 ```sh
-lipo -create -output target/release/libmy_lib.macos.dylib target/aarch64-apple-darwin/release/libmy_lib.dylib target/x86_64-apple-darwin/release/libmy_lib.dylib

+    target/aarch64-apple-darwin/release/lib{YourCrate}.dylib \
+    target/x86_64-apple-darwin/release/lib{YourCrate}.dylib
 ```
