I have successfully created a signed macOS pkg installer file for DreamLisp binary. It includes the dlisp binary and DreamLisp.framework files. It installs the binary to /usr/local/bin and the framework to /usr/local/Frameworks folder. The pkg file is 411 KB. It is signed and notorized using my Apple Developer certificate.

The installer is available from GitHub, DreamLisp-v1.2.pkg.

After installation run dlisp in the Terminal for the DreamLisp REPL.

NB: The binary is from a release build on my Intel mac. It won't work on Apple Silicon.
