Nik 4 and Mac Silicon

I just traded in my old MacBook Pro for a new (and very fast) Mac Silicon machine. Processing with PhotoLab 5 (I have not upgraded to 6 yet) is very fast but I downloaded and installed my Nik 4 collection. Unfortunately some of the modules do not work properly on the M2 chip and I was wondering if the Nik 4 stuff was supposed to be supported under Mac Silicon. Does anyone know? Is Nik 5 supported under Silicon?

nik 5 is supported for m2 chips, not any earlier version.

Thank you.

I assumed that might be the issue when the Nik 4 stuff either would not load or acted very strangely, and now I know.
