QtCreator fails on MacOS SDK 12.3

[Dannylove1026]

My QT version is 5.12.12

I have MacOS Monterey 12.6

When I create a new standard project in QtCreator I get the following error and the mainwindow didn't came out:

:-1: warning: Project WARNING: Qt has only been tested with version 11.0 of the platform SDK, you're using 12.3.
:-1: warning: Project WARNING: This is an unsupported configuration. You may experience build issues, and by using
:-1: warning: Project WARNING: the 12.3 SDK you are opting in to new features that Qt has not been prepared for.
:-1: warning: Project WARNING: Please downgrade the SDK you use to build your app to version 11.0, or configure
:-1: warning: Project WARNING: with CONFIG+=sdk_no_version_check when running qmake to silence this warning.

Below is the screenshot for the error

I've try several methods, including add those commands in the .pro file:

QMAKE_MACOSX_DEPLOYMENT_TARGET = 10.15
CONFIG += sdk_no_version_check

It still didn't work out.

When I type xcodebuild -showsdks, I get:

Do you know how to solve this problem? I've been working on it for days, I'm really appreciate anyone for solving this.

Hi and welcome to devnet,

The real solution would be to build Qt with that SDK however it is mainly a warning so unless your application crashes, you can develop it further.

That said, after you added the CONFIG variable, did you re-run qmake before building ?

@SGaist Hello SGaist, I restart the QT and then rebuild and run qmake for the project, the result was still the same

[SGaist]

And beside these warnings, do you have issues with your application ?

@SGaist Hi SGaist, sorry for the late reply, the only question is the mainwindow didn't show even in the simplest default project

@SGaist Hi SGaist, the warning disappear after I downgraded my Xcode, however, a worse problem has emerged, can you help me with this? on my latest post.
