On macOS, Houdini uses the system’s Python.framework and only displays errors at its Alert level (LOG_ALERT recorded on /var/log/system.log). AFAIK there isn't a default daemon that's logging debug or exception errors at the system level that would appear in the Console.app. Looks like macOS does a hand off to what ever app is using its Python for that, so my guess is you can use HOM to store and retrieve arbitrary data on individual nodes [www.sidefx.com] to print to Houdini's Python console.

Hopefully, a Houdini Python expert will fill us in on these missing pieces of the error logging puzzle.

“Metal for Mac works almost identically to its iOS counterpart, as developers can stack on apps on core animation and core graphics, as well as built-in OpenGL and OpenCL API support. While the most obvious use of Metal is for games, Adobe found huge improvements by stacking After Effects and Illustrator on Metal.”

So now that Metal is gaining momentum with Apple developers, and OGL will not be upgraded for future macOS's as a result of Metal's growing popularity; it appears that SideFX/Houdini will need to decide their future direction for the Mac platform very soon.

I find it very intense and stressful for SideFX to struggle with the fading OGL support on macOS but feel very optimistic regarding Houdini's future support of Metal because of all of its benefits that Houdini can now take advantage of. Its exciting to hear about other game developers, 3D & 2D software developers discovering greater performance when transitioning their software to Apple Metal.
