I did some new tests, and I confirm that on a macOS 11.6 running on a MacMini 2020 M1 it throws the exception, as shown before, when testing a build performed on a macOS 11.6.

However, on an Intel macOS 11.6, a QEMU 6.2 built --with-sdl on an old macOS 10.13, managed to start, and I got a graphical window, which was a bit surprising:

However, the console displayed the following:

In other words: "WARNING: NSWindow drag regions should only be invalidated on the Main Thread! This will throw an exception in the future.", which is exactly what happened on builds performed on more recent macOS.

I will try to rebuild using --with-cocoa on newer systems, to validate the rest of the build.
