! i saw that in my searching, but at first thought it was a Qt issue, not a generic app issue. looking closer at that link, I got it fixed. Thanks!

Thanks for sharing your findings !

@patrik08 : I am trying to mix normal QT application with Swift code in order to load the receipt of purchasing an app from app store as requested in this, since you have good experience with Swift and QT C++ code, i would appreciate if you provide an example for this case to the tracker. Thanks alot https://bugreports.qt.io/browse/QTBUG-76665

@SGaist said in Mac OSX Read all file not defined... Is this a bug? in qt5.9: Q_WS_MAC Ok... tanks.... so many different variable in the last 10 years... uauu... other DEV-T to all QT oldtimer guy... I set now new my pro file... DEFINES += DEF-T message( "DEV-T - Developed Unnecessary Traffic you find all new inside QT5" )

While I'm still not successful to expand $${LITERAL_DOLLAR}0 to the command line at compile, I did resolve the generated compile error by changing from awk to sed. [Work around] Change... myrcupdate.commands = awk \'NR==2 {$${LITERAL_DOLLAR}0=\"$${MY_DIR}\"} 1\' myrc.sample > .myrc to... myrcupdate.commands = sed -i \'\' \'2s%.*%$${MY_DIR}%\' .myrc

when MACOSX10.13 was coming, the only way to fix is creating symbolic MacOSX10.13.sdk to MacOSX.sdk which is able to fix problem.

Great! Thanks for sharing your solution!

@VRonin Thank you for the suggestion. The Windows 10 behavior (meaning display issues) it's the same on MacOSX. On Windows 10 I'm building with MSVC2015_64bit. On MacOSX with clang 64 bit. However, the sound playback issues in iOS devices are far more annoying for me at this point.

@Wieland said: I'm pretty sure there is no ootb solution to do that. Why do you want to render the background when it's not possible? Maybe we can find another solution. This is because I have a real-time video streaming and the frames are rendering in main QQuickWindow context. I think otherwise I need to create another opengl context and run rendering in it. Or maybe there is some way to use the same QQuickWindow context to do that?

When are you setting that attribute ?

I saw that this bug has been reported.

@sneubert Well, that's what I did not want to hear at all :) , but thanks anyway.

@Almer_Cz said: ...and also create .pro and let qmake to generate XCode project, but this will produce a lot of Mambo Jambo around and won't be handy when something changes. So your looking for a way to create and maintain the Mambo Jambo manually and this will somehow be more handy ?

I'd generate the Xcode project from a .pro file, that way you have everything setup for you

Hi and welcome to devnet, Are you experiencing the same with Qt 5.5 ?

Compiled and rebuilt with Qt5.5.0 (beta). Unfortunately, the problem persists.

Hi SGaist, Thanks for the tip. I made a comment on the linked bug. Hopefully, that helps someone!
