I want to know how to install protoBuf in MacBook Pro in Apple M1 chip. Anyone known the solution?
It appears that protocol buffers are still migrating to M1 support. Until then, you can presumably run them with Rosetta2's x86 emulation. They'll show up in the releases page.
Edit: As of version 21 (May, 2022), there is a "Universal build" (see the releases page).
