Got a macOS build of HiFi Streamer Pro up!

Our test system is a Mac Mini M1, so that is essentially the minimum system requirements, any Mac with Apple Silicon will run HiFi Streamer Pro fine!

For WASAPI exclusive mode, it doesn't exist in the MacOS world, the 'W' in WASAPI is "Windows". so in here we have substituted "Core Audio AudioQueue exclusive mode", which should play at the sample rate bypassing the mixer.

"Audio Queue Services is a high-level, C-based programming interface within Apple's Core Audio[developer.apple.com] framework (specifically inside [c]AudioToolbox.framework[/c]). It acts as a bridge between low-level hardware abstractions (like Audio Units) and your application, making it the go-to choice for recording, playing back, pausing, looping, and synchronizing audio without dealing directly with raw hardware abstractions."

So that is how it will work on HiFi Streamer Pro in macOS. I have limited external hardware to test with so post in the discussions if you encounter any issues. This will be continually be maintained so there will be many possible adjustments coming or oversights to fix, but in the current state it appears to work great, even Lumen visualizer DLC works perfect.
