Has this feature been discussed and generally agreed?

Apple M1 is currently supported via Rosetta 2. There is demand for native builds. This issue tracks the required work.

Describe the solution you'd like

• Code: Add Qt6 compatibility #2299
• Switch to create-dmg #2207
• Autobuild: Mac: Build with Qt 6.3.1 #2672
• Autobuild: Add macOS M1 (arm64) build target #2682
• Mac: Sign non-release builds with self-signed key #2791
• Mac: Provide universal binaries for x86_64 & arm64e #2790

Describe alternatives that have been considered

There've been no reports about problems with running the x86_64 builds via Rosetta 2 on M1. Still, running something latency-critical as Jamulus via potentially avoidable translation layers sounds non-optimal.
