Will the next macOS release be a Universal binary so it runs natively on the new M1 Macs?
For now, Qt does not appear to support the ARM architecture for macOS (only for iOS) and it will also need to support the building of universal binaries, for which they have issue https://bugreports.qt.io/browse/QTBUG-85447 open. As soon as Qt supports this I can look into building universal binaries of Tiled.
