macOS 14 Sonoma save file dialog not showing

lsbts1291

With the latest update of macOS 14 Sonoma the file save dialog or the file open dialog are no longer showed. In the console log the following error appear:

[OpenSavePanels] Unable to display save panel (unrecognized error: Error Domain=NSCocoaErrorDomain Code=4099 "The connection to service created from an endpoint was invalidated from this process." UserInfo={NSDebugDescription=The connection to service created from an endpoint was invalidated from this process.})

I build and run the qt example Text edit, and there it is working correctly.

Someone can give some explanations?

We found the problem.

In our info.plist file there was a wrong entry, it is since 8 years like that, but curiously only starting with macOS 14 Sonoma this was giving problems.

Wrong:

<key>CFBundleDevelopmentRegion</key>
        <string>Switzerland (italian)</string>

Right:

<key>CFBundleDevelopmentRegion</key>
         <string>it-CH</string>

@lsbts1291 What Qt version do you use?

Hi,

In addition to what @jsulm requested, since the Qt example is working fine, did you try to compare what you do differently in your application ?

I'm using Qt 6.5.2. I compared the code, and there are no differences in the way we call QFileDialog, may be the problem is the cmake or plist files.

I have this same problem and open/save dialogs don't work at all, and there's nothing wrong with my Info.plist file. I downloaded and installed from the online installer today (I was using 6.5.0, now 6.5.3). I tried to build the examples and open/save dialogs don't work, even in Qt Creator!
