What the developer wrote
Authored by Peter D. Gray
updates for Tahoe
What changed, and why it matters
This commit only updates build instructions and a Makefile for compiling the COLDCARD simulator on macOS. It removes a hardcoded PKG_CONFIG_PATH workaround and updates the README to tell users to install pkgconf and libffi themselves. There is no change to firmware code, wallet logic, cryptography, or anything that handles secrets or transactions.
No security action required. Treat as routine build documentation/maintenance.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The diff removes an exported PKG_CONFIG_PATH override from unix/Makefile and revises unix/README.md macOS build guidance. It is a build-system/documentation hygiene change for the Unix simulator port. No source files affecting runtime behavior, secure boot, key handling, or communication protocols are modified.
