For example,
$ CGO_ENABLED=0 GOOS=darwin GOARCH=amd64 go build -o amd64 example/main.go
$ CGO_ENABLED=0 GOOS=darwin GOARCH=arm64 go build -o arm64 example/main.go
$ lipo -output hello-world -create arm64 amd64
$ ./hello-world
Hello World
$ file hello-world
hello-world: Mach-O universal binary with 2 architectures: [x86_64:Mach-O 64-bit executable x86_64] [arm64]
hello-world (for architecture x86_64): Mach-O 64-bit executable x86_64
hello-world (for architecture arm64): Mach-O 64-bit executable arm64
