Hi altestudio,
I have already answered you here:

Anyway, about OCIO/ACES support, it is not available for Metal Intel/AMD.
OctaneX PR versions are still based on 2020.1.5 SDK, with some addictions, while OCIO/ACES support has been added in 2020.2 SDK, in the CUDA version.
OCIO/ACES support for Metal is available only in the first alpha version for OctaneX Standalone based on 2022.1-XB1 SDK:

This is the first OctaneX version in pair with Octane CUDA SDK, but it works only with Apple Silicon M1.
We are expecting to have the first c4doctaneX 2022.1-XB2 M1 plugin in the coming weeks, also compatible with R26.
ciao,
Beppe
