OpenRAR for Mac 1.0 — source code of the LGPL components it ships (GNU LGPL 2.1, section 6).

7z2605-src.tar.xz                7-Zip 26.05 by Igor Pavlov, unmodified. OpenRAR ships its console "7zz", built from
                                 this source by build-engines.sh (universal arm64 + x86_64, macOS 14).
XADMaster-1.10.8.tar.gz          XADMaster 1.10.8 (MacPaw), shipped as the programs "unar" and "lsar".
universal-detector-1.1.tar.gz    UniversalDetector 1.1 (MacPaw), linked into unar and lsar.
xadmaster-password-stdin.sh      OpenRAR's only changes to XADMaster: "-p -" reads the password from standard
                                 input; libc++ instead of libstdc++ at link time.
build-engines.sh                 How OpenRAR builds every engine from these exact archives (SHA-256 pinned).

These programs run as separate executables inside OpenRAR.app/Contents/MacOS; you may replace them with your own
builds. Questions: support@openrar.app — Yando Pte. Ltd., 68 Circular Road, #02-01, Singapore 049422.
