Heatmap not working on macOS (OpenGL 4.3 required, macOS only supports 4.1) – 2D fallback needed

Hello ATAS Team,

I’m running ATAS X (Beta) on a 2019 MacBook Pro (Intel i9, AMD Radeon Pro 5500M, 16 GB RAM, macOS 15.x) and the Heatmap does not work at all. After extensive troubleshooting I believe I’ve found the cause and would like to request a specific fix.

Root cause:
The Heatmap (and possibly only its 3D rendering mode) requires OpenGL 4.3. Apple deprecated OpenGL years ago and locked macOS support at OpenGL 4.1. This means the Heatmap cannot initialise on any Mac, regardless of hardware, because the system simply doesn’t offer the required OpenGL version.

What I’ve tried:

• Forcing the dedicated AMD GPU (via gSwitch and editing Info.plist with NSSupportsAutomaticGraphicsSwitching = false)

• Checking for hidden config files inside the app bundle (none found)

• Looking for a “Metal” API switch in settings (not present)
  None of these workarounds help because the 4.1 → 4.3 gap is a hard macOS limitation.

My theory / request:
It’s likely the 3D Heatmap is the part that demands OpenGL 4.3. I (and many traders) only need the 2D Heatmap – the 3D mode is a nice addition, but not essential. The problem is that the 3D requirement seems to disable the entire Heatmap feature, even in 2D view.

What I’m asking for:

1. A 2D-only fallback mode for the Heatmap that uses a lower OpenGL version (4.1 or below) or software rendering. If the 3D renderer fails to start, the app should gracefully fall back to a 2D view instead of breaking completely.

2. Long-term: Metal support for the macOS version. Apple’s Metal API is the future on Mac and would completely solve this and any future graphics compatibility issues.

This issue affects every Intel Mac user (and possibly Apple Silicon Macs too, if OpenGL translation layers also cap at 4.1). I’d be happy to provide logs, system details, or test any beta builds if you decide to implement a 2D fallback.

Thank you for your time and for an otherwise excellent platform.
