I get the same error on an Intel Mac with macOS 12.0.1.

[LouisBrunner]

M1 (and Big Sur and later) is unsupported at the moment LouisBrunner/valgrind-macos#19

[8-bit-owl]

Apparently, valgrind doesn't work with M1/M2 Macs coz they are ARM based. This --HEAD of this tool only supports intel based Macs.
