1. I had problem on intel mac when installed qt6.2 (qt5.15 was already 
installed) , but make clean and removing .qmake_stash and .qcmake_xx 
files manually from cbindings directory helped me a lot. So maybe you 
should remove such files and then start qmake-6 again (for arm).

2.On newer macs Library/Frameworks is not in path by default, I've found 
that symlinking Qt5Pas to Library/Frameworks and 
/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks 
fixed problem for make bigide.

3.You should add "-k -F/Library/Frameworks" to the configure "Build 
Lazarus" dialog if you want to rebuild lazarus for Qt5, or for your 
projects in Project Options check "Pass options with linker with "k" 
...." -F/Library/Frameworks and then it should work
