64-bit Pd works fine on macOS 11 (Big Sur). As far as I recall, all of the external builds from Pd-extended were compiled as "fat libs" with ppc, 32, & 64 bit intel.

On a related note:

The bigger move is to support Apple's new arm64 architecture (currently the M1 cpu). I have a new MBP with an M1 and Pd builds fine. The current issue is that building the custom Tcl/Tk we need for macOS has issues and we are waiting for them to be fixed upstream by the Tk devs. Externals will need to be recompiled to support the new arm64 architecture and this can also be done with "fat libs" that can support both x86_64 (Intel) and arm64. For now, running the Pd 64-bit Intel build works fine, more or less seamlessly via Rosetta 2.

What about big sur ?

I installed it just to test, I don't really use it, but I could install Pd and also get an old library like "unauthorized" from deken and it worked. I tested the "grid" GUI external and it was fine. So I guess it all should just work as well.
