        @Justinxiang You could try to build Qt by yourself which is not an easy task

              Is there a solution for this issue. I have Qt6, but the issue persists.

                This is the code in .pro. I used homebrew to install opencv4.

                QT += core gui

                greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

                CONFIG += c++11
                CONFIG += arm64

                SOURCES +=
                main.cpp
                opencvmain.cpp

                HEADERS +=
                opencvmain.h

                FORMS +=
                opencvmain.ui

                INCLUDEPATH += -I/opt/homebrew/Cellar/opencv/4.5.2_4/include/opencv4
                INCLUDEPATH += -I/opt/homebrew/Cellar/opencv/4.5.2_4/lib
                INCLUDEPATH += -I/opt/homebrew/Cellar/opencv/4.5.2_4/bin
                LIBS += pkg-config --cflags --libs opencv4

                LIBS += -framework CoreFoundation
                LIBS += -framework IOKit

                LIBS += -L/opt/homebrew/Cellar/opencv/4.5.2_4/lib
                -lopencv_core
                -lopencv_highgui
                -lopencv_imgproc
                -lopencv_core

                QT_CONFIG -= no-pkg-config
                CONFIG += link_pkgconfig
                PKGCONFIG += opencv4

                  What issue do you mean? Qt built for x86_64?
                  There is no official M1 ARM builds of Qt yet.
                  You can either build Qt by yourself or use OpenCV x86_64 build.

                    Thanks for the replay. I have a Mac M1 and I cannot build. I get the following error.

                    ld: warning: ignoring file /opt/homebrew/Cellar/opencv/4.5.2_4/lib/libopencv_alphamat.dylib, building for macOS-x86_64 but attempting to link with file built for macOS-arm64

                    Error while building/deploying pro
                    If Qt does not support M1 could you please recommend a resource that I can follow to build and run opencv.
