Can you test the latest HEAD please? Either 6753750bf2487b029947f3d61a5c51a640210d7b or 99e32964237b4c559f83f4e34f3d9025647cf473 should address this, it is now able to find my installed library on a native M1 mac.

Hrm. The second exception is my mistake - that means it can't find any Homebrew installation on your system.

What is the path to libhidapi.dylib on your system, and how did you install it?

via brew, brew install hidapi

/opt/homebrew/lib/libhidapi.dylib /opt/homebrew/Cellar/hidapi/0.12.0/lib/libhidapi.dylib

I tried to hardcode homebrew_prefix = "/opt/homebrew/" and it worked, thanks for your help.

Found 1 Stream Deck(s).

Deck 0 - Stream Deck Original.
