Need I set the nativeRebuilder to 'legacy'?

This doesn't look related to the native rebuilder as it looks like this is an error at runtime. Is that correct? It also looks like a dependency on your system is not installed

But how do we package local dependencies into the application? We shouldn’t assume that the user has this dependency locally, right?

Hi, i got this issue as well, when first time running it. How do I resolve it?

Yes, I resolved this issue.
First, you need to create an afterPack.js script to fix the path. The problem arises because the serialport library depends on a dynamic library from the local LLVM.
You need to locate the libunwind.1.dylib file in your local LLVM and place it in your project. Its path is: /opt/homebrew/opt/llvm/lib/libunwind.1.dylib.
It is worth noting that on macOS, we typically use Homebrew for installations. Homebrew creates symlinks for dynamic libraries, which are pointers to the actual files. If you find that your local libunwind.1.dylib file is only a few bytes in size, it is likely a symlink. Run ls -l /opt/homebrew/opt/llvm/lib/libunwind.1.dylib to locate the actual file. Copy this file into your repository; I placed it in the resources directory.
Next, here’s the key step: execute the necessary commands in the afterPack.js script.

install_name_tool -change \
/opt/homebrew/opt/llvm/lib/libunwind.1.dylib \
@executable_path/../resources/lib/libunwind.1.dylib \
"./dist/mac-arm64/test.app/Contents/Resources/app.asar.unpacked/node_modules/@serialport/bindings-cpp/build/Release/bindings.node"

This command will redirect the dependency path in bindings.node from local to your project.
