Yeah, totally agree, Apple just doesn’t seem to care. Absurd! Fingers crossed OTOY pushes a fix soon.

Hey David, when you say “the same procedure every year”, what do you mean exactly? Just waiting for OTOY to catch up after the macOS release, or do you usually follow some specific workaround in the meantime?

I’ve also tried running Octane X (integrated in Cinema 4D, version 2025.3) on macOS 26 with an M3 Max, and I can confirm the same issue: Octane doesn’t recognize any GPU at all. Everything was working fine before the OS update, so this looks like a compatibility problem with the new macOS drivers ...
